Illinois, Yeah, Reno, Veno, Highspeed and Vegas). By changingthe link characteristics at the client side, the overall efficiency ofthe connection can be improved. In our paper we have examinedthe working of these algorithms over a file transfer from a server.To improve the link performance we have changed receiverbuffer size, sender buffer size and different link parameters onLinux and analyzed the results on Wireshark. We have comparedthe results of all these algorithms in terms of Round Trip Time(RTT), Bandwidth efficiency, Packet loss and Download time tofind the best working algorithm.Index Terms: High speed Transport Protocol, TCP tuning inLINUX, HTCP, TCP congestion avoidanceReferences: 1.

Group name: R03 MAKTThe Paper Title: Performance Analysis of aSynchronized Variable Data Rate OFDM System.Authors manes: Matiullah Khan, Muhammad MustafaTahseen, Ariful Islam.Abstract: One of the most important tasks in OFDMsystem is to achieve perfect synchronization betweensub-carriers. Performance of OFDM system is adverselyaffected by synchronization errors and with occurrence ofvery high peak values in data signals. An efficient OFDMsystem will be that one, in which receiver is expected tocompute the spectral values at those points correspondingto the maxima of individual sub-carriers. We propose tomaintain synchronization in OFDM system that can bedone by finding the maxima of sub-carriers by using thepre-defined threshold detection value technique.Implementation of this technique in MATLAB givescomparatively high performance than the

non-synchronized OFDM techniques.Index Terms: OFDM, ISI, ICI, BERReferences:[1] M. Mourad, H. Salem, B.

Group name: R06_ PionjrerTitle: Performance of Multicarrier Code Division MultipleAccess over Rayleigh Fading ChannelAuthors: G.A.Jafri, M.Faisal & S.E.YilmazerAbstract: Multi-Carrier Code Division Multiple AccessSchemes (MC-CDMA) are recently introduced in existingCDMA based systems to improve security, data transmissionrate and to minimize Inter Symbol Interference (ISI). CDMAexperience severe multipath fading which badly affects its

performance. By transmitting identical narrowbandDirect-Sequence (DS) waveforms using frequency diversity, inparallel with number of sub channels, multipath fading could beminimized. Implementation of this multi-carrier modulationtechnique in CDMA system is known as multi-carrier CDMA.In Rayleigh fading channel, due to multi-carrier modulation,when one subcarrier goes deep fade another subcarrier remainssafe. Therefore MC-CDMA can combats multi-path fadingbetter than CDMA and signal can be received in low bit errorrate.Index Terms: MC-CDMA, Rayleigh Channels, IntersymbolinterferenceReferences:[1] R.

Studies by FCC (Federal CommunicationsCommission) shows that lot of fixed assigned spectrum are notused efficiently. Such kind of spectrum scarcity can beovercome by the use of cognitive radios. Cognitive radio hasthe capability to allow the secondary users (SUs) to use thewireless licensed spectrum when it is not used by the primaryusers (PUs).

Group Name: - S01 GladaPaper title: - MODIFIED LMS BASED ALGORITHM forNOISE CANCELLATION in SPEECH ENHANCEMENTAuthors Names:-Abel G. Mangam, AbhiramChintakuntla, Mamun AhmedAbstract: Speech enhancement is involved with theprocessing of the speech signal corrupted by noise in orderto improve the quality. In many noise cancellation

techniques, the change of the signal characteristics could befast which requires the use of adaptive algorithms thatconverges rapidly. The conventional Least Mean Square(LMS) algorithm has some drawbacks like lowconvergence speed and the higher computational complexityin real time speech enhancement. To overcome this, a newmodified LMS based algorithm with momentum isintroduced for a better convergence. The modified algorithmalso has a low computational complexity as it uses the blockbased approach.Index terms: - Adaptive Noise Cancellation, Convergence,LMS Algorithm, Speech Enhancement.References:-[1]B.Farhang-Boroujeny, Analysis of the frequency

Group name: S02 skaThe Paper Title: Finding the Epipoles of a Sequence ofImages for the Pure Forward Translation of the Camera.Authors' names: Ravitej reddy Gopavaram, HamidurRahman, Sarath Chandra UppalapatiAbstract- This paper deals with the computation of epipoles ofa sequence of images for the forward movement of the camera.If the images are taken from a moving camera, the pixel values

of each image changes and finding epipoles becomes verydifficult in that case. A better performance can be achieved bycapturing a sequence of images for a small translation of thecamera and then finding epipoles of each image. However,epipoles can be computed for any directional movement of thecamera. The problem is investigated with emphasis on itsapplication to autonomous robots and land vehicles.Index Terms: Camera Motion, Epipolar Line, Epipole,Fundamental Matrix.References:[1] F.

Husain, Deepak K.EethakotiAbstract : Depth estimation using a single monocular image hasbeen a subject of significant research recently. Most of the focusis on using probabilistic methods applied on raw data, whichyields poor results. However, the performance can be improved,if visual cues like contour length that have a correlation withdepth are extracted first. In this paper we present a new methodfor depth estimation of objects present inside a single monocularimage. SURF descriptors are used to identify objects in an imageand phase congruency based edge detection is used to calculatetheir contour length. The contour length when compared to thepredetermined contour length of the same object yields depthinformation.Index Terms : Edge detection, Phase congruency, SURFdescriptors, Template matching .References :

To do socooperative communication uses two types of diversitytechniques called Decode and Forward (DF) and Amplifyand Forward (AF) diversity techniques. In order for the DFdiversity technique to be efficient different errorcompensation mechanisms are being used.In this paper repetition code, Reed-Solomon code and lowdensity parity check code, which are error compensationmechanisms, that are used to reduce the bit error rate (BER)in DF diversity technique will be compared.

In this paper, we tried toovercome this problem by applying Vector Quantization (VQ) toblock wise PCA. In this approach, instead of applying PCA to thewhole data, the data is divided into set of blocks and then PCA isapplied to each block which results in more efficiency and highcompression rate with low information loss.Index Terms: Image compression, PCA, Vector Quantization.References:[1] R.

Sabil Sajjad, Bulli Koteswararao.Kommineni and Gannamaneni Geetha Chowdary.Abstract: Vehicle detection plays an important role in trafficcontrol and management. In this paper we have performedvehicle detection based on image processing. For the vehicledetection only the boundary edges are needed. Conventional

CANNY edge detection has some inadequacies as it detectsonly the boundary edges of the vehicle. In order to achieve abetter detection of the boundaries of the vehicles, we usedimproved CANNY edge detection algorithm along with asequence of morphological operations on the images taken byusing aerial cameras. To improve the performance of CANNYoperator, we used self-adaptive filter instead of Gaussian filter.Our main objective is to achieve the prominent edge detectionresults of the vehicles and count the number of vehicles.Index Terms:Adaptive filter, Canny algorithm, Morphological operation,Thresholding.References:[1] B.

In many of thebiomedical applications it is necessary to remove the

interference from ECG recordings. Several adaptive filterstructures are proposed for noise cancellation. A new, simpleand efficient LMS-based adaptive algorithm is developed foroptimal removing of interference in ECG signals is introduced.It uses a modified LMS (mLMS)algorithm to adjust filterweights according to non-stationary properties of processedsignal. The main objective of our work is to develop anadaptive algorithm to remove the contaminating signal and toobtain original ECG data. The ECG signals are simultaneouslyprocessed and analysed using the most widely used RLSalgorithm and newly developed mLMS algorithm.

So for theintelligibility we have to enhance the speech from noise

and interference. To enhance the speech and suppressthe noise, different algorithms are used. In this paper weare implementing commonly used spectral subtractionspeech enhancement algorithm, but in modulationdomain. Filter bank is heart of modulation domainwhich splits the broadband signal into several subbands. Then Instantaneous Frequency carrier estimatortechnique is used to estimate the carrier and themodulating signal of every sub band.

PHALGUNA KUMAR TALLAM, PRAPULLAKUMAR DOKKA and YOUSUF HAMEED ANSARIAbstract - The slow fading channels are of great importance incommunication systems. The study of the fading channels bringsout the noisy behaviour in the channels. In our paper we comparethe three channels AWGN, Flat fading and Frequency selective

fading in view of distorting image less by comparing the Bit errorrate(BER) and Symbol error rate(SER) of each channel withrespect to Signal to Noise ratio(SNR). We model the Flat fadingand frequency selective fading channels using Clarkes model andRayleigh distribution and then the channel estimation is done.AWGN channel distorts image less since the image is distorted byrandom noise whereas the Rayleigh fading channels are affected byrandom noise, noise due to phase distortion and dispersion.Index terms - AWGN, Bit Error Rate (BER), Channel estimation,Symbol Error Rate (SER), Signal to Noise Ratio(SNR).References:[1] Chandra A., Poram S.R., Bose C., "Performance of coherentMFSK schemes over slow flat fading channels," TENCON 2008 -2008 IEEE Region 10 Conference, vol. 3, pp.1-6, Nov. 2008.

The major problems ofImage Segmentation are random initialization andproblem with missing or hidden data. Histogram basedmodel is used to overcome the problem of randominitialization and problem with missing or hidden datacan be overcome by shaping parameter as a tool inExpectation and Maximization algorithm(EM). In thispaper, we propose an algorithm in which histogrammethod is used to find shaping parameter from DiscreteWavelet Transform (DWT) of original image. Then theEM algorithm is used to determine the final parameters.Finally segmentation of approximation coefficients isdetermined by Maximum likelihood function.

Adhikarla, Kamil Parlak, Kalyan C.Boddapati.Abstract: In this paper, we compare the performance of JointPhotographic Experts Group (JPEG) 2000 image compressionstandard with Embedded Zerotree Wavelet (EZW) coding.JPEG2000 standard uses Discrete Wavelet Transform (DWT) fortransforming the time domain image to joint time frequencydomain, which helps in providing the variable frequencyresolutions at different time instances. In JPEG2000, the DWTdecomposes the image in to its corresponding frequency sub-bands.The coefficients in each sub-band are then coded independently andtransmitted as separate bits. But this approach has a poorperformance when the transmission bandwidth is very limited. Anew encoding technique called Embedded Zerotree Wavelet(EZW) coding exploits the multi-resolution properties of wavelettransform and provides adjustable data rates for different target

MANET has different routing protocols; each hasdifferent performance in the network. This paper compares theperformance of two different MANET protocols namelyTemporally-Ordered Routing Algorithm (TORA) andOptimized Link State Routing (OLSR) by varying the PauseTime and the Network size using HTTP traffic. The analysis hadbeen done through Optimized Network Engineering Tool(OPNET) Modeler. The performance of protocols had beenanalyzed by the following metrics: Delay Time and Throughput.This paper shows that the pause time has no effect on theperformance metrics for both protocols, and it shows that OLSRhas smaller Delay Time and better Throughput than TORA.

Dynamicrouting protocols play a prominent role in enhancing theperformance of IP networks. EIGRP and IS-IS are two maininterior gateway routing protocols designed for operating incomplex network topologies. EIGRP is based on diffusingupdate algorithm (Dual) whereas IS-IS uses Dijkstraalgorithm for computing the best path through the network. .In this paper we try and compare the performance ofdistance-vector routing and link-state routing protocol.

One of the main issues inMANETs is Scalability as increase in network load makesrouting very difficult. So, it is necessary to determine theefficient routing protocol which can perform well and adaptsitself to the dynamic nature of network when network load isincreased. The purpose of this paper is to determine theefficient routing protocol by analyzing and comparing theperformance of OLSR and TORA using TCP and UDP inOPNET. Parameters like Network throughput and end-to-enddelay have been used to evaluate the performance. Evaluation

Sai Suren Kumar, MD.Ebna MasumAbstract : Using conventional filters for splitting the signal willlead to the presence of aliasing in the reconstructed signal. So,

sub banding is performed using Perfect ReconstructionQuadrature Mirror Filters (PRQMF) in order to reduce the effectof aliasing. This paper focuses on analyzing the performance oftwo-channel PRQMF and the factors that influence alias freereconstruction of signals using sub band coding. With the help ofsimulation results in MATLAB, we infer that alias freereconstruction of signal is not possible if sub bands are selectednon-uniformly.Uniform sub bands helps in maintaining thespeech quality.Index Terms: Quadrature Mirror Filter, Signal Reconstruction,Signal Synthesis.References :[1] E.

Group name: T15_DemokratiThe Paper Title: Performance comparison of AODV andDSR under TCP NEWRENO traffic.Authors names: MD Delwar Hossin, Surapaneni Ajay,Yengunola Raghavendra.Abstract: Mobile Ad hoc networks (MANET) areephemeral, self-configuring dynamic networks. TCP shows

poor performance in MANET s, because the high mobilitynature of nodes in MANET s causes the congestion in the

network. TCP NEWRENO, a flavor of TCP is a congestioncontrol algorithm and shows improved performance in

MANET s. In this paper, we evaluate the performance oftwo on-demand reactive routing protocols i.e., AODV andDSR under TCP NEWRENO traffic. The simulations areperformed using NS-2.34 simulator and the final resultsindicate that AODV outperforms DSR when the

performance metrics like Average end-to-end delay andThroughput are considered. DSR transcends AODV ifpacket delivery ratio is considered.Index Terms: AODV, DSR, MANET.References: I.

However, optimization of the wireless network

performance is of paramount importance. To solve this issue,several variants of TCP congestion control algorithms havebeen already proposed. However if one looks more carefully,a congestion control algorithm is proved to be efficientdepending on the network topology it is being applied to. Inthis paper, we have considered a congested network andcompared performance efficiencies of Reno, New Reno andSACK by observing fast retransmit, fast recovery andretransmission timeout mechanism and throughput results.We observe that New Reno performs best in optimisingperformance in case of increased number of nodes.Index Terms: Traffic control, information rate, wirelessLANReferences:

Queuing isone of the vital mechanisms in traffic management System.Each router in the network must implement some queuingtechniques that governs how packets are buffered while waitingto be transmitted. There are many queuing techniques likeWFQ (Weighted Fair Queuing), Priority Queuing and FairQueuing . This paper gives a comparative analysis of WFQ(Weighted Fair Queuing) and priority queuing. The study hasbeen carried out on end to end delay, jitter, and throughput byusing OPNET Simulator. The simulation results shows that

WFQ technique has lower end to end delay and jitter, maximumthroughput than priority queuing. From this, the WFQ providesbetter performance than the priority queuing in IP networks.Index terms: WFQ, OPNET, Delay, JitterReferences:[1] Liu Tong (Res. Inst. of Commun.

Westwood and HTCP is to be simulated and tested onWLAN network. When packet loss is sensed in the wirelessmedium, HTCP responds with the traditional AIMDalgorithm to resolve the loss and restart the TCP session.HTCP considers packet loss as congestion. However TCPWestwood has special approach to differentiate packet lossover wireless from congestion on wired link. Westwoodestimates available bandwidth when packet loss hasencountered based on the receivedacknowledgement .Hence Westwood adjusts congestionwindow and slow start threshold which promotes fasterrecovery and reliable congestion avoidance. This techniqueenhances adaptability over WLAN. With regards tothroughput performance and adaptability over wireless

media, Westwood yields better than HTCP.Index Terms: congestion window, TCP Westwood, TCPHTCP, wireless LANReferences:[1] M.

integral services, such as voice service, should be tested at alltiers of IP infrastructure. In this paper we will take a new look athow VoIP service behaves at multiple connection speeds, andwhat factors interrelate while we switch between differentconnection speeds. The network model will carry in it all aspectsof traditional VoIP service in coexistence with normal IP traffic.The results will focus on how jitter and packet loss must beminimized. The conclusive idea behind the work is to definesolution for jitter and packet loss optimization in terms of linkspeed mismatch or opportunity, and utilization rather than onlyfocusing on one connection speed, fixed utilization, and zerogrowth factor.Index Terms: VoIP, Bandwidth Optimization, QoSReferences:
