Objective Literature Survey Issues IdentifiedProposed systemIntroduction to wireless overlay networkHandoffE-UTRANExpected results References

To investigate the performance degradation factors in heterogeneous wireless networks and improve it by using proposed work.

To determine time at which multimode terminal should initiate a handoff in wireless overlay networks.

To minimize packet loss and Improve Qos by reducing the number of vertical hand off.

To provide seamless connectivity for Multimode Terminal in overlay network using effective handoff decision algorithm

“Algorithmic Vertical Handoff Decision and Merit Network Selection across Heterogeneous Wireless Networks” by Sunisa gunarak and Raungrong suleesathira, WSEAS Transaction on Communication,Issue 1,Vol 12 January 2013.

It explains the multiple metrics for handoff to permit connectivity across UMTS and WiMAX/ WLAN. But the considered metrics for handoff initiation include the predicted received signal strength of neighbourn network

“A QOS oriented vertical handoff scheme for Wimax/WLAN overlay network” by Dong Ma and Maoda Ma ,IEEE transactions on parallel and Distributed systems April 2012.

It explains the internetworking architecture of WiMAX and WLAN and also architecture based proactive vertical handoff, but it depend on network condition and applications.

“overlays with preferences: Approximation Algorithms for matching with preference list” by Giorgos georgiadis and marina papatriantafilou –IEEE 2010/978-1-4244-6443/10.

It employ the use of node satisfaction to move beyond classic stable matchings and toward the overlay context and total satisfaction achieved by approximation of possible connection in overlay.

Proposed algorithm effectively alleviating the unnecessary vertical handover between 3G cellular and WLAN hotspots and compute threshold value based on received signal strength Which is non linear .

Overhead in vertical handoff is high due to different network posses

different system architecture, bandwidth, latency and capacity

Due to the inconsistent Characteristics of wireless communication

environment, Received signal strength to MT cannot be linear,in such

cases VHO is not executed properly.

Interoprability problems between advance cellular network like

E-UTRAN and exist WiMAX/WLAN not investigated.

Proposed algorithm provide best Qos oriented vertical hand off scheme for E-UTRA and WiMAX /WLAN overlay networks.

Investigate several important issues for the interoperability of E-UTRAN and WiMAX/WLAN networks.

To determine time at which terminal should initiate a handoff in

heterogeneous overlay network.

Packet multicasting technique used to prevent packet loss during handoff.

It provide dynamic many -to-many connectivity between set of senders and group of receivers.

A wireless overlay network is a virtual network of

nodes and logical links that is built on top of existing network

For routing

For security

For addressing

For multicast

For mobility

Process of maintaining active connection to mobile nodes

Horizontal handoff - occur in same network(homogeneous network)

Vertical hand off -occur between different network(heterogeneous network)

System discovery

Vertical handoff decision

Vertical hand off execution

E-UTRAN- Evolved universal terrestrial radio network

E-UTRA is the air interface of 3GPP Long Term Evolution (LTE) upgrade path for mobile network.

It provides higher data rates, lower latency and is optimized for packet data.

It uses OFDMA radio-access for the downlink and SC- FDMA on the uplink.
