The International Telecommunications Union has providedvital statistics on ICT use, which evidently shows an increas-ing trend of universal growth in ICT uptake. Accordingto ITU, in 2013, there are almost as many mobile-cellularsubscriptions as people in the world. This is attributed tothe mobile revolution, which delivers ICT applications ineducation, business, government, banking, health, and so on.Thus, the concept of mobile computing has revolutionizedpeople’s lives such that, nowadays, any information can beaccessed and transmitted anytime and anywhere from anydevice. This new way of interacting with services basicallyhas two main underlying drivers: (1) availability of inno-vative mobile devices (e.g., smartphones and tablets) and(2) emerging ubiquitous and affordable wireless networks.According to IndustryWeek, mobile computing is acceler-ating in organizations as well and mobile technology isviewed as providing the biggest boost to businesses. By 2020,the number of connected devices globally is expected toreach 80 billion and augmented reality facilitated via mobiledevices will penetrate most sectors: leisure, social media,retail, restaurants, property, transport, and so on.

However, mobile computing is also a power-hungry tech-nology.Therefore, there is a pressing need for the deploymentof sustainable mobile computing and communication whichfocus on reduced energy consumption of its mobile ICTinfrastructure and CO2 emissions in order to uphold thethree pillars of sustainability: environmental, economic, andsocial. This is made possible if sustainable mobile computingplatforms appropriately address the following challenges:

extension of battery life, reduction of heat dissipation fromcomponents, power consumption, energy efficient wirelesscommunications, efficient resource management, and sus-tainable power architecture. Some of the energy efficienttechniques in sustainablemobile computing are as follows: (i)hardware: homogenous and heterogeneous multiprocessorsystem-on-chip, integration ofmulticore processors andmul-tiple accelerometers into mobile system-on-chip, context-aware and energy aware operating systems, energy aware vir-tual memory (PAVM), application processor integration, andoptimized scheduling in multiprocessor architectures; (ii)Wi-Fi communication: energy aware cellular data schedulingand energy-delay trade-off and dynamic voltage and fre-quency scaling (DVFS); (iii) sensors: accuracy and energytrade-off; (iv) applications: energy efficient computationoff-loading, multithreaded applications, and green softwaredesign patterns.

The scope of this special issue is in line with recentcontributions from academia and industry on the recentactivities that tackle the technical challenges making mobilecomputing and communications more sustainable. For thecurrent issue, we are pleased to introduce a collection ofpapers covering a range of topics such as frameworks formul-ticore mobile computing; architectures for IoT with mobilefog servers; energy efficient schemes for video streamingon mobile devices; security service chaining solutions forsustainable mobile edge computing; content downloadingtechniques for VANETs.
