Device-to-Device (D2D) communication enables direct communication between nearby user devices using cellular or ad hoc links thereby improving the spectrum utilization, system throughput, and energy efficiency of the network. Exploiting mobile cloud based D2D communication architecture underlying LTE cellular network has a huge importance in reducing the transmission power of the UEs resulting an...
As the wireless industry evolves towards heterogeneous networks, mobile terminals have been given the ability to handover from one network to another. The network selection process starts by a network discovery operation which involves scanning the candidate networks in order to collect the required information for handover decision. Such operation consumes a considerable amount of energy at the terminal-end...
Wearable devices are becoming increasingly popular and are expected to become essential in our everyday life. Despite continuous improvement of hardware, the lifetime of mobile devices and their capabilities still remain a concern. Small size of batteries of smart watches, glasses, helmets and gloves limits the amount of computing, storage and communication resources. Mobile cloud computing can augment...
The Point Coordination Function (PCF) of the IEEE 802.11 standard represents a well-known Medium Access Control (MAC) protocol providing Quality-of Service guarantees in Wireless Local Area Networks (WLANs). However, with the currently employed polling mechanism WLANs consume a significant amount of the energy resources from battery-powered user devices. To provide energy saving, an improved MAC protocol...
