The major driver for deploying next generation wireless cellular systems is their ability to efficiently deliver resource-demanding services, many of which require symmetric communication between an uplink mobile user and a downlink mobile user that belong to the same network. In this work, we propose a utility-based joint uplink/downlink scheduling(More)
A single bit transmission over the wireless card can consume 1000 times more energy as compared to a 32-bit CPU computation. This fact is very critical for devices operating on limited battery such as mobile devices. In this work, we propose a new approach that utilizes a lightweight compression scheme for the to-be-transmitted data in an adaptive manner.(More)
Wireless cellular networks are required to meet the stringent QoS requirements of emerging data services. To efficiently utilize the available radio resources, we propose a new resource allocation algorithm for services that require end-to-end guarantees. Unlike existing literature that mainly focuses on downlink only or uplink only scheduling algorithms,(More)

The proposed scheme monitors the signal strength level during the file transfer process and compresses(More)
A game theoretical formulation for energy minimization in mobile-to-mobile cooperative networks is provided. The problem is formulated as a Nash bargaining game, and the Nash bargaining solution is derived. Furthermore, a low complexity utility minimization algorithm is presented. Using the appropriate utilities, the proposed algorithm is used to implement(More)
Smartphones are evolving at a fast rate in terms of their computational, storage, and communications capabilities. A high-end smartphone is equipped with multiple wireless interfaces with varying bit rates, energy consumption requirements, and coverage ranges. The joint utilization of the existing wireless interfaces facilitates the development of advanced(More)
