Abstract— In this paper we develop and analyze energyefficient cooperative techniques for multimedia applications over wireless networks. The composite cellular-short-range netw...
Abstract—In this paper, we study the problem of misbehavior detection in wireless networks . A commonly adopted approach is to utilize the broadcast nature of the wireless medium...
One of the main characteristics of wireless ad hoc networks is their node-centric broadcast nature of communication, leading to interferences and spatial contention between adjace...
—Cognitive Radio Networks (CRNs) have recently emerged as a promising technology to improve spectrum utilization by allowing secondary users to dynamically access idle primary ch...
Synchronization of relay nodes is an important and critical issue in exploiting cooperative diversity in wireless networks. In this paper, two asynchronous cooperative diversity s...
