Cluster cooperation for energy saving in wireless personal networks

Recent years have witnessed an explosive growth of wireless technologies and applications. Without disruptive new approaches for energy saving, 4G mobile users will relentlessly be searching for power outlets rather than network access, and become once again bound to a single location. In this paper, we explore the cooperation among nodes in a cluster for the main goal of saving the battery power of mobile terminals. This paper studies the possibility of decreasing energy consumption through relaying data from all nodes in a cluster through the cluster head. Simulation results are presented from a scenario composed of nodes supporting both UWB (among them) and WiFi communications to an AP. Results demonstrate the gains in energy saving and the benefits incurred to QoS requirements, namely throughput and packet delay. The work also guarantees that the required QoS is always maintained.
