Congestion-driven Topology Control in Wireless Ad Hoc Networks

Abstract : The increasing popularity of wireless local area networks proves current trends in telecommunication industry with notably a growing need for flexibility and ubiquitous wireless connectivity. The introduction of quality of service (QoS) in these networks is even more complex since their topology and their resources evolve dynamically. With this fast evolution, performances and connectivity of wireless networks radio decreases. In this paper, we propose an approach to control the topology of wireless networks based on continuous QoS metrics performances measurements in 802.11 networks. This consists in ensuring the highest connectivity possible by dynamically selecting a set of dedicated mobile routers to ultimately increase the performance of infrastructure-less wireless ad hoc networks. In order to confine the network overload probability, our scheme features a forced handover technique along with a connection admission control (CAC). Finally, we introduce a QoS scheme to manage heterogeneous traffic requirements by allowing for different traffic priorities.
