A Position-Based QoS Routing Scheme for UWB Ad-Hoc Networks
Atef Abdrabou, Weihua Zhuang · 2006 IEEE International Conference on Communications · 2006
Ultra-wideband (UWB) wireless communication is a promising spread spectrum technology that supports very high data rates and provides precise position information of mobile users. In this paper, we present a position-based quality-of-service (QoS) routing scheme for UWB ad-hoc networks. The scheme applies call admission control and temporary bandwidth reservation for discovered routes, taking into consideration the medium access control (MAC) interactions. Via cross-layer design, it exploits UWB advantages by using the position information in routing and bandwidth reservation. Simulation results demonstrate that the proposed routing scheme is effective in end-to-end QoS support.
