A Power Efficient QoS Provisioning Architecture for Wireless Ad Hoc Networks

The work presented in this paper1 focuses on a new approach in provisioning Quality of Service (QoS) in ad hoc wireless networks, aiming at making the best use of ad hoc networking as a candidate technology for next generation wireless networks. Specifically, a cross-layer QoS provisioning architecture for wireless ad hoc networks is introduced and described, based on the integration of the recently proposed service vector concept at the network layer and a delay bounded power efficient scheduling at the data link layer. It is demonstrated through modeling and simulations that this novel architecture can provide considerable performance improvements in terms of both power savings and enhanced QoS granularity in wireless ad hoc networks. Furthermore, the performance of the proposed scheme under various traffic arrival rates and distributions is evaluated.
