Delay Management in Wireless Ad Hoc Networks

A good amount of research has been developed to support QoS issues in IEEE 802.11 ad hoc networks. In this chapter, we address QoS management issues through multiple layers for real-time multimedia applications. We investigate the adaptation mechanisms at middleware layer and MAC layer to dynamically adjust the service classes for applications by feedback control theory. Based on our investigation, we propose a cross-layer end-to-end delay management framework for multimedia traffic over multi-hop wireless networks.
