Abstract

This chapter provides a comprehensive review of the architectures, algorithms, and protocols in the topic of resource management in IEEE 802.11-based wireless networks such as wireless LANs, heterogeneous wired/wireless networks, mobile ad hoc networks, and wireless mesh networks. The focus is given to the approaches for bandwidth allocation in different networks as well as how these strategies are incorporated in each specific protocol. Although the issues of resource management and quality of service support in different networks highly depend on the specific network architectures and mobility patterns, existing works in the literature have shown that the key issue in 802.11 networks is how to coordinate the contention based channel access by considering channel rates, network topology, interference, and mobility. With successful resource allocation schemes, sufficient quality of services can be supported to maximize user experiences with multimedia applications such as voice and video in wireless networks.
