This workshop focuses on models and techniques for addressing resource allocation problems in wireless networks. Resource management in wireless environments is extremely complex due to the specific characteristics of wireless communications, such as user mobility, interference, the intrinsically scarce bandwidth, and the highly variable and unpredictable propagation conditions. These features present a vast range of novel and fundamental challenges as wireless networks evolve to support an expanding variety of data applications. In particular, data streams have drastically different traffic characteristics and Quality-of-Service requirements from voice services, urging a radical overhaul of voice-centric air-interface and resource allocation paradigms. In addition, existing congestion control protocols for data flows like TCP were originally designed for wire-line networks, and are not well-suited to wireless links which are inherently slow and error-prone. A further dimension of complexity stems from the growing diversity in network architectures, as wireless LAN's and ad hoc networks rapidly proliferate, giving rise to a wide spectrum of pricing and routing issues.
