Abstract

A paramount concern in dynamic wireless networks is efficient utilization of limited resources. The dynamic nature of wireless networks makes it difficult to use limited resources in a cost-efficient way. The traditional single-utility model, such as link quality, is inadequate for addressing this problem. In this talk, we discuss a composite utility model and use the routing problem in dynamic wireless networks as its application. Specifically, we integrate cost and link quality into a single network utility metric together with the benefiit of successful delivery of a routing packet to evaluate routing optimality. An efficient algorithm design, both centralized and distributed, is presented. Finally, several extensions to the basic model are discussed.
