Wireless communication has been going through a rapid transition from the traditional circuit switched voice services to packet switched data services during the past decade. Increasing demand for fast and reliable wireless access anywhere and at any time has stimulated much research in wireless communication. In particular, mobile ad-hoc networks (MANETs) are emerging as a promising technology that offers the possibility of delivering relevant information to any location of the network at any time, in heterogeneous environments. Realizing this potential requires facing many research challenges; MANETs need to self-organize, operate in a distributed asynchronous manner, and be robust with respect to network failures, users’ mobility and resulting changes in the network topology, time-varying traffic types, etc.
Traditional approaches used for fixed wireline networks are often inadequate and a new paradigm more suitable for wireless networks is needed. Moreover, uncertainties in the network, for example, introduced by nodes’ mobility and time-varying channels, call for robust protocols. This requires that the algorithms be able to learn from and adapt to time-varying environments.
The goal of our research group is to study various challenging issues unique to wireless networks and design robust resource allocation algorithms: We are currently investigating the issues in routing in MANETs, power control in the presence of uncertainties rising from network dynamics, and congestion control in the presence of unknown (time-varying) communication delays. Our research is funded by National Science Foundation (NSF), Laboratory for Telecommunication Sciences (LTS) and Army Research Laboratory (ARL).
