Flow control is a mechanism for resource allocation, but in wireless networks we also have to consider power control and scheduling as part of the overall resource allocation problem. In fact, since optimal routes depend on interference, all layers interact, and a cross-layer design process is required. At the physical layer are issues such as power control, MIMO technology (interference suppression and beamforming), and space-time coding. At higher layers there are medium access control, routing, and flow control. In this new project we take a joint approach to flow control, routing, scheduling and power control using methods from optimization and control theory. Part of the project is concerned with the design of higher-layer control protocols for these networks such that the network reaches an equilibrium dictated by the optimality criteria. An aspect of the project is a collaboration with physical layer researchers working on polarization diversity. Polarization diversity can be exploited in rural environments when other forms of diversity are not present. In Australia, there is particular interest in the problem of "broadband to the bush" and we believe that multihop wireless mesh networks may play an important role in helping with this problem. A key research problem is to determine the optimal point on the rate diversity tradeoff curve for each link in the network to provide reliable service from an end-end perspective. Scheduling, routing and flow control are clearly important issues to be addressed.
