Joint bandwidth allocation, element assignment and scheduling for wireless mesh networks with MIMO links
With the unique features of spatial multiplexing and interference suppression, Multiple Input Multiple Output (MIMO) techniques have great potential in the improvement of network capacity over conventional antenna technologies. In order to exploit the benefit of simultaneous transmissions provided by MIMO, researchers have proposed a number of cross-layer optimizations and MAC layer designs to increase the throughput of wireless mesh or ad hoc networks, where the number of elements in the antenna arrays are preallocated or evenly assigned to the routers. In this paper, we argue that using the same number of elements in each antenna array in all routers is not a necessary condition for the improvement of system performance. This is because the requirement for the number of elements is quite different for each router. Especially at those critical routers that have huge aggregate traffic toward the gateway, more elements are needed not only for the traffic relay but also for the interfer...
