Using MIMO adaptive transmission for increasing the throughput of a multihop wireless network

This paper investigates the use of MIMO techniques in a multihop wireless network. We consider that the link between any two nodes can be established using one of two different MIMO schemes and one of many modulation orders. Computer simulations were carried out in order to identify the best configuration for different channel conditions. Then, the source-to-destination route, which may be composed of multiple hops, is optimized in order to maximize the data throughput. Simulation results indicate that the adaptive selection of the MIMO technique and the modulation order for each link can considerably increase the data throughput in a multihop network.
