Abstract :
This paper presents a pipelined prototype for a planned 2.4 GHz wireless MIMO mesh network. The prototype design and channel allocation method are investigated in detail. MIMO´s interference cancellation algorithm and MIMO-MU model are used to allow more parallel streams at one time, which greatly improves the throughput both for UDP and TCP transmission. The three non-overlapped channels are all used in this prototype. Channel 1 and 11 are assigned to backbones of mesh network and channel 6 is assigned to the connections between wireless clients and router. Simulation results by NS2 are analyzed at the end of this paper. Comparing with normal multi-channel-multi-interface mesh networks, the average throughput improves by more than 80% and 200%, while the packet delay is reduced by approximately 50% and 70% for 2-hop and 4-hop scenarios respectively
