Improving Throughput Using MIMO-Based Routing Protocol with Multi-Links and Antenna-Selection

It is a big challenge to exploit multiple antennas for routing protocol design in ad hoc networks. In order to improve throughput in the networks, this paper proposes a newly designed self-adaptive source routing (MISR) protocol based on multi-links especially including the Group-MUX link with antenna selection scheme that could achieve both the multiplexing and diversity gains simultaneously. Through the detailed analysis and simulation results, it is proved that MISR protocol would have a distinct capability to handle the heavy business load, and greatly contribute to the aggregate throughput and end-to-end delay in Ad Hoc networks.
