Optimized Multi-Antenna Communication in Ad-Hoc Networks With Opportunistic Routing

Free registration required

Executive Summary

The authors consider the problem of using multiple antennas to maximize end-to-end performance in a multi-hop ad hoc wireless network with opportunistic routing. They find that when a single data stream is sent per-hop, performance is maximized by aggressively increasing spatial reuse, as opposed to increasing per-hop length or rate. They also show that using spatial multiplexing to transmit multiple streams per hop results in a linear increase in performance with antennas, even with fixed spatial reuse, and is generally superior to sending only a single stream.
