Executive Summary

Wireless relay network is a low-cost solution for extending the service coverage and increasing the throughput of the conventional single-hop wireless network. By deploying a relay network, a Base Station (BS) can provide services to Subscriber Stations (SSs) through relay links. The functionality of a Relay Station (RS) is simpler than a BS, and RSs only forward packets between SSs, RSs and the BS without too much packet processing. However, current solutions require a RS to store and process the packet before it can determine the destination, and thus introduce extra processing and buffering overheads on the RS. This paper proposes a simple and efficient forwarding scheme which multiplexes bursts to the SSs attached to the same access RS.
