IEEE 802.16j is to enable the operation of multi-hop Relay Stations (RS). It aims to enhance the coverage, per user throughput and system capacity of IEEE 802.16e. However, the Mobile Stations (MSs) which connect to the RS are suffered from exponentially throughput degradation and end-to-end delay increase in congested network. As the number of RS hops increase, so does the degradation and the delay growth, especially on over 3 hops scenarios. This paper proposes a network coding-based relay scheme for multi-hop relay networks, called NC-based relay.
