Abstract— Network coding technique increases wireless net-work communication efﬁciency. Wireless multihop relay network has been shown to achieve capacity gain over con-ventional single-hop wireless networks. Hybrid wireless relay networks integrate multihop ad hoc relay and infrastructure base stations to achieve better wireless network perfor¬mance. Applying the promising network coding technique to hybrid wireless relay networks could increase wireless net¬work capacity. Capacity of multihop cellular network with network coding is derived. To enhance network throughput, data forwarding strategy is proposed to determine if a packet should be transmitted through intra-cell ad hoc relay, inter-cell ad hoc relay, or infrastructure-assisted inter-cell transmission.
