| Abstract | This paper presents an efficient ARQ protocol, called WO-RANC, to enhance coverage and performance of IEEE 802.11p. WO-RANC exploits relay-assisted network coding and work-based wide-sense opportunistic retransmission. Relay nodes with strong connectivity to destinations opportunistically deliver information to the destinations on behalf of sources, thus enhancing coverage and performance. To minimize redundant retransmissions due to loss of per-packet ACKs and avoid relays from transmitting non-innovative packets, both sources and relays combine packets stored in their buffers for transmission, rather than store and forward. In addition, WO-RANC uses the concept of work to accurately estimate the information deficiency that destination nodes do not received due to failed transmissions. And accordingly, relay nodes transmit packets to supplement the information deficiency. Our simulation results show that WORANC outperforms 802.11p and several other schemes in terms of throughput and delay, for a large range of source-destination distances. Keywords—ARQ, opportunistic retransmission, network coding, wireless network, vehicular network. |
