The dual-hop truncated ARQ (DHT-ARQ) and multiple relays cooperative truncated ARQ (MRCT-ARQ) with relay selection in wireless sensor networks are analytically analyzed in this paper. A three-state discrete time Markov chain method is proposed, which is then used to derive the steady state distribution and throughput expressions. Furthermore, the number of retransmission of the two protocols is truncated, and the average packet transmission delay is solved. Finally, considering the power consumptions of source node, relay node and destination node, the energy efficiency expressions are obtained. Numerical simulation results show that the throughput and delay performance of the latter is better than the former. When the channel environment becomes poor, using the DHT-ARQ protocol is more advantageous to reduce system overhead.
