Abstract
According to the random mobility and intermittent connectivity problems in delay tolerant mobile sensor network, the reliable transmission mechanism based on network coding is proposed in this paper. Mainly aiming at the mobility and network coding technique of sensor node in DTMSN, comprehensively considering various factors affecting the quality of service guarantee in DTMSN, the data packet is mapped to network with the cluster as units, and the optimal transmission scheme is determined according to the bit error rate and the relay forwarding node selected by opportunistic. The simulation experiment results demonstrate that compared with the direct transmission and flooding algorithm, the proposed reliable transmission mechanism has better performance in terms of bit error rate, real-time and energy efficiency
