Abstract:Multipath routing is essential to overcome the high loss rate in Wireless Sensor Networks(WSNs). Current proposals rely on centralized computation or iterative distributed algorithms and consume large amount of convergence time. Therefore, Exploration Packet-based Multipath Routing(EPMR) is proposed in this paper. EPMR routing first collects local topology information by using the transmission of exploration packets. According to the arrival time of the received exploration packet, the port priority is set, and the node that gives priority to the port priority participates in the route. Once participating in a path, the node will no longer participate in other paths between the source node and the destination node pair, thus ensuring the disjunction between multiple paths. Simulation results show that the proposed EPMR improves the packet transmission success rate and cuts the running time.
