Efficient Multi-path Routing Protocols in Wireless Sensor Networks

Small-sized, cheap, and power-limited sensors that possess sensing, signal processing and wireless communication capabilities is becoming popular for the wireless sensor networks. Due to the limited resources and energy constraints, efficient routing algorithms should be employed in sensor networks. In this paper, we propose a node-disjoint multi-path hexagon-based routing algorithm. We divide the given messages into 4 segments, which are routed to 4 node-disjoint routes using hexagon-based networks. We describe the details of the algorithm and compare it with other schemes. Simulation results show that the proposed scheme achieves better performance in terms of message delivery ratio and network life time.
