An Algorithm for Dynamic Routing Based on Multi-paths in Wireless Sensor Networks

According to the traditional network routing mechanisms, the path with the minimal hops is often chosen to transmit data from source node to destination node. However, frequent communication requests along one path in wireless sensor network result a fact that the nodes on the path prematurely fail with itspsila energy exhaustion. In this paper, a routing algorithm based on the multi-path mechanism is proposed, its main idea is to find multi-paths from source node to sink node, then a path the maximized minimal remaining node energy to choose to transmit data. Compared to single-path routing algorithm, the proposed routing algorithm improves the networkspsila performance on the nodespsila life time and the data transmission.
