Energy-Efficient and Adaptive Algorithms for Constructing Multipath Routing in Wireless Sensor Networks

Abstract : In this paper, we design and implement a k-multipath routing algorithm that allows a given source node send samples of data to a given sink node in a large scale sensor networks. Construction and dynamic selection of alternative routing structures, for the purpose of extending the networks lifetime, while providing a balance between QoS(Quality of Service) requirements and the minimization of the variance of the energy. The proposed multipath routing algorithm tries to keep multipath as node disjoint routes. Our view is that balancing load distribution while meeting acceptable delays for applications can lead to significant power savings. The simulation results demonstrate that our multipath routing algorithm can not only achieve load balancing, but also can be help to prolong the life-span of network, compared with the shortest path routing(single path routing SPR).
