为解决无线传感器网络的路由选择问题,提出了动态扩展路由算法。该算法引入洪泛初始化过程,运用路径动态扩展机制以及失败路径的反馈机制,对扩展出的路径采取不相交多路径算法。从数据传输的可靠性、网络负载平衡、节点能量控制等多个方面优化路由效果。仿真结果表明,该算法在网络穿透率方面提高约10%,明显优于传统的路由算法。

Wireless sensor network is a new technique, and one of hotspot is the design of its routing. To sellect a path for the wireless sensor network, a new algorithm about wireless sensor network routing based on gathering data in sink node is proposed, and its name is ic DEP （Dynam Extend Paths） algorithm. This algorithm involves flooding initialization procedure, dynamic extend paths and feedback mechanism for failure path. However it takes the disjoint multipath algorithm on extend path. The routing effect was described from many ways, i. e. , reliability on data transfer, balance for network load, and control of node energy. The simulation results indicate that the DEP algorithm is better than traditional routing algorithms, and the throughput is improved by about 10%.
