摘要
无线传感器网络是一种全新的信息获取和处理技术,路由协议是其组网的基础,在综合大量路由协议和算法文献的基础上,提出了一种新的无线传感器网络路由算法;在该算法中,信息素的形成不仅考虑节点间的梯度因素,还融合了节点的剩余能量,同时,算法中还设置了节点的能量阈值,以防止一些节点由于作为中间节点转发数据包过早死亡而导致这些节点所在区域失去监控;实验结果验证了该算法的有效性,可以很好地适应无线传感器网络无集中控制和动态拓扑的特点,同时支持多径路由。
Wireless sensor network （WSN） is a novel technology about acquiring and processing information. Routing protocol is the base of networking. Based on the analysis of a great deal of recent technical reports and research results on WSN, the paper put forward a new wireless sensor network routing algorithm. In the algorithm, the formation of the pheromone not only considers the gradient factors among nodes, but also integrates with the residual energy of the node. Meanwhile, the energy threshold of node is also set to prevent that because some nodes transmit data packets as intermediate nodes and die early, which lead to lose control in the region. The test proves that the algorithm is available. The algorithm adapts to the character of WSN for non--centralized control and dynamic topology and it supports the routing of many paths.
