| 摘 要： | 针对无线传感网在环境监测应用中节点能量的问题,基于PEGASIS算法设计了一种改进的路由算法PBRE。该算法采用了改进的距离门限策略(短链聚合策略),并在簇头选举过程中综合考虑了节点发送数据的能耗和剩余能量。实验表明,该算法在延长网络生存时间和数据传输时效性上的有效性,且具有一定程度上的避障功能。

| Abstract: | A new routing algorithm for environmental monitoring called PBRE, which is based on PEGASIS proto col, is proposed in this paper. The new algorithm uses an improved distance threshold means. It also adopts the re maining energy levels of nodes and the energy consumption to decide which nodes is qualified to be the LEADERS of the chains. The simulation results show that the proposed algorithm can prolong the network lifetime and provide shorter delay in the process of data transmitted compared to PEGASIS. Besides, PBRE algorithm has a certain de gree of obstacle avoidance function in some specific application scenarios. |
