| 摘 要： | 就无线传感器网络中的能量利用效率和负载平衡问题进行了研究,提出了一种基于环的非均匀分簇路由协议(NRCR)。在该协议中,节点分布在相同间隔的同心圆环中。通过最优化的簇头数目,同心圆环被分为不同大小的网格,由网格来组成簇。同时根据剩余能量和节点的位置选择簇头。最后,通过旋转网格改变节点的相对位置来平衡网络负载。仿真结果表明NRCR能有效均衡节点之间的能量消耗,延长网络寿命。

| Abstract: | The energy efficiency and load-balancing problem in wireless sensor networks(WSN)are conerned.Non-uniform ring-based clustering routing protocol(NRCR)is proposed.Nodes are distributed in concentric region with the same interval.According to optimal number of cluster heads,the rings are divided into grids of different size and grids compose of clusters.Depend on residual energy and node location to select cluster heads and rotate the grids to change the location of nodes.Simulation results show NRCR effectiv... |
