【摘要】 分析了无线传感器网络中的分簇路由协议LEACH,针对其簇头分布不均匀、簇头节点能量不足等问题进行了相应地改进,提出了一种新的分簇路由协议LEACH_RD-EB。新的协议中通过区域划分来保证簇头节点在整体区域均匀分布;分配临时ID号、改进簇头选举阀值来选取最优簇头节点等。经过理论分析和仿真实验,证明了改进后的新协议有效地延长了网络的寿命、平缓了网络能量的消耗,具有较好的应用前景。更多还原

【Abstract】 The classic clustering routing protocol of wireless sensor network,LEACH protocol is researched.The uneven distri bution of cluster head nodes in the whole area and the lack of the chosen cluster head nodes energy are improved correspond ingly and a new clustering routing protocol,LEACH-RD-EB protocol is proposed.In the new protocol,the nodes even dis tribution in the whole area is determined through the division of the whole region.The optimal cluster head nodes are select ed through temporary ID number and the improvement of cluster head election threshold.Through theoretical analysis and simulation experiments,the new protocol is proved to extend the life of network effectively,flatten the network energy con sumption and has good application prospect.更多还原
