摘要： 提出并实现一种基于地理区域划分的多基站局部移动的能量均衡路由算法(RPEB)。该算法基于多基站区域划分方法实现节点的“伪非均匀”分布，即在密度相等的条件下，越靠近基站，节点数量越多，从而达到能量均衡的目的，避免节点密度高所导致的冲突。在Micaz节点搭建的实验平台上实现RPEB算法，实验结果表明，该算法有效延长了网络生命周期，提高数据送达率。

Abstract: This paper proposes and implements a Region-Partition and Energy-Balanced routing algorithm(RPEB). It achieves the result of regional motes pseudo-non-uniform by region-partition, that is, under condition of equal density, the nearer the base station there are more motes. This algorithm can achieve the purpose of energy balance and avoid conflicting caused by dense motes. It implements RPEB on the test bed of Berkeley Micaz sensor motes. Experimental results show that RPEB prolongs remarkably the network lifetime and improves data service.
