无线传感器网络中基于树的能量高效分布式精确数据收集算法
A Distributed Tree-Based Energy-Efficient Algorithm for Precise Data Gathering in Wireless Sensor Networks
摘要
Abstract
In this paper ,we propose a distributed tree-based algorithm for precise data gathering in wireless sensor networks called EEDAT ,which achieves longer network lifetime than existing distributed algorithms .The EEDAT algorithm has two steps .In the first step ,a shortest path tree is constructed in a distributed manner .In the second step ,EEDAT adjusts the load of nodes in the generated tree to balance energy consumption of different nodes ,which effectively extends the lifetime of the network .In the adjust-ment ,both the number of children of a node and its residual energy are considered .Simulation results show that EEDAT achieves longer lifetime than the LMST algorithm .On average ,compared with LMST ,EEDAT prolongs the lifetime by 20% .关键词
