【摘要】 针对无线传感器网络能量受限和多跳路由的特点,将蚁群系统原理用于网络的广播和数据聚集中,提出并仿真实现了一种能够最小化传感器网络的总能耗算法.理论分析和仿真数据表明,基于启发式蚁群系统的算法,能够较快的收敛,并找到最优解或是近优解;在网络节点数不同(10~50)的情况下,该算法的单次广播能耗和通信距离比现有的两种主流广播协议算法分别减少了20%~60%和14%~20%,因此其网络生存时间增加了10%~100%,表明该算法总体性能优于传统算法.更多还原

【Abstract】 The wireless sensor network has the characteristics of power-constrained and multihop routing.The paper present an energy-efficient algorithm for data broadcasting and gathering in the sensor networks.The main goal is to minimize the whole energy consumption.Simulation results show that the presented algorithm can effectively solve the problem,consumes only 20%-60% transmission power compared to that of the traditional algorithms,so prolongs 10%-100% network lifetime under the cases of different seneor numbers(10-50).更多还原
