应用移动Agent的无线传感器网络能量管理机制

鉴于无线传感器网络能源受限的显著特征,有必要讨论其有效的能量管理机制。目前,大多数研究成果仅考虑到拓扑控制、路由、数据融合等某一方面的节能问题,往往缺乏对网络活动整体能耗的测控,因而缺乏完整性。本文应用移动Agent技术,从多个角度探讨了传感器网络的节能问题,包括拓扑和簇的生成、数据采集等。提出了若干基于移动A-gent的能量管理算法,并通过仿真实验和算法性能比较,立足于平均能耗、通信流量和负载、网络生命周期等几个方面,分别总结了其优缺点及可行性。

A Power Management Mechanism for Wireless Sensor Networks Used by Mobile Agents

Aimed at the remarkable characteristics of power restriction on wireless sensor networks, it is essential to resolve the issue on effective power management. Currently,plenty of research work runs short of integrity because it only considers power saving from one of the following techniques such as the topology control mechanism, the rooting protocol or the data aggregation algorithm, but not to measure the power consumption of the whole network. With the introduction of mobile agents, it discusses the power management of the sensor networks from several points such as topology control and cluster forming, and data collection. Some novel algorithms based on mobile agents for power management are proposed. Based on simulation and  performance analysis on power consumption, balancing the communication flows and the whole networks’ life span, it analyzes the advantages, disadvantages and feasibility of these algorithms.
