无线传感器网络中基于移动代理的信息驱动的多分辨率算法研究

该文提出了一种适用于无线传感器网络的基于移动代理的信息驱动的多分辨率(MAIDM)算法，以提高目标跟踪过程中数据处理的精度和容错性，并满足无线传感器网络对节能方面的要求。该文在以簇为逻辑结构的无线传感器网络中，移动代理根据各节点信息贡献量的估计,使用多分辨率算法收集、处理节点数据，并根据移动代理迁移路径上节点信息贡献量的最大值，动态决定其携带的数据量，以达到在节省能量的同时，提高跟踪的精度和容错性。仿真验证了MAIDM算法在精度和容错性方面比IDSQ算法有很大的提高，在节省能量方面比MA-CSIP算法更加有效。

Study of Mobile-Agent-Based Information-Driven Multiresolution Algorithm in Wireless Sensor Networks

in this paper, Mobile-Agent-based Information-Driven Multiresolution Algorithm (MAIDM) is presented for Target Tracking in Wireless Sensor Networks(WSN), in order to provide better accuracy and degree of fault tolerance while meeting the energy requirement. In a clustered-based wireless sensor networks，mobile agent is used to process data of nodes with multiresolution algorithm according to information contribution of different nodes，and the size of mobile agent is determined by the maximum value of the information contribution along the path of mobile agent. A balance has to be struck between the energy efficiency object and fault tolerance/accuracy object. Simulation results show that MAIDM performs better than IDSQ from perspectives of fault tolerance and accuracy, MAIDM s energy-efficient performance is better than MA-CSIP.
