摘　　要：移动Agent(MA)模式是无线传感器网络(WSNs)计算模式之一,相对于C/S模式,MA模式具有很多优点。目前,对MA模式的研究主要从网络能耗、时延、数据冗余等方面进行。提出一种以跳数为标准的网络性能评判方法,通过建立网络模型,将网络数据抽象为数据包的形式,计算出2种模式下网络完成一次任务时所有数据包被转发的次数,推导出跳数公式,并以此对2种模式进行研究。结果表明:MA模式的总跳数主要受融合比例因子影响,但总体上性能优于C/S模式。Mobile agent （ MA ） mode is one of the computing modes of wireless sensor networks （ WSNs ）. Comparing with C/S mode, MA mode has many advantages. At present, MA mode is mainly studied on energy consumption, time delay and data redundancy. A method using hop count as standard is proposed for performance evaluation of WSNs, by establishing network model, network datas are abstracted to data packets style, and calculate transmitting number of all data packets with a network task which is completed under the two modes, then formula of hopcount is derived and study the two modes based on this. Result shows that the total hops of MA mode is mainly affected by the fusion proportion factor, but the overall performance is better than C/S mode.
