摘要
提出一种基于元胞自动机理论的同构无线传感网络生命周期仿真模型.在分析传感器网络主要属性、部署方式、能量消耗模型、拓扑结构与通信以及休眠/唤醒机制等因素的基础上,该模型首先给出了同构无线传感网络的元胞自动机表示方法,然后定义了同构无线传感网络动态演化过程中的能量更新规则和状态更新规则.试验表明,该模型能够对同构无线传感网络的整个生命周期内传感器状态变化、网络覆盖与拓扑变化以及网络的运行周期进行有效仿真.
A simulation model for an isomorphic wireless sensor network life cycle has been proposed.Firstly,based on an analysis about main properties of sensor and deployment of network,this paper describes how to represent an isomorphic wireless sensor network by using a cellular automata.Then,according to energy consumption,topology control,communication route and sleep/wake-up mechanism,energy updating rule and state updating rule have been defined,which are used to control the evolution process of an isomorphic wireless sensor network during its life cycle.Experimental results show that this model can simulate the state and energy change of each sensor,the coverage and topology change of a network,as well as the whole life cycle of an isomorphic wireless sensor network.
