Abstract：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.
