摘要：Wireless Sensor Network (WSN) consists of a large number of small sensors with restricted energy.Prolonged network lifespan,scalability,node mobility and load balancing are important needs for several WSN applications.Clustering the sensor nodes is an efficient technique to reach these goals.WSN have the characteristics of topology dynamics because of factors like energy conservation and node movement that leads to Dynamic Load Balanced Clustering Problem (DLBCP).In this paper,Elitism based Random Immigrant Genetic Approach (ERIGA) is proposed to solve DLBCP which adapts to topology dynamics.ERIGA uses the dynamic Genetic Algorithm (GA) components for solving the DLBCP.The performance of load balanced clustering process is enhanced with the help of this dynamic GA.As a result,the ERIGA achieves to elect suitable cluster heads which balances the network load and increases the lifespan of the network.
