Abstract
In order to solve ‘hot ’ issue in Wireless Sensor Network ( WSN ) and to avoid the network premature invalidation caused by local emergency,an energy-efficient routing algorithm with mobile node for WSN is proposed in this paper. To save energy consumption,the network is divided into several square virtual grids in this algorithm,a cluster head is selected by weighted sum of the residual energy of node and the distance of the node to the areal coordinate,and the sink node receives data from the cluster head by controllable moving scheduling strategy. Moreover, to extend the network lifetime,unlimited energy mobile relay is introduced,and is in the service of information transmitting large area. Influence of two parameters,the movement speed of the sink node and the weighting coefficient,on the performance of the proposed algorithm is detailed analyzed by simulation. The results show that the lifetime of the network, the total energy consumption and the total amount of data the sink node receives of the proposed algorithm are better than MSEERP and TTDD algorithm. When the movement speed of the sink node is equal to 5 m/s,the weighting coefficient is 0. 6,and the performance of the proposed algorithm is best.关键词
