For large-scale wireless sensor networks via multi-hop transmission for data collection,and cause for the energy hole problem,this paper presents a mobile Sink based rendevous data gethering( MSRDG) algorithm. The algorithm is based on graph theory to meet the conditions of delay. Considering the common nodes to the cluster head node routing and mobile Sink traversing path selection problem,a mobile trajectory is composed through a cluster head nodes as much as possible. Through the NS-2 simulation software to evaluate performance of the algorithm,results show that the proposed algorithm can reduce multiple hops of the data transfer and the energy consumption of wireless sensor network node,and prolong the life of the network.
