Wireless sensor networks are highly distributed of small, lightweight wireless nodes. In wireless sensor network, the sensor nodes are distributed in various geographical dispersed areas for sensing the data and the sink node is used to collect data from different sensor nodes, therefore data collection is important issue in wireless sensor network. Every node in sensor network consist of three subsystem, first sensor subsystem which sense environment, second processing subsystem which perform local computation on sensed data and third communication subsystem which is responsible for message exchange. Various Studies in this field exploit that mobile sink node is used to collect environmental observations such as weather forecasting data from sensor nodes.
