In wireless sensor networks, sensors are used to detect abnormal event and report the sensed data to the sink. Sensors have limited power resources. Sensor nodes deliver sensed data back to the sink. The sensor nodes near the sink will consume more battery power than others sensor nodes, the node will quickly drain out their battery energy and Shorten the network lifetime of the wireless sensor network. Mobile sink based data collection is an efficient network lifetime extension method. Divide the network into multiple clusters by using clustering algorithm. Each cluster has one Cluster Head (CH). Cluster head are responsible for collecting data from their node.
