Abstract—Wireless Sensor nodes carry limited generally irreplaceable power sources. One of the major problems while handling the wireless sensor network is the limited availability of the power for the sensor nodes. Due to this energy constrain the data needs to be managed wisely in order to extend the lifetime of the network. In many scenarios sensor nodes will have to rely on a limited supply of energy. Replacing these energy sources in the field is usually not practicable. At the same time a WSN must operate at least for a given mission time or as long as possible. Hence the lifetime becomes a very important figure of merit evidently energy efficient way of operation of WSN is necessary. In this paper we have used a sink repositioning technique for elongating the network lifetime. This scheme basically finds the optimal location of the sink and the routing pattern to deliver the collected data to the sink. Moreover the sink can be placed anywhere inside the sensing field network. The sink repositioning algorithm has been simulated in the NS-2.32 environment. The X graph was plotted for both static and mobile sink and it was observed that repositioning the sink improves the performance of the wireless Sensor networks as compared to the static sink.
