The proposed paper addresses the setback of congestion in wireless sensor networks by introducing a mobile sink to reduce congestion.Moreover, in the considered method data has to voyage a restricted number of hops to arrive at the mobile sink which helps to improve the energy consumption of the sensor nodes.Parameters like packet delay, packet loss and throughput are measured for estimation.Since, congestion sternly affects the performance of wireless sensor networks, it has to be minimized in order to boost the life span of a sensor network.The mobile sink approach used in the planned scheme is very much effective in minimizing the congestion in the sensor network.In this model, the sink is not stationary, but it is mobile.With the use of simulation, the utility of the considered scheme in terms of congestion minimization in wireless sensor network is shown.
