In wireless sensor network energy is a scarce resource. Concentration of data traffic towards sink causes nearbynodes to deplete their batteries quicker than other nodes, and leaves sink stranded. This problem can be solved by keepingthe sink node mobile. Mobile sink saves more energy compared to stationary sink node by moving and collecting informationfrom the field. Existing literature is defined for single mobile sink. Network lifetime can be further increased by multiplemobile sinks in the sensor field. In our proposed work we address this problem for multiple mobile sink. Rendezvous nodesare selected by set covering problem that stores the packets on behalf of network before forwarding to sink at nearestrendezvous point. Sensor network is divided in form of circles that forms the path for mobile sinks. Our scheme increasesenergy efficiency by reducing hops for forwarding packets. We have also proposed rendezvous node rotation to avoid overutilization of rendezvous nodes. Mathematical formulation is also defined and simulation results are compared withstationary sink and multiple stationary sink. Performance parameters considered are energy efficiency, network lifetime,number of dead nodes and packet drops.
