An energy efficient rendezvous node selection approach

Using a drone as a mobile sink is an interesting issue in wireless sensor networks. There are many studies that try to minimize the flight distance of the drone but their approaches causes unbalanced energy consumption of nodes. In this paper, we propose a new rendezvous node selection approach to achieve the balance of each node's energy consumption and to minimize the flight distance of the drones. Simulation results show that our approach can extend the entire network life-time and maintain the stable variation of the flight distance.
