Mobile Sensor Swapping for Network Lifetime Improvement

Abstract

Extending network lifetime is a big challenge to WSN. Energy saving is very important to improve the network lifetime. Sensor nodes closer to the sink always consume more energy than nodes away from the sink. In this paper, we consider adaptive energy threshold algorithm and energy level algorithm for Mobile Sensor Swapping. In this approach we swap the positions of sensors which consume more energy with the sensors having low energy consumption. So we can use this approach to extend network lifetime as well as to balance the energy consumption among the sensors.
