Employing Sink Mobility for Energy Efficient Data Collection in Wireless Sensor Networks

Abstract

Small, low-powered, self-organizing sensor nodes that are widely dispersed throughout the area to be monitored make up a wireless sensor network (WSN). WSN is a highly scalable network that is used for a variety of purposes across a wide region of interest. Since every sensor node has a limited amount of energy, it is much more crucial to minimize the energy depletion of those nodes nearer the sink since they are in the way of data transmission. Additionally, the nearby nodes of the sink would deplete their energy more quickly, resulting in a disconnected network. The nodes around a mobile sink constantly shift, balancing the network's energy usage and extending its lifespan. We assess the impact of sink movement in random walk and predetermined path on network lifetime in wireless sensor networks.
