Energy-Efficient Data Collection by Mobile Sink in Wireless Sensor Networks

Abstract

This paper is to explore how to enhance the benefits of mobile sink data collection in the wireless sensor network (WSN). Mobile sink moves along a scheduled route to collect data. A shorten traveling salesman problem (TSP) route is explored in this study. Along the resultant route, energy efficiency is achieved for the mobile sink to collect data in a round. Finally, experimental results show that the total energy consumption of mobile sink consumed including the sensor communication and the sink movement distances compared to the existing work can be minimized.
