Energy-Efficient Data Collection by Mobile Sink in Wireless Sensor Networks
Tzung-Shi Chen, Wei-Qing Du, Jen‐Jee Chen · 2019
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.
