Energy Efficient Strategies in Wireless Sensor Networks with Mobile Sink

Abstract

In this paper we present an overview of energy efficient strategies in wireless sensor networks (WSNs) with mobile sink. Firstly, we investigate the existing issues in WSNs. Then we focus on the problem of energy efficient data gathering strategy with mobile sink and present some existing solutions. Finally, we conclude this paper with some potential extensions which need to be further explored. Through the existing works, we can see that sink mobility can enhance the network performance.
