In Wireless Sensor Network (WSN), data gathering causes more energy consumption. Also most of the existing literature work on data gathering process considers only distance and node density and skips reliability criteria. Hence in order to offer both reliability and energy efficiency, in this paper, the authors propose to design a mobile sink based reliable and energy efficient data gathering technique for WSN. In this process, a biased random walk method is used to determine the next position of the sink.
