Single sink position in wireless sensor networks

Abstract

In a wireless sensor network, the sensor nodes collect information from the environment where they are deployed and send it to the base station, also called the sink, to be delivered to the end user. Many metrics such as the latency of communications and the energy consumption can be affected by the position of the sink. This position should be found before exploiting the network and routing information. In this paper, we propose two sink placement techniques in a wireless sensor network using the position of the other nodes in the network in order to minimize the latency of communication and the energy consumption. The computed position of the sink is as close as possible to every node of the network. Simulation results show that the average latency of communication and the average energy consumption of both proposed sink placement techniques are better than similar works existing in the literature.
