Dynamic Sink Assignment for Efficient Energy Consumption in Wireless Sensor Networks

Free registration required

Executive Summary

Efficient energy consumption is a challenging problem in Wireless Sensor Networks (WSNs) and closely related to extending network lifetime. The usual way of tackling this issue for topologies with fixed link weight and fixed sink location, has been shown to be severely affected by the energy hole problem. In this paper, the energy consumption problem is initially studied for WSNs with fixed sink assignment and it is analytically shown that energy consumption is minimized when the sink is assigned to the node that is the solution of a suitably formulated 1- median problem.
