Silence Is Golden with High Probability: Maintaining a Connected Backbone in Wireless Sensor Networks
Paolo Santi, Janoš Šimon · Lecture notes in computer science · 2004
Reducing node energy consumption to extend network lifetime is a vital requirement in wireless sensor networks. In this paper, we present and analyze the energy consumption of a class of cell-based energy conservation protocols. The goal of our protocols is to alternately turn off/on the transceivers of the nodes, while maintaining a connected backbone of active nodes. The protocols presented in this paper are shown to be optimal, in the sense that they extend the network lifetime by a factor which is proportional to the node density. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
