Overlapping-node removal algorithm considering the sensing coverage of the node in WSN

Abstract

In this paper, we propose Overlapping-node Removal Algorithm that utilizes the backup node to the detection of the nodes in the WSN sensing coverage overlapping node. Overlapping sensing coverage of the node that has a data network, energy efficiency is very low. In the proposed algorithm, the initial network connection each node to know the location information of neighbor nodes within their communication coverage, because according to the radius of the sensing coverage overlapping node may be able to identify. Overlapping node that occurs during the network tasks is changed to the standby-node until a specific event occurs, replace the fault node can improve the network lifetime. © 2013 Springer Science+Business Media.
