Collaborating using intergroup communications in group-based wireless sensor networks: Another way for saving energy

Abstract

Energy saving is the most important feature in wireless sensor networks (WSN). An energy saving method is to perform a logical grouping of nodes and add collaboration between them. In this paper, we show a method of collaboration between groups based on the communication between neighboring groups. Using this information, the groups will be able to create a collaborative intergroup routing pool tree. This routing pool tree allows collaboration between neighboring groups and also efficient delivery of data from any group to the sink node. This collaborative group-based system has been simulated and we have shown that it increases significantly the lifetime of sensor nodes. © 2012 Springer-Verlag.
