Collaborating Using Intergroup Communications in Group-Based Wireless Sensor Networks: Another Way for Saving Energy

[EN] 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.This work is supported by the “Ministerio de Ciencia e Innovación”, through the “Plan Nacional de I+D+i 2008-2011”, project TEC2011-27516 and by the “Universitat Politècnica de Valencia” PAID-00-11.García Pineda, M.; Bri Molinero, D.; Lloret, J.; Lorenz, P.
