Extensive research has been done on reliable data forwarding in sensor networks. Existing protocols provide reliability at the cost of high energy consumption. In Wireless Sensor Networks (WSN), data aggregation is essentially used to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced. Power consumption is an important aspect to be considered in the data aggregation which is a scarce resource and they are irreplaceable. In this paper, the authors propose to design an energy efficient reliable data aggregation technique for wireless sensor networks. Initially, they form clusters and a Coordinator Node (CN) is selected near the cluster in order to monitor the nodes in the cluster.
