In this paper, the authors propose to design an adaptive energy efficient forwarding 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. The CN selects a Cluster Head (CH) in each cluster based upon the energy level and the distance to the CN. The packets sent by the sensor nodes are aggregated at the CH and transmitted to the CN. The CN measures the loss ratio and compares it with a threshold value of loss ratio. Depending upon this value, the forward node count is incremented or decremented and the cluster size is adaptively changed, ensuring reliability and balanced energy consumption.
