Basavaraj. S. Mathapati, Siddarama R. Patil, V. D. Mytri . An Adaptive Energy Efficient Forwarding Data Aggregation and QoS Protocol for Wireless Sensor Networks. International Journal of Computer Applications. 46, 20 ( May 2012), 37-45. DOI=10.5120/7060-9817
In this paper, we propose to design an adaptive energy efficient forwarding data aggregation technique for wireless sensor networks. Initially we 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. From our simulation results we prove that this technique is efficient in terms of energy consumption and reliability. We have compared our results with Adaptive Energy Efficient Reliable Routing protocol (AEERRP) and found our results are more energy efficient and reliable then AEERRP by varying Number of Nodes and rates.
