Abstract : Energy efficiency is the main challenge of wireless sensor network WSN. Many routing algorithms have been designed to meet the demand. Hierarchical clustering is one of the effective techniques for WSN to reduce the load in the network by data aggregation, thus saving energy. In this approach cluster heads take the responsibility to gather information of different events from its neighbors and send that to the sink node. Thus cluster heads loose its energy very early, which causes selection of new cluster head before starting of every round. This paper presents a multilevel cluster based protocol for energy efficient data communication. There is a cluster head selection phase followed by sensing of data, data gathering, aggregation and finally sending the aggregated data to the base station. Simulation results show that the performance of the proposed protocol is better than Energy Efficient Clustering Algorithm EECA for data aggregation in WSNs.
