As the WSN used in industrial and Environmental monitoring the most critical issues in the WSN is to reduce the energy consumption to extend the lifetime of the wireless sensor network. The intermediate hop nodes are working throughout the data transmission so those nodes drain out their energy which automatically reduces the life time of the wireless sensor network. To overcome thes e drawbacks the EAC-ASR protocol (Energy Aware Clustering Aggregate Node Rotation) with sink relocation method

... ur important processes which are present in this protocol was Clustering, data aggregation, mobile node rotation by swapping algorithm and sink relocation are applied. In this paper theoretical analysis and the simulation analysis are done and the result shows that the EAC-ASR protocol reduces the energy consumption and increase the energy efficiency.
