Energy efficiency technique plays an important role in saving the energy. To improve network lifetime, an efficient data aggregation protocols which help to eliminate redundant data transmission in a wireless sensor network must be in place. In this paper, concentric clustering where each node sends data to the CH. The CH aggregates and sends it to the BS via coordinate nodes. Cluster Head (CH) is selected using K nearest neighbor algorithm and Distributed RANDomized (DRAND) time slot for data transmission. This approach consumes a minimum amount of energy. The drawbacks of existing protocols are listed and compared with the proposed protocol.
