Raghavaraju Journal On Wireless Communication Networks 2320-2351 6 1 7 11 10.26634/jwcn.6.1.13770 Wireless Sensor, Lifetime, Clusters, K-Means, Power Around 70% of the aggregate vitality is scattered for information transmission in the greater part of the Wireless Sensor Network (WSN) applications. Another basic issue is security in wireless networks and various security plans are created to give administrations of security. In any case, these calculations have their own shortcomings, for example, helpless against picked plaintext assault, and computational multifaceted nature Routing of energy efficiency and Communication of data security in WSN. This paper proposes Improved LEACH/ILEACH protocol which increases network lifetime and it will improve the quality of QoS. Along the network lifetime, they propose a secure way to aggregate the data in ILEACH. The experimental results show that the proposed technique is giving better results in terms of energy consumption than existing techniques. April - June 2017 Copyright © 2017 i-manager publications.
