A Mechanism to Enhance Lifetime of NEW LEACH Protocol in WSN

Due to the extensive range of applications the use of wireless sensor networks (WSNs) in past few years have increased a lot and it has become a hot research area now a days. One of the important issues in wireless sensor network is the intrinsic limited battery power in network sensor nodes. Since most of the energy is consumed by the transmission and reception, energy efficient routing protocol is required to enhance the lifetime of WSN. In this paper we presents the review of existing hierarchical routing protocol NEW LEACH and proposed a new approach that is better and more energy efficient than the existed approaches. In the proposed work, two enhancements are made. These enhancements are efficient cluster head replacement technique by using dynamic threshold value and the concept of upper threshold for sending data. Both NEW LEACH and Proposed protocol are simulated in MATLAB. The result shows that our proposed algorithm performs better than the NEW LEACH in terms of network lifetime.
