Algorithm for Optimizing First Node Die (FND) Time in LEACH Protocol

Abstract

Optimizing lifetime and efficiency is the most critical requirement in WSN. Due to remote deployable nature frequent
access is not possible for nodes in WSN. Data Collection, processing and transmission are key function of WSN node.
The whole functionality of the node depends upon the battery lifetime and replacement of the battery is not possible. User
can’t access these nodes once they are deployed. So there is a requirement of energy efficient protocol in order to
improve the lifetime of the network. The most common protocol used to enhance the lifetime of the network is clustering
based protocol still there is a need for optimizing the communication protocol in which different nodes communicates
with the Cluster Head and Base Station. In this paper an improved LEACH Protocol for heterogeneous network is
proposed. In the proposed method algorithm is optimized for increasing first node die (FND) time. The protocol also
focuses on lifetime enhancement and maintaining Quality of the Service (QoS) of the network.
