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.

Keywords: WSN, Cluster Head, Heterogeneous, Lifetime, FND, QoS
