ABSTRACT
Wireless Ad Hoc Networks comprise a fast developing research area with a vast spectrum ofapplications. Wireless sensor network systems enable the reliable monitoring of a variety of environmentsfor both civil and military applications. The Energy efficiency continues to be a key factor in limiting thedeployability of ad-hoc networks. Deploying an energy efficient system exploiting the maximum lifetimeof the network has remained a great challenge since years. The time period from the instant at which thenetwork starts functioning to the time instant at which the first network node runs out of energy, i.e. thenetwork lifetime is largely dependent on the system energy efficiency. In this paper, we look at energyefficient protocols, which can have significant impact on the lifetime of these networks. The cluster headsget drain out maximum energy in the wireless ad hoc networks. We propose an algorithm that deals withminimizing the rate of dissipation of energy of cluster heads. The algorithm LEAD deals with energyefficient round scheduling of cluster head allocation of nodes and then followed by allocation of nodes tothe cluster heads maximizing network lifetime using ANDA [1, 2]. We compare our results with theprevious works.
