Evaluation & analysis of energy efficient extension to LEACH protocol for WSN

In this paper extension to LEACH protocol i.e. Modified LEACH protocol has been analytically and critically analyzed. It has been shown that the hard threshold value in Modified LEACH protocol has a direct impact on the network lifespan of a wireless sensor network. More the initial energy more will be the net lifetime of the network, as the number of alive nodes will be more. Simulation and analytical results reveal that the Modified LEACH protocol outperforms the traditional LEACH in every aspect.
