Wireless sensor network is a network which engross large number of sensor nodes for data transmission. Data Transmission is transfer of relevant data from point-to-multipoint wireless communication channel. However efficiency of data transmission and energy consumption while data transferring depends largely influenced by the kind of protocol being used. Lower Energy Adaptive Clustering Hierarchy Leach and improved leach are kind of different protocols from the same class which can pomp different results and variations when used under same number of rounds. This paper appraises the comparative analysis of both the protocol in tabular and graphical form by using MATLAB software and Ant Colony Optimization (ACO) algorithm.
