MAC Protocols 802.11: A Comparative Study of Throughput Analysis and Improved LEACH

A throughput is a measure of successful data transmission through a terminal in a given time. There is a significant number of surveys that have been published to measure the performance of MAC protocols and each MAC channel. There is a substantial need to perform a comparative analysis of achieved results that can provide a comprehensible result for the end-users. In our work, we have applied different methods to obtain the throughput of contention-free and contention-based protocols. We have provided a brief comparison between different protocols of the same class to accentuate the efficient protocols. Our paper incorporates collision avoidance MAC channels, as the collision avoidance techniques provide better usability of protocols than the collision detection techniques. We have also proposed an efficient way to increase the life span of the Low-energy Adaptive Clustering Hierarchy (LEACH) protocol using Time Division Multiple Access (TDMA). The goal to obtain the maximum effectiveness of a network can be achieved by maximal utilization of the throughput. In this paper, we have provided a brief comparison of different MAC protocols by using the throughput parameter, and we have also proposed a new method to increase the efficiency of LEACH protocol.
