Energy Efficient Routing in MANET Using a Centralized Scheduler

A MANET is a self configuring network that involves numerous mobile nodes. MANETs use wireless connections to connect to different networks. The throughput and the network lifetime in Mobile Ad-hoc NETworks (MANETs) is improved using EC-MAC protocol with a centralized scheduler. This protocol enhances energy efficiency of MANETs and sustains the energy level of all the mobile nodes for a longer time. The intermediate nodes involved in data transmission can be selected based upon residual energy and location information. It provides a selection algorithm that chooses nodes with a suitable channel state, better location or position, an optimized energy drainage and better data transmission rate. The selection of a centralized scheduler not only preserves energy but also helps in a timely and orderly delivery of data without any collisions in the network.
