Mobile ad hoc network (MANET) is a decentralized, infrastructure less network, where the mobile nodes can transmit the information energetically. Optimizing the energy consumed during transmission is one among the essential requirements in MANET because of the restricted battery power and intricacy in replacing the battery. Transmission Range based Optimal Backbone Path (TROBP) algorithm is proposed to resolve this issue. TROBP algorithm constructs an optimal backbone path based on multi-criterion approach to minimize power consumption during transmission mode. Multi-Criterion approach is designed based on the periodic estimation of criteria’s that includes transmission range and residual energy of optimal node, link stability of optimal backbone path and also the load distribution during transmission. TROBP algorithm implements a scheduling scheme for optimizing energy consumption in a high mobility environment. © 2020, Engg Journals Publications. All rights reserved.
