OTP: OPTIMAL DATA TRANSMISSION PATH ALGORITHM TO DISCOVER ENERGY EFFICIENT ROUTES IN MOBILE AD-HOC NETWORKS

Abstract

Mobile Ad-hoc Network (MANET) is a kind of wireless network that consists of self-configuring mobile nodes which can communicate using wireless links As mobile nodes can freely move in and out of a MANET, its topology structure can also change over time, i.e. can’t have fixed topological structure as wired networks. This causes many problems like link failure, redundant links, etc. Introducing relay nodes to avoid link failure can’t be an ideal solution. Therefore, a novel algorithm to select Optimal Transmission Path (OTP) algorithm in a MANET has been proposed. The proposed OTP algorithm discovers an energy efficient route from source mobile node to the destination mobile node and also minimizes hop count and delay. This method mainly relies on the transmission- and receiving power of each node for efficient node selection in the current network. This protocol reduces the average transmission redundancy and enhances the packet delivery ratio. Simulations results points out that the proposed OTP algorithm attains better delivery ratio and also improve the energy of the network.
