A Sector Based Energy Efficient Adaptive Routing Protocol for Large Scale MANET

A MANET is a type of ad-hoc network that can change locations and configure itself on the fly. A MANET involves mobile platforms which are free to move arbitrarily and there may be frequent link breakage due to battery. We propose a novel adhoc routing protocol named as Sector based Energy Efficient (SEA) routing protocol with high data throughput. To overcome the link breakage in MANET, the proposed protocol also uses the mathematical geometrical progression method, which minimizes the redundancy distance calculation and routing overhead. We also combine the mathematical model with weight based route estimation techniques. It selects the longest life span to estimate the route stability derived from received signal strength. The simulation results shows that the proposed SEA protocol yields better performance then the existing protocols namely EDRP, EDNR, DOA and AODV in terms of packet delivery ratio and energy consumption.
