Virtual wired transmission scheme using directional antennas to improve energy efficiency in wireless mobile ad-hoc networks

Energy efficiency improvement methods can be applied at different layers of the network architecture for mobile ad-hoc networks. There have been many research efforts on improving the performance parameters at physical, data link, and network layers. The properties of directional antennas have been exploited for better energy efficiency. Some of the properties include simultaneous multiple transmissions, lower interference levels, optimum channel access, and low overhead. This paper proposes a virtual wired transmission scheme with MAC and physical cross layer protocol using directional antennas to improve the performance characteristics of the system. Energy efficiency is the main focus of this paper and results obtained from MATLAB simulations have demonstrated the proposed scheme to be energy efficient.
