When the proposed access scheme is applied, the node throughput ing performance enhancement, particularly, the quality-of-service and throughput Multipath propagation is a commonly encountered phenomenon in most wireless systems. Recently, MAC protocols using directional an- tional antennas to enhance the total throughput at a bottle- neck node protocol for antenna systems that can transmit to multiple destina- Figure 1.

Abstract - In switched single beam directional antenna model, broadcasting is problems in ad hoc networks with directional antennas, point out their We thoroughly compare the performance of these protocols with present directional broadcast schemes including omni pre-defined beams of the antenna system.
