Effect of Mobility on Performance of MACAW Mechanism of IEEE 802.11 Adhoc Networks

摘要

Packet Collisions in wireless communication are one of the most causes of network performancedegradation. MACAW mechanism is a popular and widely used mechanism to reduce packetcollisions that arise due to the hidden terminal problem in mobile ad-hoc networks. However;Mobility is considered a vital issue in mobile ad-hoc networks that has not been thoroughlyinvestigated. A real time simulation is carried out to measure the Throughput and the PacketDelivery Ratio of an ad-hoc network under Shadowing propagation model using MACAWmechanism with different mobility scenarios.
