Packet Collisions in wireless communication are one of the most causes of network performance degradation. MACAW mechanism is a popular and widely used mechanism to reduce packet collisions 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 thoroughly investigated. A real time simulation is carried out to measure the Throughput and the Packet Delivery Ratio of an ad-hoc network under Shadowing propagation model using MACAW mechanism with different mobility scenarios.
