Supervisory Medium Access Control for Multi-Hop Ad Hoc Networks

IEEE 802.11 MAC is the most commonly used MAC layer protocol in multi-hop ad hoc networks. When the network load becomes heavy, the throughput performance of IEEE 802.11 MAC is decreased because of the high channel collision. In this letter, we analyze the throughput of multi-hop ad hoc networks and propose an offered load control scheme to maximize the throughput based on a supervisory control framework
