Executive Summary

Computer networks have long suffered from congestion. Congestion occurs when an increase in the offered load results in a decrease in the effective throughput of the network. The basic cause is that the short term packet arrival rate at some gateway exceeds its service rate. Existing congestion control schemes treat congestion as an individual problem and propose ad hoc solution that are dissatisfied. Wireless multi-hop networks have many potential applications, e.g., a small stand-alone network for group of mobile users (Mobile Ad Hoc Networks), a cost efficient stubnetwork to connect to the Internet (Wireless Mesh Networks), or a self-organized community network connecting houses together (Wireless Community Networks).
