Design and management of wireless mesh networks

Wireless mesh networks (WMNs) consist of stationary wireless routers interconnected by wireless links with a small fraction acting as gateways to the Internet via wired (e.g., Ethernet) or wireless (e.g., WIMAX) links. One of the key challenges facing WMNs is supporting high throughput. The maximum available bandwidth degrades rapidly with increasing distance between the source and destination in the mesh network (i.e., the number of wireless routers traversed between the mobile device and the gateway to the Internet); this degradation is caused due to interference from neighboring hops and paths. For example, in a network with identical and omnidirectional radio ranges, going from a single hop to two hops halves the throughput of a flow. This can be disastrous for network providers eying to provide the level of latency/throughput people are accustomed to with their wired networks.
