Difference between Wireless Mesh Network and Mobile Ad hoc Network

Wireless mesh networks (WMNs) have been proposed as an effective solution for ubiquitous last-mile broadband access. WMNs are characterized by static mesh routers connected by wireless links to each other, each providing connectivity to end hosts. The cost and deployability of WMNs make them particularly attractive for providing last-mile broadband access in rural and suburban areas. The main difference between WMNs and other multi-hop wireless networks such as mobile ad-hoc networks and sensor networks are that the routers in WMNs are static and typically not power-constrained. This shifts the focus of routing from dealing with mobility to finding high throughput routes. MAP currently consists of 32 nodes and is capable running in both 802.11a or 802.11b/g mode. MAP has been recently enhanced with multi-radio support for higher capacity.
