ABSTRACT
In an infrastructure wireless network, an ordinary network node is normally known as a Mobile Station (MS). The MS does not communicate directly with other MSs. Instead it communicates directly only with its Base Station (BS) and the BS forwards traffic appropriately. As a result, the BS and MS must be within radio communications range if the MS should have service. In contrast, nodes in a multihop wireless network communicate directly with their neighbors and route and forward traffic on their behalf. As long as the route exists between the source and destination, service can be maintained. A major advantage of multihop networks is that the region over which they provide coverage called the service area is larger than that seen for conventional infrastructure networks.
