SAUR: A Service Aided UWB Routing for Wireless Mesh Networks

In this paper, a routing algorithm for Wireless Mesh Networks (WMNs) over Ultra Wide Band (UWB) is proposed for High Definition (HD) video transmission. In order to support multiple services smoothly over UWB, a new routing algorithm called Service Aided UWB Routing is developed. Unlike conventional routing algorithms, the proposed method is driven by application services' requirements, which determines the relays and the corresponding resources allocation for various types of application packets, thus reducing possible interferences between different streams. The proposed routing approach significantly outperforms the traditional routing algorithms, since it is capable of adjusting routing policies dynamically according to application services in fast changing topologies, which makes it especially suitable for the Video on Demand (VoD) application over UWB.
