Abstract

Ultra Wideband (UWB) technology provides high-speed, low-power wireless networks with a low probability of detection and interception, and is resistant to jamming. This promising technology lacks support above the physical layer to provide capabilities that the Army requires for intra-vehicle communication for real-time, multimedia data streams. ATC-NY proposes to create the SQUAWB (Secure QoS-enhanced UltrA WideBand) protocol to support the efficient use of the frequency spectrum among multiple simultaneous users. SQUAWB will support QoS guarantees and provide security in a dynamic environment in which the underlying capabilities of the physical layer, such as bandwidth, change due to the environment and adversaries. SQUAWB will be developed as a MAC-layer protocol to interface with the physical layer and a middleware layer protocol to interface with the application layer. The middleware layer will use adaptive, reflective techniques to let it adapt to the changes at the lower levels. In addition, the middleware layer handles the security and QoS details that most application programs currently do not handle. In Phase I, we will create the MAC and middleware layer protocols and perform simulations to demonstrate the feasibility and benefits of SQUAWB.
