Design and analysis of medium access control and network Protocols for ultra-wideband ad-hoc Networks


Ultra-Wideband (UWB) is an emerging radio technology that has the potential to become the new enabler for the next generation of wireless networks.

The strength of the UWB radio technique lies in its use of extremely wide transmission bandwidths which results in desirable capabilities including accurate location and position ranging, lack of significant fading, high multiple access capability, and possible material penetration.

The technology has several distinct characteristics that set it apart from other tethered or untethered technologies. Thus, extremely challenging theoretical and practical problems are raised, regarding the network performance and management.

Our main goal is to understand the fundamental performance limits of UWB networks and to utilize the unique UWB properties in order to design algorithms that enable us to approach these performance limits. We intend to investigate problems related to the design and management of UWB networks, regarding mainly the Medium Access Control (MAC) and the network layers.

In particular, we wish to study the issues of power-aware topology construction and MAC design and management. The proposed research includes a theoretical study (analytical modeling and development of optimal and approximation algorithms) and a practical study (simulation and evaluation in testbeds). We believe that the results will provide important input to the EU standardization efforts.

The outgoing phase will be performed in the Laboratory for Information and Decision Systems in MIT, while the re-integration phase will be conducted in the Dept. of Electrical Engineering in the Technion. The project is expected to initiate long-term collaboration between the Technion and MIT in the area of wireless networking.
