A power-efficient routing metric for UWB wireless mobile networks

In this paper an UWB-specific, power-efficient routing strategy is described. The proposed method is based on the ranging capabilities offered by UWB. It is shown that emitted power levels as well as multi-user interference are significantly reduced. The new routing metric is analyzed against a traditional metric based on the number of hops for various transmission ranges, i.e. network connectivity conditions, and various traffic conditions. A strategy capable of adapting to variable network connectivity conditions is finally proposed.
