Abstract :
In this correspondence, we show that the uniform throughput capacity of an ultra-wideband (UWB) power-constrained ad hoc network is given by , where is the per-node power constraint, is the fading exponent of radio signal and is the number of nodes randomly distributed inside a disk of unit area. This is a stronger result than the upper bound and the lower bound previously shown by Negi and Rajeswaran. Our proof is simple given the prior work by Gupta and Kumar.
