The effect of impulsiveness in inter-cell interference on throughput of TH-IR-UWB networks

Abstract

This paper considers a wireless sensor network with Time-Hopping-Impulse- Radio Ultra Wide Band as the physical layer. The network is structured as a group of interconnected cells that are not synchronized with each other. In such an unsynchronized environment, inter-cell interference is not Gaussian, but generalized Gaussian. For such a non-Gaussian random interference, its impulsiveness is determined by the Kurtosis of the distribution. This paper shows that the Kurtosis can be controlled by adjusting some practical parameters, such as pulse shape, pulse length, slot duration, number of slots per frame, number of users, etc. Further, this paper shows that network throughput can be maximized by controlling the impulsiveness. The finding has been validated through simulations. ©2010 IEEE.
