Abstract :
Ultra-wideband (UWB) technology has proven to be useful in short range, high data rate, robust, and low power communications. These features can make UWB systems ideal candidates for reliable data communications between nodes of a wireless sensor network (WSN). However, the low powered UWB pulses can be significantly degraded by channel noise, inter-node interference, and intentional jamming. In This work we present a novel interference suppression technique for UWB based WSN that promises self-organization in terms of power conservation, scalability, and channel estimation for the entire distributed network.
