Abstract: Wireless sensor networks have been widely used in health care monitoring systems. With improved technologies in health care monitoring, the demand for high data rate transmission has also increased. Ultra wideband (UWB) is a short range wireless physical layer technology which is used to achieve high data rates in wireless sensor networks, without compromising the power consumption limits. The hardware implementation of UWB receivers is complex and also it consumes high power. This drawback can be overcome either by using a transmitter only method or by using a less complex narrow band wireless technology for receiver. The later method is proposed here with a narrow band feedback system, which increases the throughput. Second part of the paper deals with reducing the routing overhead of the network with a probability based method exploiting the neighbor coverage area. Simulation results show that the proposed methods improve bit error rate and throughput.
