A new wake-up receiver is proposed to reduce energy consumption and latency through adoption of two different data rates for the transmission of wake-up packets. To reduce the energy consumption, the start frame bits (SFBs) of a wake-up packet are transmitted at a low data rate of 1 kbps, and a bit-level duty cycle is employed for detection of SFBs. To reduce both energy consumption and latency, duty...
A high-energy-efficiency wireless communication link scheme is proposed for portable medical applications with strict resource constraints. The scheme is especially optimized for the application systems with the star-topology master-slave network, i.e., the network formed by a portable data-logger (master) and several sensor nodes (slaves). The proposed scheme eliminates “non-effective” operation...
This paper presents a distributed fermat-point range estimation strategy, which is important in the moving sensor localization applications. The fermat-point is defined as a point which minimizes the sum of distances from three sensors inside a triangle. This point is indeed at the trianglepsilas center of gravity. We solve the problems of large errors and poor performance in the bounding box algorithm...
