This article established a double antennas positioning method and system model. Considering the impact of white Gaussian noise, SNR difference and time difference of arrival of dual-antenna can be calculated at the receiving end to make equations in multi-path fading channel. In the space of two-dimensional the wave source location can be expressed as the function of SNR difference and time difference.
In this paper, we proposed a novel multi-agent-based interoperable wireless sensor network (WSN) model. It provided generalized frameworks to address some critical issues existed in the WSN such as interoperability, time synchronization, power management and distributed computation. To address these issues, we developed a model that was based IEEE 1451 and IEEE 1588 standards to address sensor interoperability...
In this paper, we describe a reliability model which can be used to analyze the performance and power consumption in resource constrained, data rate scarce, mobile agent-based wireless sensor network (WSN) systems. The primary model is referred to as a generalize access structure congestion (GGC) system which is an extended model from a circular sequential k-out-of-n congestion (CSknC). There are...
In view of the shortcomings exist in current process of medical transfusion, a wireless distributed system for transfusion supervision was designed with infrared detection technology, computer network technology, embedded system technology and wireless transmission technology. The system is a network which consisted of a host computer, transfusion monitors, and interconnection mechanisms between the...
