The introduction of wireless solutions in the assisted living area brings convincing advantages in terms of staff burden reduction, observation reliability and treating measures response time. The paper identifies some typical application requirements. Applicability analysis of existing solutions is made. Z...

This paper presents a Maximum Likelihood Location Estimation (MLLE) algorithm for the home network environments. We propose a deployment of cluster-tree topology in the ZigBee networks and derive the MLE under the log-normal models for the Received Signal Strength (RSS) measurements. Experiments are also conducted to validate the effectiveness of the proposed algorithm. key words: ZigBee, locat...

In view of the traditional faults of wire network that complex wiring and costly wired network, a set of Zigbee wireless network technology based on the temperature and humidity data acquisition and control system is designed in this paper to improve the environmental temperature control in piggery. The Zigbee system which can monitor the real-time information of temperature and humidity in pig...

Severe natural conditions and complex terrain make it difficult to apply precise localization in underground mines. In this paper, an anchor-free localization method for mobile targets is proposed based on non-metric multi-dimensional scaling (Multi-dimensional Scaling: MDS) and rank sequence. Firstly, a coal mine wireless sensor network is constructed in underground mines based on the ZigBee t...

Public Addressing System (PA) is an electronic sound and amplification distribution system with a microphone, amplifier and loudspeakers. PA systems are widely used to make announcements in public, institutional and commercial buildings and locations . In PA systems cost, quality and expansion are the major factors that affect the working and implementation of the system. The Zigbee based monit...

In this paper, we analyze the performance of clustered Zigbee wireless sensor networks (WSNs) with data fusion. Performance indicators at both physical (probability of decision error) and network (network transmission rate, throughput, aggregate throughput, delay, and network lifetime) layers are considered. Data fusion is carried out at the access point (AP) and, in clustered configurations, a...

for making life more comfortable, safer and more intelligent, a system for remote monitoring of smart home is proposed based on ARM and ZigBee. This system not only can centralize and monitor family affairs by gathering computer technology, embedded technology, sensor technology, and network communication technology, but also can meet the pursuit of high quality life in the information age by c...

Wireless sensor network (WSN) has attracted more and more attentions in the computer science and communication research community. It has appeared a great potential in numerous industrial applications. In this paper a wireless sensor network based on ZigBee protocol for the measurement system in grain storage was developed and tested as an alternative to the cable system, which showed better ef...

Resumen. Este trabajo trata sobre un sistema de monitoreo remoto a través de una pantalla inteligente para sensores de temperatura y corriente utilizando una red híbrida CAN−ZIGBEE. El CAN bus es usado como medio de transmisión de datos a corta distancia mientras que Zigbee es empleado para que cada nodo de la red pueda interactuar de manera inalámbrica con el nodo principal. De esta manera la ...
