The research paper, presents a Wireless Sensor Network (WSN) for monitoring a patient’s physiological conditions continuously using Zigbee. In the experiment 3 groups of persons were made to undergo the test. Person A was in the age group of 1-10 years. Person B was in the age group of 11-30 years and person C was in the age group of 31-80 years. Physiological conditions of these 3 groups of pe...

We are witnessing the dawn of a new paradigm in Information and Communication Technologies (ICT), where large-scale embedded computing systems will interact with the physical environment in a ubiquitous and pervasive fashion. The landscape of potential new applications is tremendous; homeland security, environmental monitoring, health care, domotics, or factory automation are just a few elucida...

The development of health tele monitoring through wireless body area networks (WBANs) is an evolving direction in personalized medicine and home-based mobile health care. In a health tele monitoring system, a WBAN consists of a number of lightweight miniature sensors. The sensors measure physiological parameters such as electrocardiography (ECG), electroencephalogram (EEG), body temperature, an...

This paper details the overall design of a wireless home automation system (WHAS). This is fuelled by the need to provide supporting systems for the elderly and the disabled, especially those who live alone. The automation centre’s on recognition of voice commands and uses low-power RF ZigBee wireless communication modules which are relatively cheap. The home automation system is intended to co...

This paper is focusing on development of ZigBee transceiver at physical layer using IEEE 802.15.4. ZigBee technology was developed for a wireless personal area networks (PAN), aimed at control and military applications with low data rate and low power consumption. ZigBee is a low-cost, low-power, wireless mesh networking standard. First, the low cost allows the technology to be widely deployed ...

ZigBee is a recent wireless networking technology built on IEEE 802.15.4 standard and designed especially for low-data rate and low-duty cycle applications such as home and building automation and sensor networks. One of the primary goals of ZigBee is low power consumption and therefore long-living networks. Despite this goal, current network formation and routing protocols described in the Zig...

Real-time monitoring systems (RTMSs) have drawn considerable attentions in the last decade. Several commercial versions of RTMS for patient monitoring are available which are used by health care professionals. Though they are working satisfactorily on various communication protocols, their range, power consumption, data rate and cost are really bothered. In this study, the authors present an ef...

Zigbee is one of the most exciting wireless sensor network (WSN) technologies for monitoring and control. In our previous research, an integrated Zigbee RFID sensor network was designed as an ‘all-in-one’ system as well as a connectionless inventory tracking solution for Humanitarian Logistics Center (HLC) resource management. Various field trials, which have justified the feasibility and featu...
