The development of telemonitoring via wireless body area networks (WBANs) is an evolving direction in personalized medicine and home-based mobile health. A WBAN consists of small, intelligent medical sensors which collect physiological parameters such as electrocardiogram, electroencephalography, and blood pressure. The recorded physiological signals are sent to a coordinator via wireless technologies,...
Nowadays, with increase in ageing population, Health care market keeps growing. There is a need for monitoring of Health issues. Body Area Network consists of wireless sensors attached on or inside human body for monitoring vital Health related problems e.g, Electro Cardiogram (ECG), ElectroEncephalogram (EEG), ElectronyStagmography(ENG) etc. Data is recorded by sensors and is sent towards Health...
With the increasing economic development, the number of cars in the city has been increasing continuously. Though some RFID parking lot management systems have been set up, most rely on manual management and efficiency is very low. The major cause is that a well information communication system is not built between the parking lot manager and the parking spaces. In order to solve the problem, a scheme...
ZigBee wireless technology is a global standard of short-range and low-data-rate for wireless sensor networks. To reduce the redundant overhead and to conserve nodes' energy in energy-constrained and multi-PAN ZigBee networks, we propose in this paper a cross-layer energy-balanced inter-PAN routing algorithm (CEIPR). The proposed algorithm has three key functionalities: (1) establishes the multipath...
IEEE 802.15.4/ZigBee sensor networks support small power consumption and node expansion compared to other network standards for WSN. Body sensor networks (BSN) require a number of sensors for sensing medical information from human body, and low power consumption to monitor a patient's status for a long time. However, ZigBee has limited bandwidth and is thus hard to support real time data transmission...
Recently, the necessity for power saving in Wireless Sensor Networks (WSNs) is crucial particularly in mission essential fields like military and medical applications. A communication network consists of nodes, every of that has computing power and may transmit and receive messages over communication links, in wireless. During this paper think about zigbee network formation and provides network protection...
Recent advancements in wireless communications technologies bring us one step closer to provide reliable Telecare services as an alternative to patients staying in a hospital mainly for monitoring purposes. In this research we investigate the efficiency of IEEE 802.15.4 in a simple scenario where a patient is being monitored using an ECG and a blood analysis module. This approach binds well with assisted...
Wireless sensor networks (WSNs) are promising tools to change the way the power grid is monitored and controlled. This paper presents the design, simulation and evaluation of ZigBee WSNs that are used for condition monitoring of delay sensitive data in wind turbines. It also presents an approach to reduce the end-to-end delay and provide service differentiation for sensor nodes that are transmitting...
The recent emergence of the sensor networks technology is significantly impacting the capabilities for automated distributed monitoring of environments. The low manufacturing cost of sensors, increased coverage and accuracy in distributed sensing due to their large deployments and their ability to operate in inhospitable terrains has made them an amenable technology for various surveillance and monitoring...
Our earlier embedded QoS-aware residential gateway (EmQRG) for real-time class-based queuing (CBQ) bandwidth management is reviewed and experimentally demonstrated. EmQRG's high QoS is demonstrated in conjunction with a wireless ZigBee network of temperature/humidity monitoring sensors. Critically, the EmQRG sends a top-priority over-temperature alarm when any temperature/humidity module reports a...
In order to realize the Smart Grid vision, it is necessary to have guaranteed Quality of Service (QoS) for the communication and networking technology used in various stages of the Smart Grid, ranging from power generation, transmission, distribution, to the customer applications. The low cost wireless protocols such as Zigbee (using IEEE 802.15.4 defined physical and MAC layer) and Bluetooth (IEEE802...
A Emergency Communication System based on Wireless Mesh Network (ECS-WMN) is proposed, which is easy to deploy and report the incidents and information such as personnel positions to the field rescue center and related members of rescue groups using different approaches, such as pop-ups on a computer or PDA screen, WiFi video terminals, WiFi cell phones and so on. A ECS-WMN consists of a WMN gateway,...
