NAT-ZigBee: NAT-Based Address Assignment for Scalable ZigBee Networks
ZigBee has been considered as one of the promising communication protocols for low-rate wireless personal area networks. Among the well-known ZigBee topologies, ZigBee cluster-tree is especially suitable for wireless sensor applications with its supporting of power-saving operation and light-weight routing. Due to the restriction of configuration parameters, some devices could be prohibited to ...
متن کاملIntelligent Helmet for Coal Miners with Voice over ZigBee Andenvironmental Monitoring
A cost effective ZigBee based wireless mine supervising system with voice over ZigBee (VoZ) is presented here. Here we design a smart helmet, which enable the helmet as a mobile sensor node of ZigBee wireless sensor networks, gathering parameters the temperature, humidity and illumination level of underground environment and will alert the central management unit in case of abnormal condition. ...
متن کاملAn ECA-Based ZigBee Receiver
Element CXI's Elemental Computing Array (ECA) delivers faster reconfiguration time and higher computational density than Field Programmable Gate Arrays (FPGAs) with similar computational power. It provides higher computational power than Digital Signal Processors (DSPs) with similar power consumption and price. It also utilizes a library-based graphical development environment promoting ease of...
متن کاملZIGBEE based Public Addressing Systems
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...
متن کاملZigBee-based remote patient monitoring.
This paper describes a developed continuous patient monitoring system based on the ZigBee protocol. The system was tested in the hospital environment using six sensor devices in two different modes. For electrocardiogram transmission and in the absence of hidden-nodes, the system achieved a mean delivery ratio of 100% and 98.56%, respectively for star and 2-hop tree network topologies. When sen...
