Download or read book The Reliability of Signal Strength for Localization of High density ZigBee Wireless Networks written by and published by . This book was released on 2007 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates the reliability of ZigBee signal strength within a high-density wireless network, specifically looking at the Link Quality Indicator (LQI) as provided by the physical layer and accessible at the networking and application layers within the stack protocol. It also investigates methods by which LQI can be used for discovery, identification, and localization of nodes within a ZigBee wireless network. The thesis concentrates on practical approaches specifically as it would pertain to commissioning a high-density network for an application such as lighting control in building automation. There are seven potential algorithms proposed using factors such as minimum distance error, perceived confidence, and triangulation. Experiments, which explore the reliability of signal strength indicators, reveal that the fluctuations of the signal strength indicate that a simple, inexpensive algorithm is insufficient. Simulations, which explore varying conditions such as network layouts, node-count, and node-density, reinforce this notion; however, this thesis also shows that more complicated and expensive methods do show promising results. Using the simplest of methodologies, the experiments and simulations result in 30-35% accuracy. However, with the more complicated methodologies (using techniques such as reiteration, emulation, and cooperation), the results reveal accuracies of 80-90%. This thesis concludes from these results that a simple algorithm and methodology may not be sufficient but that there are approaches that can improve the results. However, the cost of these approaches may be deemed too high for practical use. Further exploration in these methodologies, though, should show promise that more sufficient accuracies without sacrificing too much cost are attainable.

Download or read book Wireless Communication in Underground Mines written by L. K. Bandyopadhyay and published by Springer Science & Business Media. This book was released on 2009-08-29 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wireless communication has emerged as an independent discipline in the past decades. Everything from cellular voice telephony to wireless data transmission using wireless sensor networks has profoundly impacted the safety, production, and productivity of industries and our lifestyle as well. After a decade of exponential growth, the wireless industry is one of the largest industries in the world. Therefore, it would be an injustice if the wireless communication is not explored for mining industry. Underground mines, which are characterized by their tough working conditions and hazardous environments, require fool-proof mine-wide communication systems for smooth functioning of mine workings and ensuring better safety. Proper and re- able communication systems not only save the machine breakdown time but also help in immediate passing of messages from the vicinity of underground working area to the surface for day-to-day normal mining operations as well as for speedy rescue operations in case of disaster. Therefore, a reliable and effective commu- cation system is an essential requisite for safe working, and maintaining requisite production and productivity of underground mines. Most of the existing systems generally available in underground mines are based on line (wired) communication principle, hence these are unable to withstand in the disaster conditions and dif?cult to deploy in inaccessible places. Therefore, wireless communication is an indispe- able, reliable, and convenient system and essential in case of day-to-day normal duty or disaster situations.
