Abstract of Dissertation presented to COPPE/UFRJ as a partial fulfillment of the requirements for the degree of Master of Science (M.Sc.) WIRELESS SENSOR NETWORKS IN MONITORING AND CONTROL Sergio Torres dos Santos June/2007 Advisors: Department: Aloysio de Castro Pinto Pedroza Luís Henrique Maciel Kosmalski Costa Electrical Engineering The advances in wireless technologies and microelectronic have enabled interesting new applications for wireless devices. With this development it appeared an increasing demand for remote monitoring and control in industrial and residential environments. Some technologies are already met in the market, destined to this type of application and amongst them the ZigBee standard is distinguished. These applications suffer restrictions in its performance due to internal interference between nodes. This work shows this influence, through the throughput in different rates and amounts of nodes, showing conditions that must be respected and be prevented in a scenery of automation and control, where if demand more reliability than a data high rate. This study it can not only serve of base for other works with ZigBee sensors networks, but mainly for designers in the creation of ZigBee networks, considering aspects as: scenery, number of nodes, throughput and packet delivery ratio. vi
