Optimization of Positioning Capabilities in Wireless Sensor Networks: from power efficiency to medium access (2016)
Abstract / truncated to 115 words
In Wireless Sensor Networks (WSN), the ability of sensor nodes to know its position is an enabler for a wide variety of applications for monitoring, control, and automation. Often, sensor data is meaningful only if its position can be determined. Many WSN are deployed indoors or in areas where Global Navigation Satellite System (GNSS) signal coverage is not available, and thus GNSS positioning cannot be guaranteed. In these scenarios, WSN may be relied upon to achieve a satisfactory degree of positioning accuracy. Typically, batteries power sensor nodes in WSN. These batteries are costly to replace. Therefore, power consumption is an important aspect, being performance and lifetime ofWSN strongly relying on the ability to reduce it. ... toggle 8 keywordswireless sensor networks – positioning – tracking – power efficiency – game theory – distributed signal processing – topology – cluster-tree
