An indoor navigation system based on passive RFID is described. It allows the user to move autonomously resorting to a grid of RFID tags for localization and simple procedures to determine the position and to plan the route. Ad-hoc designed RFID tags permit to achieve reliable and accurate position estimation while a proximity algorithm allows real-time localization. Many details of the localization...
The positions of the sensor nodes in wireless sensor networks for precision agriculture must be required first. Position estimation generally includes errors due to the measurements of distance. Erroneous positions are propagated from a node to other nodes exacerbating the degree of errors in the estimation of the positions of these nodes. In this study, we evaluated the performance of NMDS-RSSI localization...
Vehicle-to-vehicle communications via dedicated-short-range-communication (DSRC) devices will enable safety applications such as cooperative collision warning. These devices use the IEEE 802.11p standard to support low-latency vehicle-to-vehicle and vehicle-to-infrastructure communications. However, a major challenge for the cooperative collision warning is to accurately determine the location of...
