In this\ncontext, wireless sensor networks (WSNs) can play a very\nimportant role, since specialized sensors can be fruitfully\nexploited in order to generate\/receive signals by means of\nwhich the WSN can derive the position of nodes joined to\nthe objects to be tracked. The paper presents an original localization platform that exploits\na single\u2010hop WSN, based on a Microchip MCU and\na Cypress RF device, to track its moving nodes. Specifically,\nthe nodes of the network are divided into three sets:\nthe first set consists of anchor nodes that, according to the\ncommands from the sink (the central node of the WSN),\ngenerate ultrasonic pulses. These pulses are received by\nthe second set of (moving) nodes, which estimate the pulse time trip and communicate it to the sink. Finally, the last\nset is constituted by general purpose nodes that collect any\nkind of data from the surrounding field. The sink gathers\nall the data, computes the position of moving nodes, and transfers information to external users on the Internet. The algorithms adopted to manage the network and to localize\nmoving nodes are discussed. A working prototype\nbased upon the hardware platform, software, and protocol\ndescribed in this paper has been deployed and tested, and\nsome results are shown. Simulation results of the localization\nsystem are presented to show system scalability.<\/jats:p>","DOI":"10.1155\/2008\/569848","type":"journal-article","created":{"date-parts":[[2008,10,15]],"date-time":"2008-10-15T09:23:29Z","timestamp":1224062609000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Sensor Network\u2010Based Localization for Continuous Tracking                         Applications: Implementation and Performance Evaluation"],"prefix":"10.1155","volume":"2008","author":[{"given":"Livio","family":"Denegri","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandro","family":"Zappatore","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Franco","family":"Davoli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,10,14]]},"reference":[{"key":"e_1_2_7_1_2","doi-asserted-by":"crossref","unstructured":"IbrahimM.
