“…In order to achieve accurate positioning with WSN, a large number of localization algorithms are established, such as (Blumrosen, Hod, Anker, Dolev, & Rubinsky, 2010;Wang, Jia, Lee & Li, 2003;Seidel & Rapport, 1992;Smailagic & Kogan, 2002;Bahl & Padmanabban, 2000;Seidel & Rappaport, 1991;Hightower, Want & Boriello, 2000). The distance between sensor nodes can be simply estimated according signal strength consumption.…”
