In this paper, a particle swarm optimization (PSO) based multilateration algorithm is presented for a UWB communications based sensor network. The particle swarm uses simple operators and is a bottom-up approach for identifying the location in a 2D space. Hence the PSO uses less energy. For comparison we present two alternative approaches traditionally used for this problem. The first one is (a) traditional...
Localization algorithms are required for indoor wireless sensor network (WSN) applications because the identification of real positions can upgrade the importance of sensing information. In this paper, we introduce a efficient algorithm which can improve the accuracy of location identification by employing jumper setting at each sensor. The proposed algorithm perform localization more accurately than...
