Localization problems of the WSNs (wireless sensor networks)geostationary nodes are studied,and the localization algorithm (Fast and Rough Nodes Location Algorithm) based on the communication power mediation for geostationary nodes by receiving the localization information from anchor nodes is presented.The localization estimate of localized nodes is executed in lesser field for higher accuracy.The...
Aiming at the positioning problem of Ad-Hoc networks of sensors node location, a beacon selected localization algorithm (BSLA) is proposed in this paper. The proposed method considers sufficiently both the topology relationship among beacons and the topology relationship between beacon nodes and unknown nodes. We introduce the concept of collinearity and apply it into the localization of the multihop...
In this paper, we propose an efficient range-free localization algorithm based on shortest path information. The proposed method is a kind of range-free localization algorithm which only uses the proximity information between sensor nodes. In the proposed method, an efficient distance vector based on shortest path information is proposed. The proposed method is applied to various kinds of network...
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...
