The unmanned aerial vehicle (UAV) and the ground (UGV) can complete complex tasks through information sharing ensure mission execution capability of multiple carrier platforms. At same time, cooperative navigation use interaction between multi-platform sensors to improve relative positioning accuracy entire system. Aiming at problem deviation system model due gross errors in sensor measurement ...

in wireless sensor networks (wsns), localization algorithms could be range-based or range-free. the approximate point in triangle (apit) is a range-free approach. we propose modification of the apit algorithm and refer as modified-apit. we select suitable triangles with appropriate distance between anchors to reduce pit test errors (edge effect and non-uniform placement of neighbours) in apit a...

background: bilateral neck exploration is the gold standard for parathyroid adenoma localization in primary hyperparathyroidism. but surgeons do not have adequate experience for accurate surgical exploration and new methods are developed for surgery like unilateral exploration and minimally invasive surgery, thus, preoperative localization could reduces time and stress in surgical performance. ...

Wireless sensor networks attracting a great deal of research interest. Accurate localization of sensor nodes is a strong requirement in a wide area of applications. In recent years, several techniques have been proposed for localization in wireless sensor networks. In this paper we present a localization scheme with using only one mobile anchor station and received signal strength indicator tec...

We propose a decentralized method to perform mutual localization in multi-robot systems using anonymous relative measurements, i.e., measurements that do not include the identity of the measured robot. This is a challenging and practically relevant operating scenario that has received little attention in the literature. Our mutual localization algorithm includes two main components: a probabili...

Increasingly ubiquitous wireless technologies require novel localization techniques to pinpoint the position of an uncooperative node, whether the target be a malicious device engaging in a security exploit or a low-battery handset in the middle of a critical emergency. Such scenarios necessitate that a radio signal source be localized by other network nodes efficiently, using minimal informati...
