On Sensor Network Localization Using SDP Relaxation
Sensor network localization attempts to determine the locations of a group of sensors given the distances between some of them. The Semidefinite Programming (SDP) relaxation of this problem is widely used to determine the locations of the sensors [1]. In this paper, we analyze and determine a number of conditions that guarantee that the SDP relaxation is exact, i.e. gives the correct solution. ...
متن کاملExploiting Sparsity in SDP Relaxation for Sensor Network Localization
A sensor network localization problem can be formulated as a quadratic optimization problem (QOP). For quadratic optimization problems, semidefinite programming (SDP) relaxation by Lasserre with relaxation order 1 for general polynomial optimization problems (POPs) is known to be equivalent to the sparse SDP relaxation by Waki et al. with relaxation order 1, except the size and sparsity of the ...
متن کاملRSS-based Localization in Wireless Sensor Networks with Unknown Transmit Power and Path Loss Exponent using SDP Relaxation
This paper addresses the problem of locating multiple target nodes from noisy received signal strength (RSS) measurements in wireless sensor networks (WSNs), for the case where the transmit power and the path loss exponent (PLE) are simultaneously unknown. According to the conventional path loss model, the maximum likelihood (ML) estimator is derived by solving the nonlinear and nonconvex least...
متن کاملA multi-hop PSO based localization algorithm for wireless sensor networks
A sensor network consists of a large number of sensor nodes that are distributed in a large geographic environment to collect data. Localization is one of the key issues in wireless sensor network researches because it is important to determine the location of an event. On the other side, finding the location of a wireless sensor node by the Global Positioning System (GPS) is not appropriate du...
متن کاملOptimizing the Event-based Method of Localization in Wireless Sensor Networks
A Wireless Sensor Network (WSN) is a wireless decentralized structure network consists of many nodes. Nodes can be fixed or mobile. WSN applications typically observe some physical phenomenon through sampling of the environment so determine the location of events is an important issue in WSN. Wireless Localization used to determine the position of nodes. The precise localization in WSNs is a co...
