By Year By Research Group | In passive target localization using direction finding (DF), there are particular sensor-target placements that cause large biases in the estimates or the failure of estimates to converge to a unique solution. Identification of such problematic ... Because of the simpleness, robustness and accuracy, sonar sensing has wide applications in navigation, target tracking and distance estimation for both civilian and defence use. This paper presents the applications of sonar sensors in the area of ... Abstract—In this paper, we study the well-known phase transition behavior of connectivity in a wireless multi-hop network, but, in contrast to other studies, in a shadowing environment. We consider that a total of n nodes are randomly, independently ... Location information for sensors in wireless sensor networks (WSNs) is essential to many tasks. In the presence of noise, locations must be estimated and thus the errors are unavoidable. Moreover, the errors can propagate (i.e. increase) as sensors ... In this paper, we study the transmission power to secure connectivity of a network. Instead of requiring all nodes to be connected, we require only that a large fraction (e.g. 95%) be connected, termed the giant component. We show that with this ... Relay technologies have been actively studied and considered in the standardization process of next generation mobile broadband communication systems. This paper first introduces and compares different relay types in 3GPP LTE-Advanced and WiMAX standards.... In this paper we report some new results obtained in the field of multi-agent systems that are based on convex optimization. First, we provide review of a set of polynomial function optimization tools including sum of squares (SOS) and semidefinite ... In this paper we propose a method for enhancing synchronizability using convex optimization. This method is based on adding new edges to the network, later the performance of the proposed method is tested through providing some numerical examples. ... |
