This paper presents an algorithm for estimating the network connectivity of a wireless network from physical layer measurements. Received signal strength (RSS) data is used to jointly estimate the locations and radiation patterns of multiple transmitters. These estimates are used to create an RF footprint of each transmitter, and the collection of footprints can be used to estimate which nodes are...
In this paper, we study the issue of defending against a wireless sensor network (WSN) that has been deployed by a malicious enemy agent in an area of interest to us. While there can be many approaches to defend against maliciously deployed WSNs, we propose the design of a localization centric approach. Specifically, the problem we address is: given an enemy deployed WSN in an area of interest to...
Multidimensional scaling (MDS) has been recently applied to node localization in sensor networks and gained some very impressive performance. MDS treats dissimilarities of pair-wise nodes directly as Euclidean distances and then makes use of the spectral decomposition of a doubly centered matrix of dissimilarities. However dissimilarities mainly estimated by received signal strength (RSS) or by the...
