To localize multi-hop wireless sensor networks (WSN) nodes, only the hop-based information (i.e., hops' number, average hop size, etc.) have been so far exploited by rangefree techniques, with poor-accuracy, however. In this paper, we show that localization accuracy may greatly benefit from joint exploitation, at no cost, of the information already provided by the forwarding nodes between each anchor...
In wireless sensor networks (WSNs), estimation of the true distance between a source and its destination based on the hop counts between them is an important research problem. The basic idea of several hop-count-based distance-estimation algorithms is to seek an analytical/heuristic transformation from the observed destination's hop-count information to an unknown source-to-destination distance (s2d-distance)...
