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)...
In WSNs (wireless sensor networks), a source node sends its packets via multi-hop relays to a destination node if the source cannot communicate with the destination directly. Estimation of the Euclidean distance between the source and its destination is an important research issue. Among many other distance estimation techniques, the one based on the hop-count information has attracted a lot of research...
Localization is one of the most important research issues in wireless sensor networks (WSNs). Hop-count based localization has been proposed as a cost-effective alternative to the expensive hardware-based localization schemes. In this paper, we propose a new method to estimate distances between anchors and nodes based on hop-count information. Localization is then achieved using the estimated distances...
