We have designed a novel positioning system, the Cooperative Location-sensing system (CLS) that employs the peer-to-peer paradigm and a probabilistic framework to estimate the position of wireless-enabled devices in an iterative manner without the need for an extensive infrastructure or time-strenuous training. CLS can incorporate signal-strength maps of(More)
We propose a new localization method in order to estimate the position of wireless devices in real time, using already existent infrastructure (such as IEEE 802.11 access points). We present a filtering algorithm that computes the most likely path taken by a mobile node, based on signal strength measurements and a known signal strength map. In our approach(More)
