A novel approach for localisation based on Wi-Fi

IEEE 802.11b standard, also known as Wi-Fi, is one of the most used wireless communication systems. Location of a mobile user by IEEE 802.11b has a lot of advantages, mainly due to the use of the same hardware/software needed for the communication. Literature presents many approaches for localisation based on Wi-Fi; among them there is the pattern matching algorithm. The paper aims to present outdoor use of this algorithm, due to the lack in literature of relevant examples. Further, the paper will present a new approach for wireless localisation, aimed to reduce the complexity of the pattern matching algorithm.
