Abstract:
Locating nodes is a fundamental problem in wireless networks with hundreds of devices deployed in a wide area. This is especially relevant for mobile nodes. Wireless sensor nodes are usually powered by small batteries, solar panels or piezoelectric generators, so that, and consequently, power consumption is the main constraint to deal with. But classic localization techniques do not consider the problem of energy consumption as a key point. This paper presents a novel low power and range-free localization technique based on
distributed fuzzy logic and cooperative processing among a set of fixed nodes and its neighbours. This feature permits better accuracy with less power consumption than most relevant localization techniques.
