A distributed nodes´ localisation approach in Wireless Sensor Networks

Node location is of main importance for several areas of applications based on Wireless Sensor Networks (WSNs), for instance location-based services. In this paper, we propose a new distributed approach for nodes´position estimation based on distance measurements. Our approach is close to the cooperative approach based on Curvilinear Component Analysis (CCA) proposed in. The complexity of the proposed approach is O(N) for all the network, but as the approach is distributed, the computation time is quasi-constant per node in the network.
