Abstract

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 [13]. 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.
