Abstract
In this paper we propose a distributed algorithm for solving the positioning problem in ad-hoc
wireless networks. The method is based on the capability of the nodes to measure the angle of
arrival (AOA) of the signals they produce. The main features of the distributed algorithm are
simplicity, asynchronous operations (i.e. no global coordination among nodes is required), ability to
operate in disconnected networks. Moreover each node can join the computation at any time.
Numerical results, obtained by simulating several scenarios, show that the algorithm can reach a
good level of convergence even when the number of communications is limited.
