Method on fast DOA estimation of moving nodes in ad-hoc network

In this paper, a new algorithm to fast estimate moving nodes in ad-hoc network was proposed. Instead of the independent estimation at different time of the conditional DOA algorithms, we take full use of the previous results to provide the latter information on the DOA of the nodes, which could greatly speed up the following estimations. Therefore, the algorithm could keep up with the moving nodes more quickly. Simulation results showed the new method was timesaving.
