Abstract :
In the article it demonstrated that the neighbor-finding procedure in many nowadays wireless sensor networks bears a potential of generating an excessive radio interference. It is shown, based on Stojmenovič Minimum Spanning Tree algorithm, that the situation can be improved even in the worst case scenario of simultaneous transmission from all network nodes, by utilizing the directional antennas, taking the Signal-to-Noise and Interference ratio as a performance measure.
