Smart neighbor scanning with directional antennas in 60 GHz indoor networks

The 60 GHz technology has an immense potential to provide wireless communication at multi-gigabit rates. At 60 GHz frequency band, severe attenuation of the signals can significantly degrade communication performance. To cope with the attenuation problem, directional antennas with high directive gains can be utilized. When network nodes use directional antennas, the neighbor discovery process becomes more complicated and time consuming. To reduce the neighbor discovery time, we propose a smart neighbor scanning algorithm in this paper. It is observed that the proposed strategy discovers 70% of the links 81% faster and 90% of the links 15% faster than random scanning strategy.
