CAD-MAC: Coverage Adaptive Directional Medium Access Control for mmWave Wireless Personal Area Networks

摘要

Directional antenna is essentially recommended to use in 60 GHz band communication due to the characteristics of high path loss and short communication range. However, a number of directional antenna related researches have been considered to cover just the only specific service region. Therefore, in this paper, we propose a coverage adaptive directional MAC (abbreviated to CAD-MAC) for mmWave WPAN that dynamically assigns a sector based on variable device locations. CAD-MAC provides higher throughput and energy efficiency. It can also cover every devices placed in a certain area. To evaluate its performance, we compare CAD-MAC with the existing MAC protocols in general service model.
