Abstract :
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.
