Abstract:

In a wireless personal area network (WPAN) consisting of a coordinator and multiple nodes, the coordinator determines which communication link between nodes to be activated, because multiple links cannot be activated simultaneously owing to an interference from each other. However, if nodes in a WPAN use a millimeterwave (mmWave) and the beamforming technique which forms the beam in the desired direction, the coordinator can select multiple links to be activated. This is because mmWave signal with beamforming technique shows narrow beam width and high directionality, and thus, interference to the undesired direction is considerably low. To improve the network performance by activating multiple links simultaneously, the methodology for scheduling multiple links has been an important issue in a mmWave wireless network. In this paper, we study the mmWave link scheduling problem for a mmWave WPAN following an IEEE 802.15.3c standard. The proposed method adjusts weight for selection of each link based on the queue length information, and schedules links by using the adjusted weights and transmission rates. The weight is adjusted by employing a hybrid approach of linear and equal weight determinations. Through extensive simulation results, we verify the network throughput and stability performance of the proposed link scheduling method.
