세미나 제목 : Predictive handover for mmWave and stochastic geometry anslysis of channel adaptive scheduling

발표초록 : In this talk, I will introduce two topics related to resource management in wireless networks. The first topic is a proactive handover based on human blockage prediction using RGB and depth (RGB-D) cameras to substantially alleviate the human blockage problem in mmWave communications. Using IEEE 802.11ad-based devices, experimental results demonstrate that the proactive handover system can considerably reduce the duration of human blockage-induced degradation of throughput.

The second topic is stochastic geometry analysis of channel-adaptive scheduling. The coverage probability of normalized SNR-based scheduling in a downlink cellular network is derived by modeling the locations of the base stations and users as two independent Poison point processes. In particular, when the desired signal experiences Rayleigh fading, the coverage probability is shown to be given by a series of Laplace transforms of the probability density function of interference. Also, a closed-form expression for the coverage probability is approximately achieved.
