Title: Optimizing Mixture Importance Sampling and Online Learning for Network Simulations

Importance sampling (IS) is widely used in rare event simulation, but it is costly to deal when there are many simultaneous rare events For example, a rare event can be the failure to provide the quality-of-service guarantee for a critical network flow. Since network providers often need to deal with many critical flows (i.e., rare events) simultaneously, if using IS alone, providers have to simulate each rare event with its customized importance distribution individually. To reduce such cost, we propose an efficient mixture im- portance distribution for multiple rare events, and formulate the mixture importance sampling optimization problem (MISOP) to select the optimal mixture. We first show that the “search direction” of mixture is computationally expensive to evaluate, making it challenging to locate the optimal mixture. We then formulate a “zero learning cost" online learning framework to estimate the “search direction”, and learn the optimal mixture from simulation samples of events. We develop two multi-armed bandit (MAB) online learning algorithms to: (1) Minimize the sum of estimation variances with a regret of (lnT)2/T; (2) Minimize the simulation cost with a regret of 􏰍ln(T)/T , where T denotes the number of simulation samples. We demonstrate our method on a realistic network and show that it can reduce the cost measures (i.e., sum of estima tion variances and simulation cost) by as high as 61.6% compared with the uniform mixture IS.

Title:Trends and Future Perspective for 5G and 6G Networking

Abstract: 5G is now being deployed in many countries. The new connected end points of communication networks will play key roles in 5G era, such as autonomous vehicles, various smart sensors and IoT, as well as the enhanced Internet and any other existing communications devices. Various research initiatives have started in academia, industry, and standard bodies toward 6G mobile wireless networks.
This talk reviews trends in Global ICT and describes 5G architecture and use cases, and then addresses possible technical pillars of 6G, which are enhanced 5G technologies and/or new technologies possibly to be adopted in 6G.  It also discusses the issues and challenges in realization and in deployment as an infrastructure.
