Title: Analysis and Optimization of Caching in Large-scale Wireless Networks （大规模无线网络缓存分析及优化）
Abstract: The rapid proliferation of smart mobile devices has triggered an unprecedented growth of global mobile data traffic. Modern data traffic exhibits a high degree of asynchronous content reuse. Thus, caching at base stations (BSs) is gradually recognized as a promising approach to support massive content delivery over wireless networks. It is of critical importance to fully exploit the potential of caching in wireless networks, by jointly utilizing other key wireless technologies. In this talk, I will discuss joint caching and multicasting in heavy or moderate load scenarios, and joint caching and BS cooperation in light load scenarios. This talk will present a general framework of analysis and optimization of average performance in large-scale cache-enabled wireless networks, which is based on stochastic geometry, probability theory and various optimization techniques. The analysis and optimization results provide valuable design insights for practical cache-enabled wireless networks.
