講學(xué)題目1: 5G and Integrated Terrestrial-Satellite Communication Networks

講學(xué)時(shí)間：2019.01.15上午 9:00-10:30

講學(xué)地點(diǎn)：哈工大科學(xué)園2A棟1013會(huì )議室

報告內容簡(jiǎn)介：

5G wireless networks are expected to support extremely high data rates and radically new applications, as well as extensively wide coverage. Although the terrestrial cellular networks have dominated the mobile users from 3G to 4G, the gap between the demand and supply is becoming more and more prominent. Satellite network is an ideal solution to address such a dilemma. While the terrestrial networks can achieve high-speed data services at low cost, satellite based access is one way to complement terrestrial based networks to ensure ubiquitous, 100% geographic coverage. Satellite communication networks are emerging in recent years, which are able to provide super wide coverage and high capacity. Therefore, the integrated Terrestrial-Satellite Communication networks (TSC) is a quite promising solution for future 5G networks. In this talk, we discuss a range of technical issues in TSC, from spectrum sharing to multiple access resource allocations, as well as an overview some of the most recent systems.  

講學(xué)題目2:  Recent Advances and Challenges in Security for 5G Systems

講學(xué)時(shí)間:2019.01.15上午 10:45-12:15

講學(xué)地點(diǎn)：哈工大科學(xué)園2A棟1013會(huì )議室

Wireless communication technologies are ubiquitous nowadays. Most of the smart devices have Cellular, Wi-Fi, Bluetooth connections. These technologies have been developed for many years, nonetheless they are still being enhanced. More development can be expected in the next 5 years, such as faster transmission data rate, more efficient spectrum usage, lower power consumption, etc. Similarly, cellular networks have been evolved for several generations. For example, GSM as part of 2G family, UMTS as part of the 3G family, and LTE as part of 4G family. In the next few years, 5G cellular network systems will continue the evolution to keep up with the fast-growing needs of customers. Secure wireless communications will certainly be part of other advances in the industry such as multimedia streaming, data storage and sharing in clouds, mobile cloud computing services, etc. This talk covers the topics on security for next generation wireless networks, with focusing on 5G wireless network systems, followed by a discussion on the challenges and open research issues in the area.

講學(xué)題目3:  Physical-Social-Aware D2D Content Sharing Networks: A Provider-Demander Matching Game

講學(xué)時(shí)間：2019.01.15 下午14:30-16:00

報告內容簡(jiǎn)介：

Device-to-device content sharing is widely considered as an effective response to the prevalence of multimedia content sharing and local services. To ensure its advantages, how to optimally match potential providers to demanders of contents is of importance, especially considering the randomness of content location, as well as the coexistence of altruistic, selfish, and even malicious user behaviors. Accordingly, for such a matching process, it is advisable to achieve a win-win solution, rather than sacrificing performance of either potential providers or demanders. In this work, we employ the weighted directed graph theory to model the two-sided physical-social-aware preferences, which jointly exploit the physical and social networking characteristics of both sides. Then, we study the two-sided physical-social-aware matching problem, which essentially involves the joint issue of pairing scheduling and power control with respect to potential providers and demanders. To solve it in a tractable manner, the former is cast as a two-sided one-to-one matching game, in which the potential providers and demanders rank one another by using the proposed preferences, and the latter is transformed into the preference profile establishment of this matching game. Finally, a distributed algorithm based on the Dinkelbach iteration and deferred acceptance approaches is developed. The properties of the resulting stable outcomes are then studied, and the simulation results verify the availability and efficiency of the proposed algorithm.
