                          學術報告一:Social Group Utility Maximization Game: A New Paradigm for Mobile Social Networks
                          Mobile traffic is projected to continue growing rapidly in the foreseeable future. Different from other networks (e.g., sensor networks), a salient feature of mobile networks is that mobile devices are carried and operated by human beings. With the explosive growth of online social networks, social relationships are shaping people’s interactions in an unprecedented manner. With this insight, we develop a social group utility maximization (SGUM) game framework that takes into account both social coupling and physical coupling among mobile users. Under the SGUM framework, each user aims to maximize its social group utility, defined as the weighted sum of the individual utilities of the users that have social ties with it. One distinctive merit of the SGUM framework is that it provides a unifying platform to capture complex social structure among mobile users, consisting of diverse “positive” and “negative” social ties, and hence it offers rich flexibility in modeling and understanding the rich continuum from zero-sum game (ZSG) to  non-cooperative game (NCG) to network utility maximization (NUM) - traditionally disjoint paradigms for network management.  We will also touch upon related privacy and security issues.

                          學術報告二:Cyber-Physical Security in Future Cities
                          Digital control and communication are being used to modernize urban infrastructures, such as electrical grids and water systems, to meet the increasing demands of future cities for size, performance, and sustainability. While the added intelligence provides desirable performance features, it also adds to the system's complexity, which raises equally critical concerns for safety and security. In this talk, I will overview research that analyzes cyber-physical system (CPS) vulnerabilities such as real-time consumer pricing in emerging smart-grid demand response. I will also propose a design methodology to monitor the (not fully trustworthy) high performance operation of a smart grid, but assure its fallback to a simple and safe operation mode when the system drifts too close to unsafety.

                          學術報告三:Real-Time Intrusion Detection for Multimedia Applications over Wireless Networks
                          With the increasing coverage of the IEEE 802.11 based wireless networks, the voice/video multimedia applications over wireless networks are drawing more interest in both academia and industry. Due to the openness and distributed nature of the protocols utilized by the technologies, it becomes easy for malicious users on the networks to achieve their own gain or disrupt the service by deviating from the normal protocol behaviors. The stringent QoS requirements of the multimedia applications require us to detect the malicious behavior in real time after it occurs. In this talk, we present our recent studies on real-time intrusion detection techniques that can quickly track down the malicious behaviors which take advantage of vulnerabilities from either upper-layer signaling protocols or the underlying 802.11 protocols. While existing detection schemes mainly depend on heuristic parameter configuration and experimental performance evaluation, which largely limits the flexibility and robustness of those schemes, we develop an analytical model to theoretically study the performance of our detection scheme and guide the detection system configuration for guaranteed performance.

                          學術報告四:Locating Contagion Sources in Networks
                          Who leaked classified information or started a rumor on online social networks? Who uploaded contraband materials to the Internet? Where are the sources of epidemics? These questions are of great importance to the world’s safety and security, but are difficult to answer. In this talk, I will introduce a sample path based approach, which is to identify the most likely sample path and view the source of the optimal sample path as the information source. I will present some recent results based on the sample path based approach, including fundamental theories, high performance algorithms, and evaluations using real world networks.
