Professor Xin Wang Visited our Group

Professor Xin Wang visited our group on Jun 18, 2013 and gave a talk entitled "SMCLOUD: Social Mobile Cloud".


Despite the great technical advances, mobile devices are still limited in their capabilities of supporting rich media and computation intensive applications due to their constraints in memory, CPU and battery power. One solution to overcoming resource limitations in mobile devices is to exploit mobile cloud computing. By leveraging the resources of cloud, computation expensive tasks can be offloaded to the cloud, which helps to conserve the energy of mobile devices and offers great opportunities for mobile devices to run advanced software and applications. However, the limited wireless bandwidth and high latency in wide-area wired and wireless networks pose practical challenges to running wireless applications in remote cloud servers. Instead of relying on remote clouds, we consider a mobile cloud computing system which exploits resources from local cloudlets or mobile devices. However, the amount of local resources is generally much smaller than that of remote large-scale cloud and application arrivals are more dynamic. In order to accommodate more mobile applications within the given resource limits, we propose a social mobile cloud (SMCloud) platform which takes advantage of the features of social networks to significantly increase the number of applications that can be supported. This in turns helps to increase the capability of mobile devices in supporting media-rich applications and reduce their energy consumption. In this talk, we will present some techniques we have developed for SMCloud and briefly introduce other research directions of our group.


Dr. Xin Wang is currently the director of the Wireless Networking and Systems (WINS) lab of the department of Electrical and Computer Engineering of the State University of New York (SUNY) at Stony Brook. Prior to joining Stony Brook university, she was an assistant professor in the department of computer science and engineering of SUNY at Buffalo between 2003 and 2005, and was a Member of Technical Staff in the area of mobile and wireless networking at Bell Labs Research, Lucent Technologies, New Jersey between 2001 and 2003. While in Bell-Labs, she served as the QoS subsystem architect for the Lucent Imminent Content Switch project, cross-team consultant for Lucent Metro Ethernet Project, and technical lead in QoS management in Lucent 3G Radio Network Controller project.

Dr. Wang has been conducting and leading research work in the design of network architectures, protocols and algorithms. Her research areas have expanded from the core Internet research, to the current focus on wireless network infrastructure design with the major goals of significantly improving wireless network capacity, reliability, and scalability, supporting advanced wireless applications and services. Her interest areas also include mobile computing and distributed computing.

Dr. Wang has been continuously serving in technical committees and executive committees of major conferences in networking and computing areas, including MobiCom, Infocom, ICDCS, and PerCom.

Dr. Wang received her PhD degree from Columbia University. She is a recipient of the prestigious NSF (National Science Foundation) CAREER award in 2005, and ONR (Office of Naval research) Challenge award in 2010.
