| 題目(Title) | Resource Sharing in Challenged Opportunistic Environments |
| 概要(Abstract) | Opportunistic networks are characterized by the dynamic connectivity created when mobile devices encounter each other, as they are within close proximity. During these transient opportunities, devices are typically within one-hop wireless range of their neighbors. We propose spatio-temporal reachability graphs to depict reachability of time- and space-sensitive content in opportunistic mobile environments. Furthermore, we develop analytical frameworks to estimate opportunistic paths, service composition and content distribution in such environments. We perform extensive trace-driven simulation studies to determine content dissemination properties of environments with known mobility patterns. Proposed schemes are useful to service/content providers as well as receivers. |

| 講演者紹介(Introduction of Lecturer) | Mohan Kumar is a professor and the chair of the Department of Computer Science at the Rochester Institute of Technology. Prior to 2013, Mohan Kumar held faculty positions at the University of Texas at Arlington and the Curtin University, Perth, Australia. Mohan Kumar received the BE degree from Bangalore University, India in 1982, and the MTech and PhD degrees from the Indian Institute of Science in 1985 and 1992, respectively. Mohan’s current research interests include pervasive and mobile computing and parallel and distributed computing. He has published more than 180 articles in refereed journals and conference proceedings, and supervised 17 doctoral dissertations and 32 MS theses in the above areas. He has developed or co-developed: algorithms/architectures for service composition in pervasive environments; information acquisition, dissemination and processing in pervasive and sensor systems; and caching and prefetching in mobile, distributed, pervasive, and P2P systems. Mohan is one of the founding editors of the Elsevier’s Pervasive and Mobile Computing Journal and is one of the area editors of Computer Communications. He is a co-founder of the IEEE International Conference on Pervasive Computing and Communications (PerCom) and is the current Steering Committee Chair for IEEE PerCom. |
