| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A network topology is the logical structure of a communication network consisting of a large number of nodes (e.g., hosts and switches/routers) and links connecting among those nodes. Every communication network (e.g., Ethernet-based networks, TCP/IP networks, wireless networks, DTN (Delay/Disruption-Tolerant Networking), and ICN (Information-Centric Networking)) has a different network topology, depending on the features and capabilities of nodes (e.g., the maximum number of ports/interfaces and the tolerance to a network loop) and links (e.g., unidirectional/bidirectional, wired/wireless, and the maximum length) as well as several physical restrictions and usage patterns. Since a network topology is a sort of graphs, in the literature, it has been actively studied from theoretical and mathematical viewpoints in the field of graph theory and recently in the field of network science. In a communication network, not only the characteristics of the network topology itself (e.g., size, density, degree distribution, diameter, and connectivity), but the characteristics of communications performed on it (e.g., speed, quality, efficiency, availability, and reliability) are also important. This paper introduces four research topics recently published by our research group, each of which reveals the impact of the network topology on the characteristics of a dynamical process such as information search, delivery, and diffusion in a different context. |
