| Research Abstract |
In ubiquitous society of the near future, we need to realize flexible interoperability across multiple networks such as wireless communication networks, mobile phone networks, sensor networks and vehicle-to-vehicle communication networks, in order to provide several types of information services depending on surrounding environments, positions of terminal holders and their preferences. In this study, we have designed a method for building realistic mobility models of pedestrians and vehicles in urban environments, and developed a technology to achieve a test-bed for rapid evaluation with a low cost. We have also developed a system for recording and collecting automatically radio interference situations in the test-bed. Then, we have developed an emulation technology for the performance evaluation of heterogeneous large-scale network services based on the obtained radio interference situations in the test-bed using a hierarchical simulation technology.
