| Research Abstract |
In this research, we have developed a simulation framework that simulates mobile and ubiquitous networking systems with realistic pedestrian and vehicle mobility in urban environment. This allows developers to predict and evaluate the impact of those ubiquitous computing and communication capability on the activities of pedestrians and movement of vehicles. First, we have proposed an abstraction method for the MAC layer to improve scalability of wireless network simulation. In order to model urban environment in a realistic way, we have proposed a simulation middleware that is able to read digital map data and to generate realistic mobility. Using those systems, we can comprehensively and efficiently evaluate the system performance and capabilities. We have also proposed a method to efficiently reduce the total amount of exhaustive test scenarios required for target system validation and performance verification under different environmental settings
