| Abstract(in English) | As a result of rapid development in wireless communications and computer hardware technologies, currently, we can access various information from anywhere using portable terminals with wireless communication capabilities. To support the integration and the use of data held by mobile hosts in this environment, we have proposed and implemented AMDS (Active Mobile Database System) as the kernel system for data and mobile host management in mobile enviromnents. ECA rules, the behavior definition language of AMDS, have high description capability that enables users to define complicated behavior. However, the execution of ECA rules may fall into a chain of unexpected behaviors. In general, a directed graph called trigger graph is used for detecting illegal chains. Unfortunately, trigger graphs highly depend on network topology, thus it is difficult to employ trigger graphs in mobile computing environments. Therefore, we have proposed a method that could reconstruct trigger graph dynamically. In this paper, we implement our method on AMDS and evaluate it by simulation studies. |
