| 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 handy 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 environment. The behavior definition language of AMDS, ECA rules, 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 chains. Unfortunately, trigger graph highly depends on network topology, thus it is difficult to employ trigger graph in mobile computing environment. In this paper, we propose a method that could reconstruct trigger graph dyanmically to adapt to changes in network topology. By using this mechanism, mobile applications with ECA rules can be used more safely. |
