Description

The combination of service-oriented applications, with their run-time service binding, and mobile ad hoc networks, with their transient communication topologies, brings a new level of complex dynamism to the structure and behaviour of software systems. This complexity challenges our ability to understand the dependence relationships among system components when attempting to perform analyses such as fault localization. Current methods of dynamic dependence discovery, developed for use in fixed networks, assume that dependencies change slowly. Moreover, they require relatively long monitoring periods as well as substantial memory and communication resources, which are impractical in the mobile ad hoc network environment. The existing system focus on statically structured systems operated in fixed network. The methods can assume no practical limits on the storage, computational, and communication resources needed to support those statistical techniques. In this project the system proposed a new dynamic dependence discovery method designed specifically for this environment, yielding dynamic snapshots of dependence relationships discovered through observations of service interactions. The system introduce our dependence discovery method and evaluate its sensitivity to a distinguishing aspect of the MANET environment, namely time-dependent behavior. The system approach is based on the use of monitors deployed onto the mobile nodes. The system have formulated a relatively simple dependence discovery method that is nonetheless more suitable for services operating in the challenging MANET environment.
