Qos-Driven Architectural Mining for Publish/Subscribe Systems Deployed on MANET

An important issue in distributed systems is to improve the information dissemination, especially in the Publish/Subscribe systems deployed in mobile ad hoc networks (MANET). In fact, the achievement of this goal needs to take into account various problems such as the failure of the communication system and the degradation of the quality of service (QoS). We focus on QoS problem, we address possible solutions to ensure efficient and reliable communication systems. We propose reconfiguration actions rules which are applicable to a network having QoS degradation. We use graphs to model the distributed system and graph transformation engine (GMTE) to execute rules of reconfiguration. The generated solution is selected according to various evaluation criteria in order to satisfy the requirements of system in terms of QoS.
