Dynamic Multi Layer Management of Service Based Systems in Hybrid Wireless Networks

The management of large scale service based systems hosted in dynamic environments of hybrid wireless networks is a complex task. Such systems are designed as composite services integrating heterogeneous service components such as sensor, software and data services. In this paper, we propose a new situational aware framework which allows the network operators to effectively manage such complex systems. The framework integrates three key components. The Service Placement component and the Configuration Service which collectively arrive at decision about placements and compositions of the services. An instrumental element of the framework is the Policy Based Management System providing the network operators with a tool to dynamically control these mechanisms. 1
