Performance evaluation of distributed NoTA applications on multi-core platforms

For future applications running on nomadic devices operating in smart spaces, the availability of the services and the quest for better alternative services will go hand in hand to enable the best-possible experience for the end-user. To realize it, a service-level interoperability solution must be devised that would enable applications to access services over heterogeneous platforms and various transport technologies. The recent extension of the Network-on-Terminal-Architecture (NoTA) supports service-level interoperability between mobile devices via a device interconnect protocol (NoTA DIP), enabling applications to access and discover services over multiple transport technologies in a seamless manner. A brisk performance evaluation phase is required for evaluating the feasibility of new NoTA applications on modern multi-core based mobile device platforms. To achieve this goal, NoTA Service Oriented Architecture (SOA) application components. i.e., Application Nodes (ANs) and Service Nodes (ANs) are first refined to encompassing processes and then to platform services and functions to form a layered application architecture. In next step, the NoTA SOA application model layers are mapped to ABSOLUT workload model layers employed in performance simulation. Furthermore, the ABSOLUT workload models corresponding to different NoTA DIP implementations for example NoTA DIP kernel implementation and NOTA DIP Daemon mode must be modeled and integrated to ABSOLUT. The approach is experimented with a case study. The modeled components and approach is not limited to NoTA SOA and can be used for the performance evaluation of other distributed service oriented application architectures. MARTE UML2.0 profile, Papyrus UML 2.0 modeling tool and SystemC were used for modeling and simulation.
