    Conceptual Approach Towards Stateful Computation Offloading in Resource Constraint Android Devices
    (KDU IRC, 2017) Vekneswaran, P; Dissanayake, N. R
    Cyber Foraging is an approach to resolve the performance and resource limitations of small portable hand-held devices, through offloading heavy processes to nearby stationary devices called Surrogate Devices, which have more computation capabilities. The way the Cyber Foraging is mostly tackled by invoking a remote method in the Surrogate Device – which contains the application related information as a pre-requisite – at the time of local invocation, in a state-less manner. This limits the possibilities where the Cyber Foraging can be used in statefull context, which can provide maintenance of state which will help the developer to transmit state of objects used inside the offload candidate so it won’t differ from local execution and remote execution. In order to use in a stateful manner, researchers have used a virtualisation approach, which is a resource consuming approach. As an alternative, we propose a conceptual solution to transmit state from mobile platform to the surrogate platform, without having to deploy a mobile OS virtual machine into the surrogate environment. The concept will address all the drawbacks of virtualisation and provide the similar benefits at a lower resource cost in the Surrogate end

    Cybersecurity and Network Performance Modeling in Cyber-Physical Communication for BigData and Industrial IoT Technologies
    (IEEE, 2019-07-26) Sen, S; Jayawardena, C
    The information and networking technology have been revolutionized with the inception of recent evolution of Cyber-Physical Systems (CPS) and the Internet of Things (IoT). The next generation distributed computing systems i.e., CPS and IoT are highly interconnected and deeply embedded with the physical world. By capitalizing the advantages and opportunities of these technologies, Industrial-IoT has been fueling smart industrial processes. The execution and application of these processes generate huge amount of data, which leads the distributed computing systems to carefully consider information and data management reliably and securely; also facilitating the necessary automation as well as ensuring timely information exchange. But the current internet doesn't guarantee the network performance and secure transportation; in addition the physical systems are becoming more insecure when interconnected to the cyber systems. These bottlenecks are leading to the necessity of improving performance and security in the cyber-physical communication. Considering those pervasive requirements, this paper has modeled network performance as well as system security with a view to improve these components which could heel the reliable cyber-communication challenges.
