Enabling Exclusive Shared Access to Cloud of Things Resources

Cloud of Things (CoT) is an emerging paradigm that integrates Cloud Computing and Internet of Things (IoT). CoT is constrained by the limited computing capabilities of IoT resources and the costly investment required to deploy IoT infrastructure. Despite the support of existing CoT implementations to various applications, IoT physical resources are still computationally limited and cannot to be shared as other Cloud resources yet. This paper proposes a new approach to improve shared access to IoT resources. The new approach relies on optimising resource trading of IoT resources to enable exclusive access to allocated resources at a given time. A generic architecture is proposed to support the proposed approach along with notations required to commoditise IoT resources. A case study of multiple application uses is presented. Simulations are carried out to evaluate the feasibility of the approach using three optimisation techniques. The evaluation of the proposed approach includes optimising the cost of resource allocation, different QoS metrics and the coverage of IoT resources.
