A New Proposed the Internet of Things (IoT) Virtualization Framework Based on Sensor-as-a-Service Concept

摘要

The Internet of Things (IoT) is a new telecommunication paradigm to enable the remote connectivity between dozens of smart objects so that any physical object can interact with each other unmanned-wise. The innovative design for the IoT paradigm has mainly based on "Virtualization technology" to provide the full interaction for the user within the system environment. Meanwhile, it alleviates potential system complications. In this end, this paper seeks to introduce a new vision of an IoT virtualization framework based on Sensor-as-a-Service (SenaaS) to maximize the utilization of sensor functionalities. Moreover, the paper offers an adaptor oriented structure technique by using ITA Sensor Fabric (aka Information Fabric) which relies on Publish/Subscribe mechanism to realize an oriented communication between things. In our proposed framework, ITA Sensor Fabric used as a parallel measure with the semantic approach for mitigating the principle issues in the sensor arena. Furthermore, the proposed framework uses Backtracking Search Optimization Algorithm (BSA) to enhance the SenaaS performance with the time-sensitive services and ensure the required level of the Quality of Service (QoS). The effectiveness of the proposed framework tested by using MATLAB and NS2-based simulations in terms of delay time, packet delivery ratio, throughput, and jitter. Finally, all the experimental results proved that BSA has a significant influence on the time-sensitive services more than their analogues of algorithms.
