Reliable service availability and access control method for cloud assisted IOT communications

Information access and retrieval from cloud resources in an Internet of Things (IoT) paradigm is a challenging task due to synchronization and availability issues. IoT devices and user equipment access resources in a ubiquitous manner irrespective of time and resource availability. To address the synchronization issues in resource availability and accessibility, this article introduces reliable service availability and access control (RSA2C) method. In this method, the available resources are scheduled for serving incoming requests on the basis of service time. Prior to the scheduling process, the requests are classified as overlapping and non-overlapping to reduce delays and backlogs. The gateway accessibility process is capable of accepting and processing incoming requests by evaluating the minimum processing time to select a reliable gateway. This time-based selection aids in improving the response rate. The occupancy factor of the gateway is estimated for admitting requests to the cloud layer. A specific weight factor is used for differentiating gateways on the basis of cost and occupancy factor, to improve the accuracy of selection. The non-overlapping requests are handled using optimal gateways and the other requests are processed in a recurrent manner. As the request processing follows sequential processing recurrently, the delay in transmission and drops i.e. the backlogs are prevented. The distinct methods are incorporated in the gateway and cloud layers for achieving reliable communication estimated using the metrics bandwidth, resource utilization ratio, pause time, delay and backlogs.

Automated summary

This article introduces a reliable service availability and access control method (RSA2C) to address the synchronization and availability issues in accessing cloud resources in an IoT paradigm. The method improves selection accuracy by evaluating gateway occupancy factor and using different weight factors, thereby enhancing communication reliability.
