[Retracted] Mobile Internet of Things Dynamic Grid QoS Service Matching Mechanism and Simulation Analysis

Abstract

With the development of the mobile Internet of Things, people have higher and higher requirements for services, and how to provide high-quality services that meet the needs of users has also become a hot issue of current research. This article is also in the context of the mobile Internet of Things, researching the solution to the service matching problem. In order to provide high-quality grid services, the grid system needs the support of quality of service (QoS). Based on the existing QoS matching strategy, a service matching strategy based on dynamic grid QoS is proposed. This paper combines semantic information, considers service quality QoS and user preferences, and improves the success rate of service matching through hierarchical matching, so as to provide users with high-quality services. At the same time, the classic Max-Min algorithm in grid task scheduling is analysed, and on this basis, the impact of QoS on task scheduling is fully considered, and combined with the concept of execution cost, a grid task based on QoS constraints (MOS) is proposed. Through simulation verification and analysis, the strategy in this paper not only achieved higher matching performance, but also improved the success rate of task execution, and the effect of system load balancing was also significantly improved.

Policy-driven Data Sharing over Attribute-Based Encryption supporting Dual Membership

“…Nowadays, many novel technologies, e.g., Internet of things (Fan, 2021b), cloud computing (Li et al, 2021a,b;Shantharajah and Maruthavani, 2021), improve the efficiency of data sharing, and enable data sharing more and more widespread in people's daily lives. However, how to overcome the security risk of private data is a popular challenge currently.…”
