Low-latency, real-time rendering of 3D objects is critical for mobile web-based augmented reality (MWAR) applications. While cloud-based or edge-based server rendering offloading can reduce the latency for mobile devices, a high volume of user requests in user aggregation scenarios can overload servers and transmission channels. It can result in a poor user experience due to resource consumption and high latency. This paper presents a decentralized and collaborative real-time rendering offloading network architecture (CRCDnet) to address this issue. CRCDnet makes contributions in the following three areas: (1) In the user aggregation scenarios, mobile devices that perform the same services are used as service nodes to perform the offloading of rendering computing and a collaborative rendering computing network is established. (2) For data exchange in decentralized networks, a data sharing middle layer based on blockchain key indexes separates sensitive service data and ensures a secure, reliable exchange mechanism and efficient data exchange. (3) A data request and computing offloading scheduling approach is proposed for the collaborative rendering computing network to optimize the rendering computation delay.

Traditional access control models cannot effectively manage authorization for independent and geographically dispersed information. This drives the research interest in more flexible and efficient access control approaches, in particular role-based access control. This report covers both RBAC subfields- theoretical modelling and practical deployment, provides an introduction and overview of role-based access control appropriate for the emerging world of virtual organisations and remote collaboration. We take a specific application area, distributedcollaborative tutoring as pioneered in the MANTCHI project, and show the merits of the RBAC architecture for meeting its security requirements.
