TLDR
Experimental results indicate that the proposed mechanism improves system performance by allocating resources according to service priority and the proposed architecture also significantly improves system capacity to accommodate numerous users.Abstract:
A novel IP Multimedia Subsystem (IMS) framework with cloud computing architecture is proposed for use in high-quality multimedia applications. The IMS supports heterogeneous networking with Quality-of-Service (QoS) policy. MapReduce analysis is also used to enhance cloud computing capability. This architecture enables users to access high-quality multimedia applications via Android-based appliances. In this study, the IMS QoS policies of three wireless access technologies, 3G, WiFi and WiMAX, are integrated in a cloud computing environment to provide different services such as VoIP services and video streaming services. Experimental results indicate that the proposed mechanism improves system performance by allocating resources according to service priority. The proposed architecture also significantly improves system capacity to accommodate numerous users.read more
