Call Admission Control for Interactive Multimedia in 5G Networks

Abstract

Emerging interactive multimedia applications such as VR have some key requirements that communication medium must full fill in order to have a smooth experience. These requirements include higher uplink and down throughput requirement, low latency, and consistent throughput even at the cell edge. Present day 5G Network faces a lack of resource availability for highly sophisticated applications like interactive multimedia. This work proposes a call admission control scheme so that the overall necessary resource allocation for interactive multimedia and noninteractive applications can occur. The scheme uses mobile agents to gather the resource requirement of the applications from the various servers on various customer sites periodically and use this information to selectively offloading of non interactive traffic to alternate available links whenever such a link is available meet interactive applications traffic requirements. The developed scheme has been tested with different sizes of the 5G networks with several virtual reality users along with other background loads of applications. Results are quite encouraging and the system is practically implementable.
