MM3C: Multi-Source Mobile Streaming in Cache-Enabled Content-Centric Networks

Along with an ever-growing demand for rich video applications by a rapidly increasing population of mobile users, it is becoming difficult for the Internet backbone to cope with a constantly increasing mobile traffic. Though multi-source mobile streaming (MS2) was proposed to solve the bottleneck issue of the Internet backbone considering simultaneous multiple low streaming rate transmissions to mobile users, it does not consider redundant transmissions of popular contents. Recently, Content Centric Networking (CCN) is proposed as a content name-oriented approach to disseminate content to edge gateways/routers. In CCN, if the content is popular, the previously queried content can be reused for multiple times to save bandwidth capacity, reduce overall energy consumption, and improve users´ Quality of Experience (QoE). Inheriting all advantages of CCN, a novel architecture "MM3C", which integrates CCN with MS2, is proposed as a better solution to the problem. Using OPNET, the performance of MM3C is evaluated. Compared to MS2 under the same network configuration, the simulation results show that MM3C exhibits less bottleneck links, shorter round trip times, and better performance in terms of traffic offloading.
