The focus in research relating to peer-to-peer (P2P) networks and possible configuration schemes for efficient cloud-based video streaming services in mobile devices has seen a substantial growth as the number of mobile devices increases. There have been various P2P configuration schemes proposed for high quality multimedia streaming, but for the most part these have been for wired networks. However, the two prevailing scheme configurations for wireless networks are the ad hoc on-demand distance vector (AODV) scheme and the optimized routing independent overlay network (ORION) scheme.

The authors propose a new configuration scheme that would be more resilient in streaming video to multiple devices. This scheme is called connectivity-aware mobile P2P (CAMP). It consists of a group of mobile devices configured to form a sharing tree. This sharing tree comprises a primary group leader (PGL), a secondary group leader (SGL), parent nodes, and child nodes. The PGL device is responsible for managing the group; it receives the cloud-based service video and transmits it to all other devices. The SGL works as a backup to the PGL in case the connection is lost from the sharing group. The authors provide an algorithm that the PGL would use to determine the size of a sharing group and the logic to manage the parent and child nodes.

The CAMP network that the authors propose is tested along with the AODV scheme and a non-P2P scheme that directly downloads content into individual devices. The tests that the researchers conduct are on server traffic for various numbers of mobile devices, video disconnection times while a certain percentage of mobile devices are disconnected, and the maximum number of mobile devices that are supported for each scheme. The CAMP scheme outperforms the other two schemes in all of the tests, and the data shows that the authors’ proposed scheme is better than any of the other network schemes.
