Abstract: Some emerging services such as augmented/virtual reality need high data rates. Whereas, the existing 2nd Generation (2G), the 3rd Generation (3G) and the 4th Generation (4G) networks cannot provide such high transmission rates. To meet these requirements, in this paper, the technology and the realization of a “virtual super terminal” that can perform the concurrent streaming of video via the cooperation of multiple heterogeneous terminals are introduced. This paper uses concurrent streaming scheduling algorithm, buffer overhead and packet delivery method, and packet loss prevention and recovery method to improve the performances of the system. Testbed measurements show that compared with the scheme without cooperative transmission this new design can significantly increase system throughput and decrease packet delay.
