Abstract

This paper presents a cooperative video transmission mechanism based on game theory for heterogeneous devices during broadcasting. Broadcasting is a multipoint delivery of transmission that sends data from a source to multiple destinations. The terminal is involved in cooperative transmission when the station broadcast video data. To enhance performance, the heterogeneity and forwarding capabilities should be considered. This work studies power control and allocation in a collaborative transmission based on game theory, which provides an effective strategy when network resources are limited. First, a novel power allocation model of the base station (BS) based on non-cooperative game theory and bidding is presented in this study. Additionally, we also propose the utility function of Signal-to-Noise Ratios (SNRs) along with Signal-to-Interference Ratio (SIRs). Subsequently, based on such non-cooperative game theory with a utility function, the model of the power distribution of terminal in cooperative transmission can be built. Experiments have proven the correctness of the designed model and superiority, verifying the effectiveness of the proposed power-control idea.
