A Game Theoretic Approach to Optimize Transmission Strategies for Mobile Applications

In the last years, mobile devices need more and more transmission capacity, despite the development of the number and the performance of network interfaces, these latter cannot be fully utilized by the most applications. In this paper, we propose a solution to the network resource allocation problem under the selfish behavior of mobile applications with multiple connections to a several available network interfaces simultaneously. Where those applications are not only in interaction with others phones applications, but also with applications in the same phone, in particular, those applications which require more data rate speed (voice over internet protocol, the live video streaming, online gaming,). A transmission mobile applications game is proposed to resolve the conflict of interest in the network, under different types of interactions (cooperation/competition). After showing the existence and uniqueness of equilibrium in terms of number of concurrent connections, we analyze the impact of interactions between applications on the data transfer rate. We also validated our theoretical study with numerical results, which show that the non-cooperative game has an equilibrium point which depends on all parameters of the system; and we show that the cooperative situation between applications is much more beneficial in terms of the performance of mobiles and the data transfer rate.
