Load balancing model based on Stackelberg game for multi-homing in heterogeneous radio access networks

Abstract

We address the problem of load balancing for multi-homing in heterogeneous radio access networks, where multiple wireless access networks compete with each other to offer bandwidth. We firstly have presented a Stackelberg game-theoretic model for dynamic load balancing in heterogeneous radio access networks. We have formulated this situation as an oligopoly market in which the multi-access networks adjust their prices dynamically to gain the maximize profit. A linear incentive mechanism and a non-linear incentive mechanism were proposed to the load balancing problem, by Stackelberg game model we can make the network bandwidth to be rationally and effectively used. Simulation results show our model to enables radio access network to maximize their revenue, and ensure efficient use of bandwidth to achieve load balancing.
