Abstract :
In this paper we cover the problem of load balancing in terms of optimum cell selection and wireless channel condition in the hybrid optical wireless network. For a given set of multimedia users with minimum quality of service requirements and a set of best effort users we find the optimum resource allocation that guarantees services for the users and maximizes the total network utility. Our model applies for the convergence network of EPON and WiMAX where the TDM-like resource assignment scheme and the WiMAX air interfaces are used. We achieve convexity of the problem and solve the optimization problem. The proposed algorithm is simulated using MATLAB and the results show validation of the framework, i.e., load balancing scheme gains better network performances.
