OPTIMAL ALLOCATION OF RADIO RESOURCES IN A HETEROGENEOUS NETWORK SYSTEM

Abstract

The evolution of wireless and mobile networks is growing. An important issue in telecommunications is the best way to allocate radio resources. Thus, the effective implementation of mobile networks like Long-term Evolution (LTE) and wireless networks like Wireless Fidelity goes hand in hand with the growth of telecommunications networks. In this article, to improve the overall allocation of radio resources, a method using dynamic programming is proposed as part of a heterogeneous system of wireless and mobile networks. Knowing that this problem is dynamic, then Bellman’s principle of optimality is used for its resolution. Considering the mobility of users through the 2D Fluid Flow model, better radio resource allocation performance in heterogeneous networks is achieved. The Network Simulator 3 (NS3) was used to test and validate numerically the results of a better allocation of radio resources.
