Non-cooperative differential game based load balancing algorithm in Radio-over-Fibre system

Load balancing plays a critical role in a cellular network. As one kind of cellular network, Radio-over-Fibre (RoF) system can provide ubiquitous high data-rate transmissions, which has attracted many attentions, but it also suffer load unbalancing problem. In order to improve the system performance, in this paper, we propose a novel loading balance scheme in RoF system based on differential game theory. The scheme formulates the load allocated to each RAP (Radio Access Point) as a Nash Equilibrium, using noncooperative differential game to obtain the optical load allocation of each RAP. The simulations performed show that the non-cooperative differential game algorithm is applicable and the optimal load solution can be achieved.
