In recent years a great attention has been captured by the researchers in 5G networks merging of radio frequency and optical fiber technologies known as Radio-over-Fiber (RoF) system which can provide cost-effective, and high-capacity wireless access network provisioning of broadband, interactive, and multimedia wireless services. It is a promising challenge to improve the network coverage and balancing the load of network resources specially in terms of densed wireless access network. This paper reviewed the existing works focusing on load balancing techniques both explicitly and implicitly for wireless network using RoF technology. It is noticeable that all the researchers have focused on different types of static and dynamic load balancing schemes based on logical resources like bandwidth, frequency, wavelength and physical network resources like number of remote radio heads, base stations and mobile unit or mobile users by using mathematical models, algorithms, reinforcement learning for both radio access network and could or software defined network using RoF technologies. All these works are evaluated for different parameters like bandwidth, latency, frequency, wavelength, delay, time, interference, and number of mobile units. But still there is scope for future work to focus on effective, efficient, scalable, dynamic, cost effective and also energy efficient load balancing mechanism for dense wireless access network using RoF for ensuring quality of service to the large growing population.
