Next Generation Networks (NGN) are based on the coexistence of heterogeneous systems delivering diverse services and assuring high data rates. Small cell systems (Pico-cells and femto-cells) based on Radio over Fiber (RoF) networks are a booming technology since they densify the network, burst the network capacities and increase the system throughputs. This(More)
Providing high data rates and wide bandwidth applications are the most important challenges that mobile systems and radio networks are trying to accomplish. Radio over Fiber-RoF systems is a promoting research field since it benefits of Passive Optical Network (PON) advantages and unlicensed large bands in 60 GHz millimeter band (57-64GHz). In this study,(More)
Next generation Optical Networks become a topical issue that requires much researcher's interest especially the improvement of last miles of the optical networks (access network). Radio over fiber technology fulfills with heterodyne optical networks needs since it answers to wideband applications requirements and meets high capacities networks. The(More)
In this paper a novel cognitive Radio over Fiber (RoF) system lined up with Software Defined Networking (SDN) requirements is presented. First, the SDN paradigm for the proposed hybrid RoF system with centralized topology is developed. Then, cognitive process enabling self-aware RoF network is outlined. The goal is to allow traffic and network supervision(More)
The development of reconfigurable and high throughput architectures is the utmost target for researchers in the field of Radio over Fiber (RoF). In this paper, we developed a cognitive radio over fiber system lined up with Software Defined Networking owing to improve the quality of transport using a pre-equalization technique. The pre-equalization technique(More)
