Cognitive mesh networks (CMNs) are presented as a future solution for the near spectrum crunch. The spectrum availability is analyzed as the main barrier against the success of CMNs and huge data transmissions using cognitive communications. The cognitive radio-over-fiber (CRoF) subnet here is proposed as a solution for small enterprise microcells services in CMNs. The CRoF architecture is based on using the radio over fiber (RoF) to connect cognitive radios (CRs). These CRoF stations are positioned inside the primary macrocell coverage area and in coexistence with the primary base stations (BSs). Accordingly, CRoF would be able to use local spectrum holes efficiently and provide higher throughput to secondary users. The contribution Digital propose the possible CRoF management scenarios and to evaluate the suggested systems’ performance. Opnet simulations show key savings in time delay and throughput increase using the CRoF subnet, compared with the traditional CR functioning.
