Simulation of FTTR Network and Radio Resource Scheduling Based on NS-3
In the current optical access network solution,the optical network and wireless network operate independently,lacking a collaborative mechanism,leading to mutual interference between devices.By introducing a centralized decision control mechanism,the master device can make centralized decisions based on information reported by subordinate devices,enabling the collaboration between optical andwireless networks.XG-PON module was added to the NS-3 platform to simulate the FTTR network and establish radio resource scheduling strategy under master device's control.In the simulation the uplink and downlink data transmission and uplink band width allocation functions of the XG-PON module are realized in NS-3,and data transmission schedule for multiple users in the FTTR network is performed.The overall network data throughput is increased by 0.64%to 5.66%under different user quantities,which indicates the centralized decision mechanism is capable of effective scheduling.
