Joint subcarrier channel and time slots allocation algorithm in OFDMA passive optical networks
چکیده انگلیسی

This paper investigates upstream resource allocation problem in Orthogonal Frequency Division Multiplexing Access Passive Optical Networks (OFDMA-PON). One assignment problem with subcarrier channel utilization and Total Grant Time (TGT) is analyzed and formulated. The Shortest Request First Scheduling (SRF) algorithm and Greedy Scheduling Algorithm (GSA) are demonstrated and evaluated through simulations. The results show that the proposed algorithms achieve less TGT and higher channel utilization compared with traditional sequence scheme.
