Bahar: A new hybrid of GA and auction method for dynamic bandwidth allocation based on EPON networks

One of the major challenges in the Ethernet Passive Optical Networks (EPON) technology in providing quality of service for the network users is the optimum and dynamic allocation of bandwidth that has been requested by the users. In this paper, a hybrid method is proposed that is based on the genetic algorithm and the auction theory where the requested bandwidth is calculated precisely with the genetic algorithm and subsequently the bandwidth is allocated through an auction process. For performance evaluation, the proposed Bahar method was compared with IPACT and FSD-SLA bandwidth allocation methods. Simulation results show that Bahar in comparison with IPACT and FSDSLA (Failure Sensibility Degree-Service Level Agreement) experiences more delay but regarding other quality of service parameters such as packet loss ratio, line utilization, and throughput, it has better performance.
