摘要

摘要: 光和无线(Fiber-Wireless, FiWi)混合网络可以有效解决随时随地接受高速业务的网络接入问题。作为FiWi网络的关键节点，ONU数目和位置很大程度上决定了网络的成本和性能。为降低FiWi网络的建设成本，提升网络性能，该文基于EPON-WIMAX混合组网的FiWi网络，提出一种ONU部署策略，基于改进的遗传算法优化ONU部署，在使ONU数量最少的基础上，保证一定程度上的负载均衡。仿真结果表明该文算法能够避免过早收敛导致的局部最优，得到全局最优、数目最少的ONU部署方案，并实现较好的负载均衡。

Abstract: Fiber-Wireless (FiWi) hybrid network can effectively solve the problem that people need to receive high speed service anytime and anywhere. As the key node of the FiWi network, the number and location of ONUs determine the cost and performance of the network to a great extent. In order to reduce the construction cost of FiWi network and improve network performance, an ONU deployment strategy based on improved genetic algorithm is proposed in the EPON-WIMAX hybrid network. It can minimum the number of deployed ONUs and take into account the load balancing. The simulation results show that the proposed algorithm avoids sub-optimal trap and the final number of ONU is the least, while maintaining a high load balancing level with better performance.
