摘要

摘要: 光和無線(Fiber-Wireless, FiWi)混合網(wǎng)絡可以有效解決隨時隨地接受高速業(yè)務的網(wǎng)絡接入問題。作為FiWi網(wǎng)絡的關鍵節(jié)點，ONU數(shù)目和位置很大程度上決定了網(wǎng)絡的成本和性能。為降低FiWi網(wǎng)絡的建設成本，提升網(wǎng)絡性能，該文基于EPON-WIMAX混合組網(wǎng)的FiWi網(wǎng)絡，提出一種ONU部署策略，基于改進的遺傳算法優(yōu)化ONU部署，在使ONU數(shù)量最少的基礎上，保證一定程度上的負載均衡。仿真結(jié)果表明該文算法能夠避免過早收斂導致的局部最優(yōu)，得到全局最優(yōu)、數(shù)目最少的ONU部署方案，并實現(xiàn)較好的負載均衡。

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.
