摘要

摘要: 光無線混合網絡的生存性保障程度與部署成本之間存在矛盾。為提高網絡資源利用率，該文提出一種低成本的無線功能部署策略。根據網絡中無線功能部署情況，綜合考慮網絡生存性保障程度及部署成本兩方面因素，在此基礎上，提出基于向量評價的二進制粒子群算法實現其優(yōu)化過程，進而，由進化得到的種群粒子不斷調整光網絡單元選取，以較低的成本實現較強生存性的網絡部署。結果表明所提出的無線功能部署策略能有效提高網絡的生存性，并大幅度的降低網絡成本。

Abstract: There is a contradiction between the degree of survivability and the cost of deployment in Hybrid Optical-Wireless Broadband Access Networks (HOWBAN). To improve the network resources utilization, a low- cost Optical Network Unit (ONU) deployment strategy is proposed. According to the deployment of wireless functions in the network, the degree of network survivability and the deployment are considered in the optimization process of vector evaluated binary particle swarm optimization. Furthermore, to deploy the network with low cost while at the same time guaranteeing a high degree of survivability, the selecting of optical-network-units can be decided dynamically by the evolution of particle. The results show that low-cost ONU deployment strategy can effectively improve the network survivability, and reduce network cost.
