In the present scenario, increasing bandwidth demand and data-hungry applications require every network to be equipped with cloud services, as a huge amount of storages, processing power and miraculous speed available with it. Cloud integrated Wireless Optical Broadband Access Network (CIW) is one of the suitable choices to fulfil these requirements. CIW can be realized by deploying Cloud Components (CCs) or thin servers either at optical back-end or at wireless front-end of the (Wireless Optical Broadband Access Network) WOBAN. In the present work, we integrate cloud components at wireless front-end of the CIW. Integration of CCs at front-end offloads traffic associated with cloud services from wireless front-end and diverts it towards CCs, which results in a reduction in bandwidth usage of the wireless front-end of WOBAN. We introduce a novel approach known as cluster-based optimization of network components in CIW. The proposed algorithm eliminates redundant Optical Network Units (ONUs) and optimizes a number of CCs while ensuring network connectivity and cloud services to all users. Simulation results validate that the proposed algorithm offers suitable candidature to deploy cost-efficient CIW.
