Aim: To deploy Cloud Components in a cloud integrated WOBAN in a cost-efficient
Background: Wireless-Optical Broadband Access Network (WOBAN) is a network which provides
higher bandwidth and better stability at lower cost to the users. Integration of cloud services over traditional
WOBAN called as CIW (cloud integrated WOBAN) increases existing load carrying capacity
and available bandwidth. In CIW, Cloud Components (CCs) are integrated as storage components,
servers etc. within WMN of WOBAN. These cloud components may follow distributed or centralized
architectures. Availability of these low-cost and easy-to-deploy CCs make CIW technologically
feasible and practically deployable architecture.
Objective: The proposed algorithm eliminates redundant ONUs and optimizes number of CCs while
ensuring network connectivity and cloud services to all users.
Methods: Extensive simulation is carried out to implement proposed work. A simulation model and
code is developed in MATLAB to get the results for existing and proposed algorithms for varying
number of variables such as number of ONUs, wireless routers, grid sizes etc.
Result: We compare the performance of proposed algorithm with existing algorithm for varying grid
sizes as well as number of wireless routers. Simulation results show the worthiness of proposed
Conclusion: Optimization of cloud components in CIW is one of the important issues as it affects
overall network deployment cost. Considering this issue, we proposed a cluster based approach to
optimize number of network components such as CCs and ONUs in the network. Simulation results
show that cluster based approach is efficient as compared to existing approach for optimizing CCs.
Hence proposed solution offers a suitable candidature for deploying a cost efficient CIW.
