Abstract

Aim: To deploy Cloud Components in a cloud integrated WOBAN in a cost-efficient manner.

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 work.

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.
