ABSTRACT: Dealing with data transmission in smart grid networks is one of the most challenging topics in telecommunications industry. Wireless mesh network (WMN) and Power line communication (PLC) are suitable technology for distributed smart grid communication; both connections are lossy connections. Network virtualization (NV) is a promising innovation to bolster customized end-to-end execution of different services in real-time. In this paper, a NV-based structure is proposed for smart grid communication, where real-time services are upheld by virtual networks that are mapped to both physical systems at the same time. Since the VN mapping and subcarrier task issue is nondeterministic polynomial-time hard, heuristic solutions are implemented. To reduce the complexity of the system, data sparsification algorithm is applied to the input of the system. The results with the data sparsification and the results without the data sparsification are compared in the proposed work. Simulation results show the adequacy of our proposed technique.

KEYWORDS: network virtualization, OFDMA-based wireless mesh network, power line communication, smart grid, data sparsification
