Building energy efficient LR-PON for desert terrain of Saudi Arabia

With the increase of bandwidth demands, an increasing concern prevails among researchers towards energy consumption in next generation access networks. Attempts have been made by researchers with an overview of techniques and architectures for energy consumption minimization in core networks. Growing concern equally exists essentially to reduce Green House Gases (GHG) emissions from computers and network equipments. In the present paper, we focus on renewable energy utilization at access level as well with a view to build energy efficient long range passive optical networks (LR-PON) for desert terrain of Saudi Arabia. In this paper we have presented LR-PON model between Riyadh and Al-Kharj with an admission control algorithm for efficient performance of LR-PON. Also, in this paper we have shown how to reduce network complexities and provide a cost effective solution by greening the network at the access level by using solar energy which is renewable and clean.
