A Techno-Economic Model of Sustainable Communication Infrastructure in the Smart City; using WDM-PON FTTx

ICT development has caused evolution in service delivery methods. With the increase in population density in urban areas, it is necessary to change and develop the infrastructures. Fiber optic network is a  sustainable communication platform in the smart city and supports all broadband and narrowband services. In this paper, the role of fiber optics in the smart home (with broadband capability) and mobile network (5G) are considered as the two main parts of a smart city. A techno-economic model of  communication infrastructure in the smart city (using multi-purpose fiber optic network with existing  resources consideration) is stated by mixed integer linear programming (MILP) method. In this literature, whilst providing fundamental communication in the smart city, decreasing the vulnerability to threats and increasing the percentage of security and reliability, technical requirements are met and the Capital Expenditure (CAPEX) of network is reduced, as well.
