The management of distributed software defined networks in smart cities

The emergence of smart city concept increases the needs for updating the abilities of the traditional network (Loffreda, 2015). The network of smart cities requires updating its topology and services dynamically using management software to automate this operation. In addition, it needs to run multiple logical networks over a single network infrastructure similarly to the data centres nowadays. The automation of dynamic behaviour achieves using a novel paradigm of the network that contains a forwarding devices have a central management, called Software-Define Network (SDN). SDN provides faster, cheaper and more efficient network. In addition, it strongly supports Network Function Virtualization (NFV), which enables executing the network functions using the software component instead of physical devices (Foundation, 2015). Therefore, NFV enables to run multiple logical networks on the single physical network. Moreover, it enables faster deployment of new services or updates the old ones. The aim of the research is to develop a management algorithm automates the dynamical adaptation for network topology in smart cities
