Resumo:Due to the heterogeneous amount of Internet of Things (IoT) applications, different scenarios for the realization of an IoT network have been proposed, though usually they are incompatible among them. Moreover, the heterogeneity of the applications sets different requirements in terms of networking resources such as low delay in emergency applications or dynamic bandwidth allocation in video surveillance. Another challenge of IoT in smart cities arises from the efficient transport of the gathered information from the source nodes up to the processing and storage centres. Namely, the future IoT will connect to the Internet billions of heterogeneous smart devices with the capacity of interacting with the environment. Therefore, the proposed solutions from an IoT networking perspective must take into account the scalability of IoT nodes as well as the operational cost of deploying the networking infrastructure. This will generate a huge volume of data, which poses a tremendous challenge both from the transport, and processing of information point of view. Moreover, security issues appear, due to the fact that untrusted IoT devices are interconnected towards the aggregation networks. In this master thesis, Improving IoT with Software Defined Networking (SDN), SDN is the key enabler to address security challenges posed by IoT in the context networking. SDN is a new networking paradigm aiming to overcome the limitations of traditional IP networks, which are complex and hard to manage in terms of network configuration and reconfiguration due to faults and changes. The idea is to separate the control plane from the data plane, thereby the control logic in routers and switches will be moved to a centralized network controller. That is SDN, can be viewed as a network operating system which interacts with the data plane and the network applications by means of APIs. Therefore, SDN addresses properly the IoT challenges. SDN allows the enforcement of network security at the edge, and this project will benefit from this approach.
