Secure and QoS-aware communications for smart home services

In this paper, we present the combination of two concepts addressing important aspects for smart home services: a new quality of service concept and a new integrated concept for a smart home security system. We assume that every flat in a house has its own smart device to perform local services and act as an interface for the different sensors and actors inside the flat. These smart computers are interconnected using a plain switched Ethernet infrastructure. All different types of sensors and actors communicate via different types of standards. Based on the classification of each service, we present a solution to prevent congestion situations inside the network. This scheme is not only applicable to the presented scenario, it could also be applied to handle similar problems within classical computer networks and many other fields. These advantages are realized within the affirmation of security of the whole system. All communication channels, all information and user-data and all kinds of access to the system are secured by a comprehensive security architecture.
