Dependability of computer and communication networks is an important aspect of the customer-provider relationship in the telecommunication industry. Considering the increasing interest in Software-Defined Networking (SDN) technologies, as well as unclear understanding of dependability in the context of traffic flows in such networks, it is not clear how to define the related objectives in Service...
Software-Defined Networking (SDN) has gained momentum in recent years, in a bid to transform networking ecosystems. It has already been applied to data center networks and wide area networks, such as Google's WAN. A software-defined approach is thus a reasonable candidate architecture for other highly dynamic environments such as future 5G mobile networks. This paper presents a two-level software-defined...
This paper presents a tracking scheme for residual frequency offset (RFO) affecting a digital video broadcasting (DVB-T) system. Comparisons of the algorithm with two previously reported estimators in terms of mean square error (MSE), complexity and convergence are performed. The proposed scheme improves performance and convergence while reduces the computational complexity.
The utility of automatic systems to visually identify vehicles based on the recognition of their license plates is nowadays unquestionable. They can be applied in very different scenarios, like access control, calculation of parking fares, automatic payment of tolls or parking fines, traffic control, etc. In the literature numerous works can be found proposing solutions to the automatic license plate...
