In Wireless Sensor Networks (WSNs) there are network functions and applications that need to know the localization of a node such as the association of the sensed data with a given position. In general, it may be impossible or unfeasible to have either a planned deployment or a localization hardware. Thus, an important problem in wireless sensor networks is(More)
This work presents a new hybrid neuro-fuzzy model for automatic learning of actions taken by agents. The main objective of this new model is to provide an agent with intelligence, making it capable, by interacting with its environment, to acquire and retain knowledge for reasoning (infer an action). This new model, named reinforcement learning hierarchical(More)
The Brazilian symposium on computer networks and distributed systems (SBRC) reached its 30th edition as the paramount scientific event in the area of computer networks and distributed systems in Brazil. Faced with this opportune moment in the event’s history, we here study the collaboration network established among authors who have jointly published in the(More)
In this paper we present a case study in the industry about the application of a test case generation method based on B machine specifications. First we describe the step-by-step process of the test case generation method and then we present its use in a particular case study for door controlling module from a subway system. Lastly, we discuss the results(More)
The topological design of a network is a key challenge in order to supply a large set of requirements from telecommunication services required by customers, which include bandwidth capacity, fault tolerance, low levels of delay, security, among others. The fulfilment of such requirements will directly impact on quality of service and customer satisfaction.(More)
Intelligent Transportation Systems (ITS) demand sophisticated vehicular networks integrating entities from the transportation sector. The ability to plan and manage such networks represents a key challenge for moving ITS solutions from laboratories into the streets. In this work, we propose Gamma Deployment as a metric for evaluating the distribution of(More)
Network virtualization is considered a key technique for the future internet, working as an alternative for the "internet ossification" problem. Virtualization technology is considered a new paradigm of networks, allowing multiple virtual networks to co-exist in a common physical substrate independently. In this context, the Virtual Network Embedding(More)
