Vehicular environments are significantly limited by their connectivity, and physical addressing solutions are unable to cope with the increasing challenge of enabling efficient network access. Information-centric networking is poised as an alternative capable of enabling efficient communication in highly-mobile vehicular environments. In this work, we present a service-based system architecture for...
Information-centric networking is poised as an alternative to the address based network model, being mobility friendly and allowing for improved caching. However, VANETs, one of the biggest trends in ad-hoc networking, are defined by their peculiarities and pose additional challenges to the implementation of caching systems. The volatile nature of VANETs requires the development of specialized solutions,...
Studies in Dynamic Spectrum Access often consider aspects of primary communication in their schemes. However, the primary spectrum access modelling is generally over simplistic. This paper considers a realistic modelling of the primary traffic and list a series of parameters that should be considered during spectrum reuse. By modelling primary and secondary communications, a better understanding of...
The radio spectrum is a finite resource and the current spectrum licensing model has led to a fenomenon known as spectrum scarcity. Several approaches have been presented in order to improve the effectiveness of spectrum utilization. This works main contribution is is to present an approach to opportunistic spectrum sensing and allocation focused on maximizing spectrum usage while minimizing communication...
The current spectrum allocation model aims to avoid interferences in licensed spectrum communications without further concerns regarding spectrum usage. Because the radio spectrum is a finite resource, several approaches have been presented in order to improve the effectiveness of its utilization. The main contribution of this work is to present an opportunistic approach to spectrum sensing and allocation...
