In vehicular ad hoc networks (VANETs), beaconing (i.e. periodic transmissions of beacons) is one of the most challenging issues, which is mainly used to advertise the presence of a car to its neighbor cars. Based on the proximity awareness achieved ...

Given the limited resources and computational power of current embedded sensor devices, memory protection is difficult to achieve and generally unavailable. Hence, the software run-time buffer overflow that is used by the worm attacks in the Internet ...

This paper presents a new energy-harvesting provider for ns-3 simulation tool. The provider model assumes solar energy harvesting and super-capacitor storage to supply power to a Wireless Sensor Node. Super-capacitors charge and discharge is dynamically ...

The quality of the communication links in a Wireless Sensor Network often shows significant asymmetry and variation over time, due to, for example, heterogeneous settings of the transmission power, moving nodes or changing external interference. This ...

This work presents the modeling methodology of the iTETRIS platform to integrate and simulate ITS applications. iTETRIS is a modular and open-source simulation platform composed of four key modules: the network simulator ns-3, the traffic simulator SUMO,...

We consider the challenging problem of distributed tracking using wireless sensor networks (WSN). In our scenario, multiple spatially distributed sensor nodes estimate a physical process (viz. a moving object) and transmit quantized state estimates to a ...

This work addresses synchronization in multi-hop wireless access networks, with the main but not exclusive purpose of providing end-to-end Quality of Service by time-based scheduling. In these networks all nodes require a common notion of time in order ...

Wireless local area networks (WLAN) are common in universities and their popularity grows every day. Understanding the trends in the use of these networks (i.e. how much, when and where traffic is present) is becoming more relevant. Interesting results ...

In this paper we study a novel distributed rendezvous protocol for cognitive radio networks (CRNs), which is based on a grid quorum system, hence we call it the gQ-RDV protocol. A paper tackles with an asymmetric channel view problem rarely investigated ...

In this paper, we explore the possibility of deploying a cognitive network that can opportunistically access the spectrum allocated to a primary cellular network. The main problem is that cellular networks are characterized by multiple simultaneous and ...

We study the effect of deployment of low cost, low power micro base stations along with macro base stations on energy consumption and capacity of downlink LTE. [1] studied this problem, using spectral area efficiency as the performance metric. We show ...

Wireless networks are usually modeled as spatial objects, and more specifically with random processes generating the locations of individual nodes. This is in stark contrast to the fixed networks case, in which graph models are typically used. While ...

We address the problem of finding efficient combinations of transmitting links between nodes distributed as a spatial Poisson process in an infinite plane using a stochastic optimization method called simulated annealing. A simple Boolean interference ...

The OpenAirInterface emulation platform is an integrated tool allowing large-scale networking experimentation applicable to both evolving cellular and adhoc/mesh topologies. The platform in built to represent a realistic system in a controlled and real-...

Today, network operators are facing the new era of home networks where wireless 5 GHz band begins to play an important role. With higher capacity of standards operating on this band (e.g. IEEE 802.11a/n/ac), quality of service can be improved ...

In this paper we investigate the influence of the codecs into the energy consumption of VoIP applications. These applications are increasingly extended among users of battery- dependent devices such as laptops, smartphones and tablets. We provide a ...
