In this paper, we present an analytical model to find the probability density function (PDF) of link life time in vehicular ad hoc networks (VANETs). Assuming free flow traffic state and the vehicle speed to be a random variable with uniform distribution, we analyse the impact of vehicle mobility, vehicle density and transmission range on the link duration(More)
Real-time video processing is a rapidly evolving field with growing applications in science and engineering. Portable video processing systems require design which reduces the power, memory usage, and resource utilization while maintaining real-time operation. General system architecture for real-time video filtering and overlay character generation, based(More)
In this paper, we present an algorithm to predict the residual link lifetime in vehicular ad hoc networks (VANETs) by making use of Kalman filter based prediction technique. Assuming Gauss-Markov mobility model for the vehicles, the algorithm initially finds the relative location coordinates and velocity of the vehicles and using this information, the(More)
The ordinary border patrol system suffers from intensive human involvement. Recently unmanned border patrol system consist of high tech devices, like unmanned aerial vehicles, unattended ground sensors, and surveillance towers equipped with wireless camera. However, any single technique encounters inextricable problems, such as high false alarm rate and(More)
In this paper, we present an analytical model to find the probability density function of link life time in vehicular ad hoc networks, assuming Rayleigh fading channel conditions and vehicle speed to follow uniform probability distribution. We then investigate the impact of path loss exponent, transmit power, threshold SNR and velocity on the mean link life(More)
In Vehicular Ad Hoc Networks (VANETs), geographic routing protocols rely on a greedy strategy for hop by hop packet forwarding by selecting vehicle closest to the destination as the next hop forwarding node. However, in a high-mobility network such as VANET, the greedy forwarding strategy may lead to packet transmission failure since it does not consider(More)
With significant advances in wired and wireless technologies and also increased shrinking in the size of VLSI circuits, many devices have become very large because they need to contain several large units. This large number of gates and in turn large number of transistors causes the devices to be more prone to faults. These faults especially in sensitive(More)
