Vehicular network is regarded as an important part of the Intelligent Transportation System (ITS). However, with the increasing number of vehicular applications, it is a challenge to meet the demands of both communication and computation. Fog computing can provide mobile users with the demanded services through low latency and short-distance local connections. This paper investigates the optimal deployment...
In this paper, based on an in-depth analysis of Geographical Routing Protocol (GRP), especially its next hop selection, we present an improvement for the strategy of next hop selection with a joint consideration of distance factor and hierarchical quadrant. Based on the next hop selection strategy, an Improved Geographic Routing Protocol (IGRP) has also been proposed in this paper, which has a higher...
Information security in FPGAs is at risk; during system operation, data and usage patterns can potentially get imprinted into a chip's physical characteristics, allowing an attacker to later recover intellectual property or cryptographic secrets. Can “data burn-in” vulnerabilities in FPGAs be characterized at low cost? Specifically, can slight shifts in path delays due to burn-in be measured with...
