Plagiarism detection is a challenge for linguistic models — most current implemented models use simple occurrence statistics for linguistic items. In this paper we report two experiments related to plagiarism detection where we use a model for distributional semantics and of sentence stylistics to compare sentence by sentence the likelihood of a text being partly plagiarised. The result of the ...

Vehicle-to-Everything communications (V2X) are becoming increasingly popular as a solution for safer roads and better traffic management. One of the essential protocols in V2X is Dedicated Short Range Communication (DSRC) protocol suite. DSRC includes IEEE 802.11p that operates at medium access control (MAC) physical (PHY) layers. Upon collision, MAC layer applies carrier sense multiple access/...

This research report explores the recent 3GPP LTE D2D rel. 14 Radio Resource Management specification to identify the challenges and evaluate the potentials of Unsupervised LTE D2D (mode 2) for Safety-critical V2X Communications. It also proposes two distributed resource allocation strategies for unlicensed band access. Complementary to DSRC/ITS-G5, Unsupervised LTE D2D is an opportunity to pro...

VANETs are a form of mobile ad-hoc networks to provide communications among nearby vehicles and between vehicles and nearby fixed equipment. Safety applications like collision alert merge assistance, road condition warning, etc requires messages to be propagated from the point of occurrence to the target vehicles with very low latency. DSRC is a two-way short-to-medium range wireless communicat...

Vehicular AdHoc Networks or VANETs are emerging as a promising technology for providing safety and comfort applications for vehicular transportation. VANETs are receiving growing attention from the research community and from the transportation industry because of their great potential to improve traffic safety on roads. In existing system the IEEE 802.11 broadcasting mode, considers no request...

In The current scenario, a new protocol standard such as Dedicated short range Communication (DSRC) IEEE802.11p is implemented using with expensive hardware prototypes but still new physical layer and signal processing algorithms are not integrated on it .The DSRC radios for practical experiments are either commercial grade solutions which are developed for field tests, are rather expensive and...

The network simulator ns-2 [1] is a widely used tool in the field of wired and wireless communications research. Although the ns-2 implementation is in constant evolution, it fails, for obvious reasons, to reflect all aspects related to the newest communication technologies. One example of such technology is 5.9 GHz Direct Short Range Communications (DSRC) [2] for vehicular environments, which ...

All automobile manufacturers continue to incorporate more and more technological features into their vehicles. One of the features is wireless access. A Vehicular Ad-Hoc Network or VANET is a technology that uses moving vehicles as nodes in a network to create a mobile network. VANET turns every participating vehicle into a wireless router or node. Some measurement studies have previously been ...
