The development of unmanned vehicle technology is rapidly proceeding and will result in numerous advances in autonomous vehicles. Most of the research effort to date focuses on the safe and effective operation of these vehicles that will allow them to integrate into society. A research gap exists though in the technical, policy, and legal fields re...

In military doctrine, key terrain refers to areas which, if seized, afford an advantage to an attacker or defender. When applied to geographic terrain, this definition is clear. Key terrain might include a hill that overlooks a valley an enemy wants to control or a crossing point over a river that must be traversed before launching an attack. By de...

Summer immersive experiences provide students the opportunity to explore the limits of their engineering education and develop a depth in a field of study. For institutions that centrally manage these experiences, ranging from experiments conducted at other academic locations to research and development with industry partners, to procurement and de...

Vehicular networks are meant to exist wherever the road will take them. This includes small towns, rural highways, suburbs, downtown urban centers, and urban highways. The density of vehicles varies greatly across these environments. This work looks at the effects of implementing Quality of Service (QoS) as well as a relatively similar method that...

As vehicular networks (a.k.a. VANETs) continue to mature, the benefits they promise come closer to reality. For this to happen, both security and privacy must be provided. Particularly in dense urban environments, novel methods of distributing the often changing identity (pseudonyms or PNs) of the vehicles is necessary in order to ensure vehicles h...

Vehicular Networks (VANETs) continue to mature and their installation is becoming a reality. Meanwhile, simulation has become an indispensable tool for validating design and providing insight into how complex systems work. Yet the results of a simulation are only as good as the simulator's configuration. The network simulator 3 (ns-3) provides a ho...

In this paper, the primary objective is to discuss the details of scalable methods for distributing certificate revocation lists and other large files using vehicle-to-vehicle and vehicle-to-infrastructure communications while taking advantage of the multi-channel operations in IEEE 1609.4. We also discuss the results from a simulation study using...

Vehicular ad hoc networks (VANETs) provide the means to add convenience, services, and safety to the road. This paper introduces a means to adapt the concepts of Public Key Infrastructure for a VANET environment under the worst case scenario of a pseudonym shift every second. Regions are used to scale down the size of certificate revocation lists (...

VANETs continue to mature and their installation is becoming a reality. Many ideas have been exchanged on how best to balance privacy and security. The use of pseudonyms has been almost universally accepted as a critical part of this equation. Simulated results, using ns-3, demonstrate the need for more than a single road side unit (RSU) contact fo...

Concerns for VANET participants will be the reliability and trustworthiness of received messages and the privacy in the use of the VANET to prevent vehicle tracking. To address these concerns, public key certificates have been standardized for VANETS; however, with the use of public key certificates comes additional concerns, especially how to ensu...

This paper describes a novel idea for distributing certificate revocation lists (CRLs) in a vehicular ad hoc network (VANET) scenario. The idea, Most Pieces Broadcast (MPB), takes advantage of the two distinct channel types in VANETs while reducing contention for the wireless medium. Broadcast methods that reduce wireless medium contention in VANET...

The objective of this research is to investigate improved methods for distributing certificate revocation lists (CRLs) in vehicular ad hoc networks (VANETs). VANETs are a subset of mobile ad hoc networks composed of network-equipped vehicles and infrastructure points, which will allow vehicles to communicate with other vehicles and with roadside in...

This paper discusses two new methods for distributing certificate revocation lists (CRL) in a vehicular ad hoc network environment using cooperative methods. The main purpose for using cooperative methods is to attempt to reduce the number of collisions in the dedicated short range communication (DSRC) broadcast environment. The reduced number of c...

Each June approximately 1200 new cadets (NCs) are welcomed to the United States Military Academy (USMA) during Reception Day (R-Day). Amid the mass shuffling of bodies and the yelling of the upper-class cadet cadre, all 1200 NCs must process completely. Changes are made to the in processing system in attempt to make it more efficient. However, the...
