The potential design challenges from the new conceptual car are studied; an actual simulation overcoming part of these difficulties is reported. Section I is the introduction of the ecosystem, section II is the briefing for the customized...
This paper proposes roadway electrification to facilitate wireless charging to accomplish two purposes. The system allows electric vehicles (EVs) traveling on an electrified lane to receive a charge update. It also permits charging of a low-profile autonomous emergency assist vehicle. Several vehicles of this type would be stationed along a congested roadway allowing an automated and quick response...
Recent studies about climate change are mandating a drastic reduction of green house gas (GHG) emissions. Solutions include the utilization of renewable energy sources (e.g., wind, solar energy) and the increased utilization of hybrid and electric vehicles (EVs). In this scenario ICT can play a significant role by fostering the smart utilization of current energy and transportation infrastructures...
Recently, IEEE 802.11p based vehicular communication has been widely studied in different area of vehicular applications. In this paper, we mainly focus on the automated guided vehicle (AGV) applications which have a strict communication requirement for very low transmission delay and very high reliability. However, CSMA-based 802.11p standard has problems with unbounded channel access delay and multiple...
The widespread use of automobiles has resulted in a correspondingly high number of car accidents, and this number shows no sign of any significant decline. Many accidents occur at poor-visibility intersections. To avoid such incidents, an inter-vehicle communication (JVC) system has been proposed [l]-[7]. In Japan, with the changeover in terrestrial broadcasting from analog to digital broadcasting,...
The topic of this paper focuses on the development of formation controller for multiple car-like mobile robots. The studied robot formation is constructed under Leader-Follower approach, so that the follower robots are able to keep constant desired distances and relative bearing angles with respect to the leader. Affected by the data transmission delay between the leader and follower robots, the formation...
By means of recent advancements in the wireless networking area a totally new paradigm came into existence in the domain of wireless communication well known as Vehicular Ad-Hoc Network (VANET) employed specially for providing road safety, comfort and convenience to the driver as well as passengers during their journey. A VANET is a type of highly dynamic wireless network that can be formed without...
Data dissemination is a key component of Infotainment and safety services in Vehicular Ad Hoc Networks. For infotainment services data dissemination starts from a Road Side Unit (RSU) and propagates to a multiplicity of On Board Units (OBU). A RSU typically can reach with a single hop only a fraction of the interested vehicles. Multi-hop, inter-vehicle communications is necessary to reach vehicles...
In this paper, it is mainly analyzes the significance of cooperation and summarizes the related researches. While, this paper puts forward the aims for some problems of cooperation. Under the director of these aims, this paper constructs a cooperation architecture on the basis of intelligent and cooperative information technique and establishes a series of cooperation models with different objective...
We study the performance issues of a realistic simulation of the German toll system for heavy trucks using a discrete-event system (DES) simulation. The article first introduces the German toll system and the simulation framework developed to analyze the systems' behavior. A number of performance limitations of several commercial and non-commercial DES simulation kernels are described, measured and...
Widespread adoption of unmanned aerial vehicles has led to intense interest in increasing the vehicle-to-operator ratio in unmanned systems. We propose a multiserver queueing structure for the supervisory control of multiple autonomous unmanned vehicles and demonstrate that multiserver queueing can increase the vehicle-to-operator ratio. Analytical results are derived for M/M/c queues with identically...
This paper presents a method to estimate the normal load and the cold-load pickup caused by the recharging of electric vehicle (EV) on the distribution transformers. The Monte Carlo simulation method is used to make the estimate in both conditions. The model can calculate the charging load profile with different numbers of customers and different ratios of battery capacity, chargers and car penetration...
In-vehicle wireless communication (IVC) has lately attracted attention because of offering the passenger amenity such as wireless seat-monitor, hands-free phone, portable navigation system and many other equipments. Therefore many papers have been published on IVC. Considering high speed video transmission and less interference to the outside, the use of unlicensed 60GHz band is preferable relative...
In Vehicular Communication Networks, the nodes move in high speed, the topology changes frequently and the channel quality is not stable, which are considered to be the most important factors leading to the deterioration of TCP performance. In this paper, we first analyze the problems of traditional TCP existed in Vehicular Communication Networks. Subsequently, a four-state transition diagram is given...
In this paper, we explore a novel online packet scheduling model based on vehicular network applications. The model incorporates multiple networks with non-persistent connectivity where we only know which networks are available at the current time. Our goal is to achieve the minimum requirement of vehicular application classes and also maximize the throughput of these classes. NS3 simulations were...
We consider cooperative control of robots involving two different testbed systems in remote locations in different time zones, with communication on the internet. The goal is to have all robots properly follow a leader defined on one of the testbeds, while maintaining non-overlapping positions within each swarm and between swarms, assuming they are superimposed in the same virtual space. A dual-testbed...
Cooperative schemes for critical content distribution over vehicular networks are presented and analyzed. The first scheme is based on unicasting from the base station, whereas the second is based on threshold based multicasting. Long Term Evolution (LTE) is used for long range communications with the base station (BS) and 802.11p is considered for inter-vehicle collaboration on the short range. A...
Fast transmission of event-driven warning messages and energy conservation are primary concerns to design robust Hybrid Sensors and Vehicular Networks (HSVNs). In last few years, several protocols have been proposed to address these issues. However, the tradeoff between energy consumption and latency has not been carefully studied and sometimes it is given higher priority than event detection efficiency...
This paper describes an evaluation of a standardized Probe Data Service (PDS) defined for collecting vehicular probe data via Wireless Access in Vehicular Environments (WAVE) networks operating in the Dedicated Short Range Communications (DSRC) band. Our evaluation is performed by simulating the security and networking functions that support PDS. Our key findings are that in the current design of...
For the bus has serious impact on the intersection running effective, the paper gives a new passenger car equivalent method for the bus according to the bus's time-space characteristics. When the bus arrives and departs the intersection without stopping, the passenger car equivalent is set as the section of highway, when the bus passes the intersection experiencing stop, the passenger car equivalent...
