Vehicle to grid technologies (V2G) utilize the batteries in electric vehicles (EV) to provide ancillary services to the electric power grid. In order to maintain a 60-hertz frequency in the electric grid, there exists a wholesale market for frequency regulation (FR), a specific type of ancillary service. This paper examines V2G technology for providing FR, while focusing on the effect FR service has...
In this paper, we investigate the performance of HWMP, OLSR and DD protocols in a VANET crossroad scenario. The mobility patterns of vehicles are generated by means of SUMO (Simulation of Urban Mobility) and as communication protocol simulator is used NS3 (Network Simulator 3). For the simulations, we used IEEE 802.11p standard, Two Ray Ground Propagation Loss Model and sent multiple CBR flows over...
We present a model of simple cognitive agents, called “creatures”, and their learning process, a type of “social observational learning”, that is each creature learns from the behaviour of other creatures. The creatures may experience fear and/or desire, and are capable of evaluating if a strategy has been applied successfully and of applying this strategy again with small changes to a similar but...
Multifunction vehicle bus (MVB) which obeyed to IEC 61375-1 standard is implied inside the train vehicle as international standard. The measurement index of MVB network dynamic performance including network efficiency, network utilization and network throughput is put forward in this paper. A simulation model based on matlab\simulink is built to evaluate and analyze MVB network dynamic performance...
Vehicular communication, as a novel fundamental platform for providing wireless access, is drawing more and more attentions in recent years. IEEE 802.11p is a main radio access technology which supports communication for high mobility terminals. Due to the small coverage, road side unit (RSU) is usually deployed coupling with cellular network to achieve seamless mobility. In cellular/802.11p heterogeneous...
In this paper, we investigate the performance of OLSR and AODV protocols in a Manhattan grid scenario when sending triple TCP flow over FTP. We considered data rates of 0.1 Mbps and 1 Mbps. For the simulations, we used SUMO and NS3. We considered IEEE 802.11p standard and TwoRayGroundPropagationLossModel. We use through-put and cwnd as evaluation metrics. The simulation results show that for small...
In this paper, we investigate the performance of OLSR and AODV protocols in a VANET crossroad scenario. The mobility patterns of vehicles are generated by means of CAVENET (Cellular Automaton based Vehicular Network) and as communication protocol simulator, is used NS3(Network Simulator 3). For the simulations, we used IEEE802.11p standard, TwoRayGroundPropagationLossModel and sent multiple CBR flows...
In this paper, we investigate the performance of OLSR and DSDV protocols in a highway VANET scenario. The mobility patterns of vehicles are generated by means of CAVENET (Cellular Automaton based Vehicular Network). As communication protocol simulator, is used NS3 (Network Simulator 3). The simulations are done for four different scenarios based on nodes ID. We use Throughput and Packet Delivery Ratio...
We propose a distributed algorithm for controlling traffic signals. Our algorithm is adapted from backpressure routing, which has been mainly applied to communication and power networks. We formally prove that our algorithm ensures global optimality as it leads to maximum network throughput even though the controller is constructed and implemented in a completely distributed manner. Simulation results...
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 inserts stochastic delays in pseudonym (PN) transmission...
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 have sufficient PNs. In this paper, we examine three...
In an automated container port, after a container is transported into the container yard by a rail mounted gantry, the containers are allocated automatically by stacking terminals. A direct stacking mode is put forward in this article to improve the stacking schedule. It is induced to decrease the vertical transportation distance. In fact, the simulation results show that the total transportation...
Intelligent Transportation Systems (ITS) have been under development since the 80's as part of a global strategy for solving many of our modern life transportation problems. These systems enable people to reach their destinations in a safe, efficient, and comfortable way. In order to reach that goal, several radio access technologies (RAT) such as UMTS, WiFi, WiMAX and 5.9 GHz have been proposed for...
This paper proposes new MAC layer based back-off and retransmission strategies for throughput enhancement, in broadcast transmissions of inter vehicular communication. We present adaptive back off strategy which is based on the concept that there exists an optimum contention window (CW) period in a broadcast CSMA/CA system, given the fixed number of users. We also propose a simple probabilistic approach...
Vehicular ad hoc networks (VANETs) are an important example of mobile ad hoc networks (MANETs) because they can save lives by improving safety on our road networks. They are difficult to design however due their inherent characteristics e.g., quickly changing topology, node density and relative speeds of vehicles. These characteristics also make current wireless media access control (MAC) protocols...
Inter-vehicle communications (IVC) based on mobile ad hoc networks have attracted increasing attention of researchers recently. In this paper, we study the communication performance of IVC networks in multilane dynamic traffic streams. We are concerned with the influence of several traffic factors on multilane communications, such as vehicles' high mobility, traffic directions or relative speed, and...
Outbound logistics usually involve the management of truck activities from guiding the trucks into the plant, assigning parking area for waiting and scheduling trucks for loading. However, some problems exist in the current FIFO (first in, first out) loading scheme. It is because when trucks arrive at the loading bay for loading, some products have not been finished with some percent still on the...
