Resource management is a crucial task in vehicular ad hoc networks (VANETs) due to the existence of various resources, such as text, audio and video. However, the highly dynamic network feature and the limited memory of the local server pose challenges to resource management, which not only lead to the failure of resource presentations to users, but the transmission of the invalid fragment data would...
The usage of Road Side Units (RSUs) acting as a buffer point in VANETs alleviates the intermittent vehicle-to-vehicle (V2V) connectivity problem. However, due to the vehicle mobility and the short RSU-transmission-range, a vehicle dwells short time inside an RSU. Nevertheless, quick response from the RSU server, helps a driver to make a quick decision while driving. Network coding is known to be efficient...
Location-based routings for Vehicular Ad-hoc Networks (VANETs) use location information in routing decisions. However, location-based routing protocols need location services to query the location information of the communication partner node so that packets could be forwarded properly. In this paper, we propose a proactive flooding-based location service which name is Semi-Flooding Location Service...
In order to have safe vehicular traffic across the expressway a real-time monitoring has become a vital need for the today's intelligent traffic monitoring systems(ITS). In this paper we present a design and development of low cost and reliable Internet of things framework which consists of an array of RFID sensors for the real time tracking of the vehicle on its transit from one point to other point...
Developing countries like India needs a significant improvement in infrastructure such as Roads or Highways. Construction of these highways is a costly affair, which can't be invested by the government alone. Normally Public private partnerships are made to construct such a huge projects. The money spent on these projects can be regained by collecting toll from the passengers who use the roads. The...
With digital maps of the transport network and realtime traffic updates, today's navigation services provide good quality routes in the major route level. Once entering the last mile near the destination, they unfortunately can be ineffective and, instead, local drivers often have a better understanding of the routes there. Given the deep penetration of 3G/4G mobile networks, drivers are now well...
In VANET the first and foremost requirement for a vehicle is that it should have the freedom to move around from one network region covered by a particular access point to another. Since the vehicle can move around in the system but the Infrastructure is immobile, it becomes mandatory to perform a handover procedure from the previous access point to another so that the vehicle can maintain a continuous...
The structure of passenger counting and public transport tracking system of smart city and structural model based on the method of complex discrete systems simulation Petri nets are developed in the article. Reachability graph of the system states that allows to investigate the dynamics of the system is given. The functioning of the implemented system of passenger traffic and public transport tracking...
In Vehicular Ad-hoc Networks (VANETs), any vehicle uses a location service to get an up-to-date data of all vehicles' positions in its vicinity. Many location services rely on infrastructures to perform location update and location query tasks. However, the infrastructure penetration rate may differ from one region to another. We propose in this paper a new location service called Vehicle-Aided Location...
Carpool commuting enables multiple individual travelers with similar schedules and itineraries to share a common vehicle during a trip, and travelers can split travel costs in gas, parking and tolls with each other. It emerges as an effective way to solve traffic congestion, parking space tension and air pollution resulting from vehicle emissions. One of the challenges that restrict widespread adoption...
The lack of traffic signal intelligibility and insufficient information about road conditions is often cited as an important factor that leads to an increase of road accidents and fatalities. To overcome this problem, a number of systems have been developed in order to signal events to emergency points and designed to supply drivers with information about roads conditions to avoid approaching risks...
Serious disasters have been annually occurred in Japan. Particularly, in the Great East Japan Earthquake that occurred on March 11, 2011, the communication infrastructure was seriously damaged over wide areas. Due to such situation, more resilient network infrastructure that does not stop under challenged communication environment is required. In this paper, we propose a disaster information system...
Aeronautical Mobile Airport Communications System (AeroMACS) is being standardized in order to provide new broadband wireless communications on airport surface. AeroMACS will be used for voice-based Air Traffic Control (ATC) services in the future as it is recommended in standards and recommended practices (SARPs) of the International Civil Aviation Organization (ICAO). Therefore, we evaluated the...
Commercially available wearables and apps that convert mobile devices into data collection hubs can be used to implement smart applications in aware cities. In this paper, we consider wearable devices on various human users as a networked cluster of computing power and information source in an Internet-of-People architecture. Applications can be developed to perform computation on this data and gain...
With the constant increase in vehicular traffic, existing traffic management solutions have become inefficient. Urbanization has led to an increase in traffic jams and accidents in major cities. In order to accommodate the growing needs of transport systems today, there is a need for an Intelligent Transport System. Vehicular Adhoc Network (VANET) is a growing technology that assists in Intelligent...
We present cooperative moving object tracking with multiple mobile sensor nodes, each equipped with a multilayer laser scanner. Moving objects in the laser-scanned images are detected by a binarized occupancy grid method. The sensor nodes send the information of the detected moving objects to a central server, which estimates the size, position, and velocity of those objects using a Bayesian filter...
The working of the GPS requires a clear line of sight for accurate services. However this is a drawback when the vehicle is stuck in a long tunnel or a place where the GPS data is unavailable. In this paper we propose the TLST: Time of Arrival Based Localization and Smart Tunnels in VANETs. The paper focuses on the time of arrival and time difference of arrival based localization in the vehicular...
In this paper, we propose a smart parking system detecting and finding the parked location of a consumer's vehicle. Using ultrasonic and magnetic sensor, the proposed system detects vehicles in indoor and outdoor parking fields, accurately. Wireless sensor motes support a vehicle location service in parking lots using BLE.
In this paper, we design and implement the visualization tool for the VMS (Variable Message Signs) emulator which can generate the data fields for the variable text message frame and can generate the window controls such as RadioButton, TextBox, ComboBox, and etc automatically in order to input the valid data value for the instances of variable data using the visualization tool. A variable message...
Security protocols built on strong cryptographic algorithms to defeat attempts of pattern analysis are popular nowadays, but these algorithms consume a lot of processor's efficiency. So, devices with limited processor capabilities need some modified protocols. Billions of such devices, known as ‘smart objects’ are used in IOT (Internet of things). IOT is an interconnection of a large number of smart...
