This paper examines the upcoming world of Wireless Services and Intelligent Vehicle Transportation System (IVTS). Recent advances in powerful and miniature computing, and transceiver technology, is enabling more technology to be placed inside a vehicle. The wireless sensors and transceivers onboard individual cars can communicate with other cars, or with the road. The information collected by individual...
The paper proposes a method to implement Tire Pressure Monitoring System (TPMS) in vehicles. TPMS measures the air pressure inside pneumatic tires of automobiles. The proposed TPMS has an electronic unit that directly screws onto the stem of tire. The unit includes a pressure sensor and switch, signal conditioning unit, microcontroller, RF transmitter and long life battery. An onboard RF receiver...
In this paper, we investigate the performance of a single-relay assisted cooperative vehicular network in a highway traffic scenario. Source and relaying vehicles are assumed to be traveling in the same direction with similar speeds. This results in a relative velocity nearly equal to zero and leads to a frequency-flat and time-flat fading in source-to-relay link. On the other hand, source-to-destination...
Electric vehicles (EVs) are clean due to their zero local emissions and low global emissions. They are also green due to their environmental friendliness, since electricity can be generated by renewable sources. Despite these obvious benefits, EVs have not been widely used around the world; the key reasons are due to their high price, short driving range or lack of charging facilities. With the growing...
The time-constrained shortest path problem is an important generalization of the shortest path problem. The basic feature in time-constrained shortest path problem is considering when a node in the network can be visited under some time constraints. In this paper, a label-setting shortest path algorithm will be proposed to use in the synchronized traffic-light networks which uses the waiting times...
Localization using satellite-based GPS is not available in underground mines, therefore a new approach is required. This paper presents a method for localizing a sensor-equipped vehicle in a large-scale underground environment by using a particle filter and a collection of 2D a priori node maps. Sporadically placed passive RFID tags are used in the creation of the locally consistent node maps and...
Plug-in Hybrid Electric Vehicles (PHEVs) have less fossil-fuel dependency, lower carbon emissions and lower operating costs than the conventional vehicles. On the other hand, wide adoption of PHEVs is expected to increase the load on the power grid. Sensor web services have recently emerged as promising tools that can provide remote management, data collection and querying capabilities for the sensor...
