TL;DR: In an effort to develop a complete DSRC system for ITS application, the authors have studied a lot of experimental facts which they are exploiting for the design and a fixed wireless connectivity at Ku band is explored for road side base station to master switching center connectivity.
Abstract: In an effort to develop a complete DSRC system for ITS application, the authors have studied a lot of experimental facts which they are exploiting for the design. The wireless technology has been chosen properly which is capable of tackling the severe interferences present in the open road. For road to car communication, a combined digital technology like spread spectrum along with diversity reception will help a lot in this regard. Accordingly, the choice is for FHSS based space diversity system which will utilize carrier frequency around 5.8 GHz ISM band with available bandwidth of 80 MHz and no license. For efficient design, the radio channel is characterized on which the design is based. To have the full DSRC system, a fixed wireless connectivity at Ku band is also explored for road side base station to master switching center connectivity.

TL;DR: With this kind of challenging efforts, the authors will like to converge two important fields of electronics ‘remote sensing’ and ‘mobile communication’ together in intelligent vehicular operation.
Abstract: Attempts are made in realization of the trend noticed for smart vehicle in terms of vehicular safety and communication. A Doppler radar is established at the Laboratory and tested on road for vehicular detection. In order to improve the detection performance further and more meaningful, range, classification of vehicles, angle of arrival information are also required to be measured. Additionally communication part is also embedded into the system. The embedded system design is almost finalized. The end to end simulation efforts are going on. Parts of the implementations are also tried. With this kind of challenging efforts, the authors will like to converge two important fields of electronics ‘remote sensing’ and ‘mobile communication’ together in intelligent vehicular operation.

TL;DR: The Software Defined Radio approach is started for best speed and flexibility in wireless radar system for reducing the world road accident by 8-10% yearly.
Abstract: Scientists and Technologists involved in the development of radar and remote sensing systems all over the world are now trying to involve themselves in saving of manpower in the form of developing a new application of their ideas in Intelligent Transport system(ITS). The world statistics shows that by incorporating such wireless radar system in the car would decrease the world road accident by 8-10% yearly. The wireless technology has to be chosen properly which is capable of tackling the severe interferences present in the open road. A combined digital technology like Spread spectrum along with diversity reception will help a lot in this regard. Accordingly, the choice is for FHSS based space diversity system which will utilize carrier frequency around 5.8 GHz ISM band with available bandwidth of 80 MHz and no license. For efficient design, the radio channel is characterized on which the design is based. Out of two available modes e.g. Communication and Radar modes, the radar mode is providing the conditional measurement of the range of the nearest car after authentication of the received code, thus ensuring the reliability and accuracy of measurement. To make the system operational in simultaneous mode, we have started the Software Defined Radio approach for best speed and flexibility.

TL;DR: A cooperative load balancing approach among RSUs is proposed, in which an RSU can transfer the overload requests to other RSUs, which outperforms the non-cooperative (stand-alone) approaches in a wide range of scenarios based on performance metrics.
Abstract: For overcoming the vehicle to vehicle frequent disconnection problem in VANETs data dissemination, several approaches have been proposed, including the provision of Road Side Units (RSUs). Due to the short wireless transmission range of RSUs and vehicle mobility, a vehicle spends only a short period of time inside the range of an RSU. This limitation, together with possible overload of RSUs sited near busy road junctions, may mean that requests from vehicles are not served within the prescribed deadlines. In this paper, we propose a cooperative load balancing approach among RSUs, in which an RSU can transfer the overload requests to other RSUs. Load transfer is done based on a number of factors: request delay tolerance, current load of the transferee RSU, and the direction in which the vehicle is heading. Using a series of simulation experiments, we demonstrate that the proposed cooperative load balancing approach outperforms the non-cooperative (stand-alone) approaches in a wide range of scenarios based on our performance metrics.

TL;DR: This paper proposes a collaborative certificate status checking mechanism called COACH to efficiently distribute certificate revocation information in VANETs and proposes an extension to the COACH mechanism called EvCOACH that is more efficient than COACH in scenarios with relatively low revocation rates per CRL validity period.
