06 Jun 2011TL;DR: GeoVanet is proposed, a DHT-based geographic routing protocol which ensures that the sender of a query can get a consistent answer and is aimed at ensuring that the user will be able to retrieve the result within a bounded time.
Abstract: A vehicular ad hoc network (VANET) is a type of mobile network whose nodes are traveling cars and which communicate with one another using short-range wireless communications. These cars can exchange and share different information among them, which can lead to the development of interesting applications that require the cooperation of vehicles or using the vehicular network as a distributed computing platform. Along with the opportunities offered by vehicular networks, a number of challenges also arise. In this paper, we focus on information gathering in vehicular ad hoc networks by using a pull model. Such model would allow users to send queries to a set of cars in order to find the desired information. In order to propose such a query processing scheme, the main challenge to address is how to route the different results towards their recipient in a highly dynamic network where the nodes move very quickly. To solve this, we propose GeoVanet, a DHT-based geographic routing protocol which ensures that the sender of a query can get a consistent answer. Our goal is not to compute the query result "instantaneously" but to ensure that the user will be able to retrieve it within a bounded time. To prove the effectiveness of GeoVanet, an experimental evaluation is provided, which shows that up to 80% of the available query results are delivered to the user.

23 Oct 2014TL;DR: An embedded communication system is developed for small automatic electric vehicle, and an algorithm to avoid transmit collision is implemented in the developed system, and a platooning control system including vehicle interruptions and separations is successfully designed.
Abstract: Driving assistant systems with cameras and sensors are expected as a solution of safe driving, congestion prevention and driving load reduction and vehicle to vehicle (V2V) communication systems that utilize wireless technology has been proposed as an auxiliary system of the existing systems. On the other hand, as long with the increasing of the aging rate of society, traffic accident of seniors become a serious problem to be solved. Smarty automatic driving system has been developed to realize a smarty platooning control system based on the automatic driving system for senior drivers. In this research, an embedded communication system is developed for small automatic electric vehicle, and an algorithm to avoid transmit collision is implemented in the developed system. Based on the vehicle to vehicle communication, a platooning control system including vehicle interruptions and separations is successfully designed. Some experiment results of several platooning patterns for small EV represent the effectiveness of the developed system.

TL;DR: A cross-layer communication protocol is proposed to enhance OSS-TWR by compensating for the impact of network collision and a time-recordable back-off algorithm is proposed that can record the total back- off time for a frame resend resulting from a network collision.
