“…We define a cluster partition as a set of non-overlapping clusters that includes all the vehicles within the network. In the following, we consider only cluster partitions with clusters 1 For the given example application (constant uploading of Floating Car Data), every vehicle will be constantly sending its position information through the Base Station to a distant server. This is exactly what very wellknown mobile map applications do when collecting information about an user's daily trips.…”

Due to the increasing number of car-centered connected services, making efficient use of limited radio resources is critical in vehicular communications. Hybrid vehicular networks dispose of multiple Radio Access Technologies (RATs) like cellular and vehicle-to-vehicle (V2V) networks, with complementary characteristics that allow for developing smarter network traffic distribution methods. This paper proposes a self-adaptive clustering system for ensuring a suitable trade-off between data aggregation (over the cellular network) and communication congestion due to cluster management (within the V2V network). The systems algorithms use a distributive justice approach for selecting cluster heads, to improve fairness among car drivers and hence help the social acceptability of self-adaptive clustering. Simulation results show that this approach significantly improves fairness over time without affecting network performance. This solution can thus optimize the usage of radio resources, reducing cellular access costs, without the need for uniformization among different mobile operators access plans.

“…An effective VANET can enable high safety and traffic management, for the vehicle transportation [7]. But in this VANET some malicious nodes may interrupt the smooth communication, by creating issues like false data propagation, message suppression and denial of service [8,9]. In order to provide the secure data delivery, the researchers have proposed many systems including secure crash reporting, safety message sharing and cooperative collision avoidance etc.…”

Vehicular Ad-hoc Network (VANET) has wide application in developed/developing nations, for the effective management of vehicular traffic, and inter vehicular communication. In vehicular communication, the data includes traffic alert and safety warning. In most of the previous research achieved better quality in VANET routing. In some research, the researchers also proposed the security model for the secure transmission of these data. Instead of giving importance to the security of these data, trust ability of data and data transmitter is essential in VANET communication. In this paper a new protocol called Virtual Trust-ability Data transmission (VTD) is proposed for the effective handling of VANET. In the proposed protocol, three stages are used in the first stage a virtual topology is crated using a simple clustering technique. Then in the second stage the trust ability of every node or vehicle is analysed. In the last stage, the data are transmitted via the trusted vehicle and remove the false data from the communication. Then the performance of the proposed VTD protocol is analysed based on packet failure rate, bandwidth utilization and network scalability. The proposed VTD provided 94% of packet delivery ratio with 6% of the average packet failure. Similarly, the other performance also improved as compared to the conventional technique. So, it is clearly proving that the proposed VTD protocol can become a better alternate for the trust aware routing in VANET.

A Comprehensive Real-Time Traffic Map for Geographic Routing in VANETs

Vehicular Ad Hoc Networks (VANETs) have attracted a lot of attention during the last decade. VANETs can not only improve driving safety, but also convenience, and support most future Intelligent Transportation System (ITS). Due to the highly dynamic network topology of VANETs, many geographic routing protocols have been proposed and use real-time traffic information as an important metric to select a reliable forwarding path. However, most of the existing works do not describe how to gather real-time traffic. They either assume this information is already available, or can query an existing traffic center. Few studies have noticed this issue but the proposed solutions only consider a small region. In this paper, we propose a Comprehensive Real-Time Traffic Map (CRT Map) to collect wide-ranging real-time traffic information with low overhead. In the design of a CRT Map, the concept of Crowdsensing is adopted. Vehicles cooperatively gather traffic information and share it with each other to construct an overview of the whole road network traffic. In addition, we design a CRT Map Based Routing (CBR), which takes into account the connectivity of consecutive roads in routing decisions. Simulation results show that the CBR can achieve a lower end-to-end delay and a higher packet delivery ratio.
