VANETs are enhanced and upgraded versions of mobile ad-hoc networks which are fruitful for intercommunication vehicles. Communication can be vehicle-to-vehicle and between vehicles to side-fixed equipment known as roadside equipment. This network is self-organized, highly dynamic but separated without any infrastructure or client and server communication. The objective of this research is to examine the study of TwoRayGround and Nakagami radio propagation models for vehicular ad-hoc networks in Indian Scenarios as well as to find the best efficient model, which is more suitable in various scenarios. Output of this research will be beneficial for applying efficient models on the realistic highway scenario, especially traffic caused by four wheelers. This model will also be fruitful for avoiding heavy road congestion and highway road accidents caused by a high and unbalanced speed of traffic as well as other various road conditions, like pot holes and road barriers, etc.

Vehicular Ad-hoc Networks (VANETs) is an emerging network technology derived from ad-hoc networks. This paper provides the state-of-the-art of VANETs and provides optimum proposal by improving Quality of Service (QoS.) Today, wireless systems are preferred over wired systems and these are gaining popularity as it provides wireless connectivity to the users irrespective of their geographic position, VANET is one of them. VANETs are installed to minimize the risk of road accidents and to improve passenger comfort by permitting the vehicles to exchange various types of data. In this paper, the Signal Strength based Optimum Path Selection (SSOPS) based solution on how to mitigate the QoS issues that exists while using the existing methods are discussed. Moreover, the solution has been tested using NS2 software using various parameters.

India accounts for the highest road accidents and traffic congestion globally. The necessity for a canny vehicle framework is of great importance. VANET, abbreviated as Vehicular ad hoc networks is a network created in an ad hoc manner where different vehicles can exchange useful information among each other with dedicated servers ensuring safe travel. Security in VANET has always been a challenge in implementing a real time intelligent transport system. VANET is a type of mobile ad-hoc, to give correspondences among close by vehicles and among vehicles and close by fixed hardware. Vehicular ad hoc networks are highly dynamic in nature and suffer from frequent path breakage due to the high velocity of the moving vehicle. Hence, there are many security challenges and different types of attacks that makes VANETs less secure. Therefore, providing secure dedicated short-range communication (DSRC) easefully with any loss of data or malicious nodes has been a major research area. The major concern being addressed in the paper is to provide secure communication and save lives in road accidents. The role of security is high and messages in DSRC send warning messages to other vehicles. If attackers change these messages, then accidents become a part of the network and users’ lives can be at risk. Different classes of attacks include monitoring attack, social attack, timing attack, application attack and network attack to name a few. Advanced encryption standard is a symmetric block encryption algorithm. There is no evidence to crack this algorithm till date. This paper will provide a detailed overview of VANET architecture, types of attacks on VANET, AES algorithm and its salient features and how this algorithm could be utilized to make intelligent transport systems secure.

The past decade has witnessed the emergence of Vehicular Ad-hoc Networks (VANET), specializing from the well-known Mobile Ad Hoc Networks (MANET) to Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) wireless communications. While the original motivation for Vehicular Networks was to promote traffic safety, recently it has become increasingly obvious that Vehicular Networks open new vistas for Internet access, providing weather or road condition, parking availability, distributed gaming, and advertisement. In previous papers [27,28], we introduced Cooperation as a Service (CaaS); a new service-oriented solution which enables improved and new services for the road users and an optimized use of the road network through vehicle's cooperation and vehicle-to-vehicle communications. The current paper is an extension of the first ones; it describes an improved version of CaaS and provides its full implementation details and simulation results. CaaS structures the network into clusters, and uses Content Based Routing (CBR) for intra-cluster communications and DTN (Delay–and disruption-Tolerant Network) routing for inter-cluster communications. To show the feasibility of our approach, we implemented and tested CaaS using Opnet modeler software package. Simulation results prove the correctness of our protocol and indicate that CaaS achieves higher performance as compared to an Epidemic approach.

Self-Organized Networks (SONs) are an advancement of today's communication that arises to overcome the problems in traditional communications in terms of their planning, configuration, optimization, healing and management since the rate of utilizing communication technology is gradually increasing day by day hence an optimum mechanism is needed to cope up with all the changes in the communication era, the result is self-organized networks. The success of SONs depends on how it is effectively utilized without any compromise in its security. However its unique characteristics offer both opportunities and challenges. The aim of this chapter is to begins with the essential concept of SONs such as Mobile Ad Hoc Networks (MANET), Vehicular Ad Hoc Networks (VANET), Wireless Sensor Networks (WSN), Wireless Mesh Networks (WMN), Peer to Peer Networks (P2P), Cognitive Radio Networks, Bio-Inspired Networks and Internet of Things (IoT) and their limitations in different perspectives. As these networks have penetrated into the human life with an anytime anywhere capability, the security of the data being processed and communicated through these networks become vital. This chapter tries to bring out the issues and challenges in providing a trust based solution mechanisms for this type of networks.
