VANET gives the advantage to enhance road safety and assure less or no traffic accidents. However, false messages can result in serious conditions like collision. This paper proposed a new, trust based technique for location selection in VANET. In the paper presents a trust based location selection scheme has two phases computation of direct and indirect trust. However, evaluation of direct trust system using infrastructure (RSU) and trusted authority (TA) and evaluation of indirect trust uses watchdog approach. Results show that the proposed scheme suitable for the actual situation of VANET.

Mobile Ad hoc Network (MANET) is a particularly disputed network because of its particular features, for example, active topography, decentralization, as well as neighbor depend routing. In MANET, any mobile nodes can connect or disappear arbitrarily; thus, mobile nodes cannot awake which node is it joined with, and this creates resources been dealt between unknown nodes that can be trusted or not. As a result, without any trustworthiness makes the main susceptibility in security concerned aspects of the MANET. In this situation, trust value employs a vital function in all network performance. This paper introduces DempsterShafer theory and Encounter based Trust Routing (DETR) in a MANET. In this scheme, the direct trust and indirect trust is used to compute the mobile node trust. The node cooperation and encounter rate parameters measure the node direct trust in the network. The node indirect trust is computed based on the neighbour node opinion using DempsterShafer theory. Simulation results demonstrate that DETR detecting untrustable nodes in the network.


The recent developments in wireless communication technologies along with the costs of hardware allow both V2V and V2I communications for information exchange. Such a network is called Vehicular ad Hoc Network (VANET) which is very important for various road safety and non-safety related applications. However, Due to the wireless nature of communication in VANETs, it is also prone to various security attacks which are originally present in wireless networks. Hence to realize the highest potential of VANET, the network should be free from attackers, there by all the information exchanged in the network must be reliable should be originated from authenticated source. The system can be processed by the fuzzy logic method. It does not require any keys for data transmission. The system design is very efficient compared to other techniques. So the users prevent from road accident and traffic jam.

Accident prevention has always been an important issue for governments and car manufacturers across the world. Roughly 1.5 million people are killed in road accidents annually in India. The primary causes of accidents are broken and weathered roads, hazardous weather conditions, as well as human errors such as over speeding, distracted driving, and not following road safety rules. The traffic police work hard to enforce strict rules and maintain accident-free roads, but this hasn’t proven to be efficient. A vehicular ad hoc network (VANET), as the name says, is a network consisting of nodes. These nodes depict vehicles on the road. This project aims to use this technology with K-Nearest Neighbour Classifier (KNN) to create a prototype of a system which can notify drivers of an impending accident caused by forward collisions, rear collision etc., thus enabling them to take immediate action and prevent it.

Vehicular Ad hoc Network (VANET) is an advanced system and subcategory of a Mobile Ad hoc Network (MANET), it has as the potential to significantly impact road safety and improve traffic by providing critical information to drivers on critical routes. The system can inform the driver of a local anomaly, which is a very short distance from the sensors. Data from this sensors can be passing between vehicles so as to increase awareness of this environment. Intelligent Transport System (ITS) applications will include traffic efficiency, comfort of driving and road safety. The transaction of warning messages exploits a limited capacity because these applications generate little separate messages. Estimating the capacity of the VANET is therefore essential, as it may limit the deployment or usefulness of these applications. Therefore, an estimate must be made in advance for application design with capacity limitations in mind. VANET capacity is limited mainly through spatial reuse.  Multiple-Input Multiple-Output (MIMO) structures have been suggested to replace the conventional systems. In MIMO systems, a much higher data rate can be achieved than in a VANET environment. The objectives of the paper to study the capacity of the VANET network associated with new promising MIMO technology. Spatial multiplexing (SM),utilizes the spatial dimension to maximizethe capacity of a link without expanding a bandwidth. The SM gain is achieved throughtransmitting signals concurrently on parallel channels spatially with the same frequency. Capacity calculated over VANETs environments with MIMO/SM techniques, using Rayleigh Fading Channel with BPSK modulation. The results of MATLAB simulation package 2017a, indicate the enhancement in the unit of bit per second per Hertz (b/s/Hz). A maximum capacity improvement for MIMO system over Single Input Single Output (SISO) was achieved by using (4 x 4) system, it is about 16.14 b/s/Hz.

Effective message forwarding between vehicles can reduce the occurrence of traffic accidents and improve the driving experience. Vehicle clustering can improve message utilization, but attackers in the network pose a serious threat to message forwarding. Based on vehicle clustering, we propose a message forwarding strategy for Vehicular Ad hoc Network. Specifically, the vehicles are clustered based on their directions and speeds. Besides, the friendship of vehicles is evaluated in terms of the interaction friendship and reference friendship. Based on the friendship of vehicles, the optimal vehicle can be selected as the cluster head. Thereafter, the double key technology is designed to encrypt vehicular messages such that the messages can be forwarded more safely and efficiently. The analysis results show that the proposed strategy can effectively improve the message delivery rate, reduce the message leakage rate, and improve the network performance.


Security is one of the most vital aspect for implementing FANETs in adverse environments. Hence, research in this area has emerged as an important FANETs field in the recent past. Compared to wired networks, FANETs are more vulnerable to security attacks due to lack of a trusted centralized authority and easy eavesdropping. Further, as nodes in flying ad-hoc networks are susceptible to attacks, a trust model based on direct, as well as indirect trust degrees from similar trusted neighbors is integrated in order to overcome the vulnerability due to attacks by malicious/selfish nodes and to provide reliable packet transmissions. Fading away of trust is incorporated with a perspective to ensure the uncertainty of trust with time until it is updated. Also, AODV algorithm is used for routing in combination with calculated trust values so that efficient transmission of messages can take place.
