Efficient And Privacy Preserving Routing Scheme

2. The road side units start analyzing the bandwidth consumption of each vehicle node and node which is using the bandwidth above allocated value will be the malicious nodes

Self driving cars have become a reality but they still require help of humans to operate it. Although there has not been a perfect working model of self driving car, big companies like Google are working on this type of car’s testing (Cohen, 2015, p. 329). According to the author, autonomous cars can be extremely beneficial to people who cannot drive on their own. On the other side, it has more disadvantages such as hacking, and tracing the device and insurance policy issues. At last, author expects new laws with the launch of self-driven cars regarding protection and liability made by the customers.

Becoming a safe vehicular user categorizes as the most important procedure of becoming a starting driver. In addition, knowing the how to of driving could potentially save a driver’s life as well will prevent disastrous situations. This essay will cover two topics; however, there remains a plethora of tasks to be pursued before and during driving. For one, a safety belt is very important when it comes to the safety of the automobilist and for comfortability. Continuing on, this paper will cover how to follow the speed limit of the specified road. For every vehicular user’s security, these rules and regulation must be specifically followed.

There are many characteristics and challenges that should be taken into consideration when developing multicast routing protocols, like the dynamically changing network topology, limitation of network scalability. There are different types of protocols like unicast protocols [1], [2], cluster based protocols [3] In this paper we discuss about multicast routing for vehicular Ad hoc network which is different from other Ad Hoc networks [4]. Generally there are two types of multicast routing protocols in wireless networks. Tree-based multicast routing protocol, mesh based routing protocol [5]-[8]. In the tree-based multicasting, structure can be very much unstable in multicast ad-hoc routing protocols, as it needs frequent re-configuration in

A review over the various techniques which used for key management in VANET is presented in this section.

Abstract: Because of high speed of vehicles, short contact durations and rapid changes in topology occurs in Vehicular Delay Tolerant Network (VDTN). This will generates few transmission opportunities and high and unpredictable delay. This problem can be solved by different routing protocol of VDTN. The VDTN protocol can be divided as single copy and multi copy. In single copy protocol the node is allowed to generate the unique copy of message and forward it on a unique path. The multi copy protocols generate and transmit the multiple copies of each message and forward it along various paths. If more number of copies spread in network there are more chances for successful transmission. The objective of paper is to improve performance of VDTN by modifying existing Spray and Wait protocol. In this paper we provide proposed algorithm for modify spray and wait protocol for improving delivery probability with different number of message copy. The modifications based on stored number of message copies at source/rely nodes and encountered nodes ratio.

Abstract— A step towards the research of wireless time-triggered networks was taken with the development of a new safety-critical wireless protocol called the Time-Triggered New Zigbee (TTNZ) protocol. The methodology for developing the TTNZ protocol involved Model Driven Engineering (MDE) and a tool called TimeMe which is an IEC 61499 standard compliant software. MDE overcomes the limitations of the traditional approach which does not guarantee consistent performance during the design and development phases of a Wireless Sensor Network (WSN) [1]. This safety-critical wireless protocol, TTNZ, does not take into consideration the irregularities of the physical (PHY) layer. The current project is undertaken to consider the issue of timeliness with PHY layer abnormalities and accordingly use a measurement or testing based approach to verify timeliness.

Vehicular Communication System plays a major role in the development of Intelligent Transportation System(ITS) which enable the users to make safer, and 'effective ' use of transport networks and aim to provide innovative services relating to different modes of transport and traffic management.In

Mobile Ad-hoc Network (MANET) attached in a dynamic manner and it is an assembly of wireless mobile nodes. Without any fixed infrastructure nodes making a temporary network where all nodes are arbitrarily free to move. In the network nodes are act as routers, which take part in finding and maintenance of routes to other nodes [1]. Wireless connection in MANET is highly misplay and due to mobility of nodes it goes down usually. Due to highly dynamic environment coherent routing is a very difficult task in Mobile Ad-hoc Network [2].

Safety and security of a vehicle is a foremost requirement of its owner. Hence, equipping your vehicle with a smart system well ensure full proof mechanism for the vehicle’s safety [1]. This system enhances efficiency

Abstract Vehicular communication based on short-range wireless technology opens up novel applications improving road safety and travel comfort. Ad hoc networking enables a direct communication among cars as well as between cars and road-side communication devices. Geocast is an ad hoc routing scheme which is specifically considered in Europe as a core networking concept for future CAR-2-X systems. It provides wireless multi-hop communication and allows for geographical addressing and routing. This paper describes advanced concepts and mechanisms to deploy

With the drop of the hardware cost, more and more mobile devices with higher capacities are now used. The widely deployed wireless LAN and broadband wireless networks provide the ubiquitous network access for multimedia applications. Provision of Quality of Service (QoS) is challenging in mobile ad hoc networks because of the dynamic characteristics of mobile networks and the limited resources of the mobile devices. The wireless network is not reliable due to node mobility, multi-access channel and multi-hop communication.

The evolution of wireless technologies in modern days helps to utilize these kind of technology in many applications like vehicle safety application, a wireless data communication between the vehicles and also between the vehicles and other infrastructure.

Vehicular Ad-hoc networks are used in order to improve the Traffic Efficiency and road side safety.

Car to car communication is a leading technology that may hit the market in upcoming two –three years .The technology that warns for imminent collision will be in cars soon and it will help car to transit their position, speed, steering wheel position and other data with other cars within 100 meters. Many cars have tools that use radar or ultrasound to identify the hurdle but the range of sensor is limited to certain length and they can’t detect the obstacle. So this technology which use higher-level technology which can be helpful in many prospects. Technologies thatC2C Communication uses are Dedicated short range communication (DSRC), Wireless LAN, GPRS, CLOUD, Mesh Network, This technology is reviewed by MIT and General
