Efficient And Privacy Preserving Routing Scheme

The solution to reduce in traffic jams is self-driving cars. These cars can follow more closely packed at higher speeds and as a result this saves time and reduces the need for more roads to be built. This is due to the intercar communication between self-driving cars that allow intelligent convoying. According to Will Knight’s “A simple wireless technology promises to make driving much safer” the technology that allows these cars to communicate is called car-to-car or vehicle-to-vehicle communication. This intercar communication lets cars broadcast their position, speed, steering-wheel position, brake status, and other data to other vehicles within a few hundred meters. The information given to the other cars can be used to build a detailed picture of what’s going on around them, uncovering trouble that even the best driver, or the best sensor system could miss or fail to anticipate. Communication between the cars would make traveling smoother they

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.

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.

Communications of data between vehicles is known as V2V, or vehicle to vehicle, and between vehicle and infrastructure is called V2I. With such a wealth of data flowing in the air, concerns are raised for the data security and privacy.

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.

Driven by the fundamental problems encountered due to identification and location conflation problem in IP networks and inefficiency of TCP for intermittent links, we propose a simple yet effective solution to provide access to advanced services for vehicular nodes with varying link conditions. To address aforementioned issues, we leverage cloud resources to design and develop a framework for connected vehicles. This scalable, mobility-centric solution, through network abstractions and clustering schemes with high resilience against failure, can provide seamless connectivity, global reachability, and enhanced connection for vehicular nodes with high dynamicity and possibly no direct association to an access point.

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.

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.

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

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.

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].
