While downloading the file requesting node will look for the neighbor node if they are in coverage then the cloud is created as shown in Fig(2). Node A requesting for download of a file, observes the neighboring nodes i.e., B and C. the VM is created on both the nodes B and C, all the three vehicles will download the file from the roadside cloud in this way the vehicle A will have the file before it moves out of the range of roadside infrastructure, as it moves out the remaining each part will be downloaded from the vehicle by using V2V communication. IV. SECURITY CHALLENGES As the information generated here is very sensitive that that need to be handled carefully. The security issues that may arise are listed in [6]. Providing authentication to each and every vehicle is the tedious task due to the high mobility, as vehicles will be sharing same physical infrastructure it’s difficult to keep the attacker at the bay. Though the attacker and target are located on different machines but they share same infrastructure in Vehicular cloud. The attacker can attack on confidentiality, integrity and availability. …show more content…
The integrity is nothing but tampering the information, the attacker may alter the information generated by the legal user. Availability, the attacker may change the privileges that make the resources unavailable to the target user. Problem of authentication in vehicular cloud is because of the frequent change in
A sound wave is a disturbance that repeats regularly in space and time and that transmits energy from one place to another with no transfer of matter. In Activity 2 on page 8 we had to model sound waves using an instrument. In our class we used a flute as the example and when the person blew into it, sound waves were produced. As they blew and changed the volume and pitch the sound waves changed. A sound wave is created when something vibrates. When something vibrates, longitudinal waves are created which we can hear. A longitudinal wave is a wave that transfers energy through compressions and rarefactions in the material that the wave travels which are all parts of a sound wave. In Activity 2 it states in some parts of the wave, the air molecules
The subject with type first and type second diabetes who does not receive standard care, comply with the prescriptions or poorly controlled metabolism regarded by the test physician.
Chapter 4 - Describe the impact on users of migrating from a small single server-based network to a directory-based network with multiple servers in different roles. Also describe the impact on network designers and administrators.
The iBooks Author format is only able to be read in the iBooks ecosystem, and it can only be created in the iBooks Author program on a Macintosh computer.
Once the medical records have been converted to electronic medical records. There are two options, one is to shred the original documents. The other option is to store them in a storage where they will be locked away. They will always be available to be viewed whenever need be. I personally would keep the files in a locked storage for about a year or two to see if it would make life easier before shredding the documents.
The accompanying directions were formed for introducing Sun Java 1.5.0_08 (otherwise known as JDK 5.0 refresh 8). This may not be the most recent variant, but rather the one we are utilizing this semester. Note: Java is as of now introduced as a feature of Mac OS X, so no further establishment is essential for these machines. Guarantee, however, that you have the correct form by writing java - rendition to the unix order provoke; the reaction ought to be something like java adaptation "1.5.0_08" A run of the mill Java establishment takes around 400 megabytes of circle space. The establishment procedure reports the correct size.
One of the largest features in Java 8 was the ability to stream over collections of objects. By adding the .stream()-method into the Collection interface, every collection in the java language was suddenly expanded with this new ability. Other data structures like the Map-interface, does not implement the method as they are not strictly speaking collections.
Quantitative risk analysis involves steps, calculations and tools to have a good analysis. The steps involve with this method from (wikibooks n.d) includes: assigning value to assets, Estimating potential loss per threat, Performing a threat analysis and Deriving the overall loss potential per threat. Firstly, in order to assign an accurate value to an asset, all tangible and intangible assets must be identified. For instance a company may have a server and to determine the value of the server, the important of the server to the company and the cost of losing server are factors that helps in determining the value for the server. Secondly, the potential loss per threat should be estimated. If a server is hacked, how much loss will it cost to the company? To know that, the Single Loss Expectancy (SLE) has to be calculated. SLE is the asset value (AV) times the exposure factor (EF). Thirdly, risk analysis have to be performed. In the case of a server being stolen, it has to be determine how many times in a year can it happen. To know this, the Annual Rate of Occurrence (ARO) have to be calculated. Also, the overall loss potential per threat have to be known. The overall loss that can be incur from a stolen server and the probability that a server will be stolen can be derived by calculating the Annual Lost Expectancy (ALE) which is annual rate of
and the second path is where ten is added to the value of the entrance and then the subtraction occurs. On the side you can see a series of logic gates that generate a function that will produce an output of 1 only when digit 1 of the exit is bigger than that of the entrance. This output will be sent to two different multiplexers, one for each digit. In the digit 1 diagram it will be sent to a multiplexer that will decide whether to use the subtraction where the entrance has been increased by 10 or whether to use the other where the entrance has had no alteration. If it is a 1, then it will use the first option where ten was added to the entrance. If it is a zero, then the latter will be used. This can be seen below in figure 2.
Actually,you are required to comply with two different sections. The top chord must satisfy section 8.6.5.1 and the web components must comply with 8.6.5.2. I understand you’ve placed the sprinkler 2-ft away from the top chord that satisfies Table 8.6.5.1.2. One could argue that these are not structural members so 8.6.5.2.1.4 allows you to ignore them. Although that would meet the letter of the standard, it would not meet the intent. As required by 8.6.5.2.1.3, you need to be located away from the obstruction a minimum distance of 3 times the maximum dimension of the obstruction. That would be 9 in. away from the vertical web components and 6 in. away from the diagonal components. The 2-ft separation dictated by the top chord obviously complies
The concept of internet of vehicle is shown in Fig.10. The converging technologies of IoV are related to electric vehicle, autonomous vehicle etc. The IoV can also deals with the vehicle to vehicle (V2V), vehicle to device (V2D), vehicle to infrastructure (V2I) and vehicle to grid (V2G) communication.
The objectives of vehicle to vehicle and vehicle to infrastructure communications are to avoid the vehicle crashes, to examine the technological issues that may affect this short range communications, characterise the communication needs of particular vehicle security applications, to monitor the vehicles that breaches the law etc.
Vehicular communications (VC) will play a vital role in enabling safer, smarter and greener transportation, with envisioned applications providing, for example, warnings on environmental hazards (e.g., ice on the pavement), traffic and road conditions (e.g., emergency braking, congestion, or construction sites), and local (e.g., tourist) information.
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
The paper examines the emerging application that can be provided and the vehicle oriented internet services. These have been the first steps towards mobile vehicle architecture.
