Pattern design plays a vital role in establishing network communication in Ad-hoc network scenario. The real challenge to the researchers is designing the communication architecture to vehicular network. Vehicular network architecture design is difficult, since the movement of the vehicle speed is high. The existing vehicular network architecture forms the network communication but the communication is not reliable and the message transmission time is high. However a new architecture design is required to establish fair network communication among vehicles. This paper presents a novel cluster based vehicular network architecture for Manhattan Mobility Model and the proposed model is analyzed with various routing protocols. The result and analysis of the proposed model show clearly that the Cluster based Manhattan Mobility Model produces reliable communication. The proposed Cluster scheme reduces the message transmission time obviously.

Online Social Network (ONS) is the easiest platform to connect with one another. There are many Online Social Networking websites exist to bring up the reliable communication among the users. Facebook, Orkut, Google+, Twitter, MySpace, etc are some of the Online Social Networking websites. All the social networking websites provide the interface formally known as profile, to share their willingness with others. The users of these websites could share their feelings, photos, text file and even whatever the user wishes to provide. All the Online Social Networking websites bring the friends, family members and relatives together to share their desires in a fast track manner, however still it lacks in security module. The shared photos and information are freely open access to all the users of social networking websites. When the photos are freely available, the unauthorized users can easily access the photos of others and download it. Once the photo is downloaded, that image can be misused widely such as creation of fake profile and the photo can be sold to other nuisance websites. This kind of data hacking activities in online social networks even leads the life to death. In this paper, data hacking in online social network is considered and a novel mechanism is presented to prevent the data hacking.
