The functions of profile management were implemented in the community layer. The authors provided an architecture comprising four layers, namely, application, community, network, and device layers. considered ASN as the extension of the online social network to further increase global communication. The authors used the dynamic source routing ad hoc network protocol to deploy the multihop social network. introduced the multihop social network to broadcast promotional offers to nearby users without using the Internet or GPS. The service alerted users of similar interests in a nearby region. Eagle and Pentland introduced a service to introduce proximate users by doing profile matching at a central server. The ad hoc social network (ASN) has the potential to connect nearby users who should be connected based on similar interests.
Section 4 provides architecture and implementation comprising key components used for location-based ad hoc social networking. This paper is organized as follows: Section 2 provides the review of related publications. The mechanism can be used to further develop applications to cater needs of business users to distribute business cards during international conferences, seminars, or meetings for networking when people may have smartphones but do not have access to the Internet. This paper presents a Wi-Fi peer-to-peer-based mechanism called OffAT (OFFline chAT) that helps to find people with similar interests in a nearby region and allows sharing text or handwritten messages without any centralized server. Furthermore, ad hoc social network can help to communicate in case of natural disasters or government censorship.Īd hoc wireless peer-to-peer technology connects devices to create a communication group for social interaction. Another application is communication among passengers in an airplane for game playing by children especially when the flight duration is long or for anonymous chatting among interested passengers or with crew members.
There are numerous applications for example, it may also be useful in a business meeting where the distribution of physical business cards is not a convenient method, but the e-cards can be conveniently distributed in a peer-to-peer network to all individuals present nearby. Īd hoc social network, one-to-one or multipeer connection, can solve this problem of privacy and help facilitate the communication in a nearby region without using the centralized infrastructure. Thus, the current trend is to decentralize the online social network. Furthermore, limited data plans for the mobile device and high cost of international roaming constraint users to communicate even in the nearby region. However, current social networking applications do not provide location-based services without accessing the present site of a user, and many users consider this a privacy risk. Examples of location-based social networking include the Facebook’s feature to find exotic locations or friends nearby in a geographical region. The pattern of using social networking on the mobile device is being exploited by researchers and service providers to provide location-based social networking. Online social networks, for example, Facebook, LinkedIn, or Twitter, are now highly popular among people, and the trend to use the social networking applications on the mobile device is continuously increasing. The peer-to-peer group can be used for private communication when the network is not available. The application connects users to form a group based on their profile or interests using the peer-to-peer communication mode without using any centralized networking or profile-matching infrastructure. The broadcasting region creates a digital aura and is limited by the Wi-Fi region that is around 200 meters. This paper presents an architecture and implementation of social networks on commercially available mobile devices that allow broadcasting name and a limited number of keywords representing users’ interests without any connection in a nearby region to facilitate matching of interests. However, current ad hoc social network applications either are not available without rooting the mobile phones or do not filter the nearby users based on common interests without a centralized server. It allows users to collaborate and share views anytime anywhere. Unlike traditional social services using a centralized server to fetch location, ad hoc social network services support infrastructure-less real-time social networking. Ad hoc social networks have become popular to support novel applications related to location-based mobile services that are of great importance to users and businesses.
