Abstract: Ad-hoc Social Network (ASN) is a blend of social network and ad-hoc network. Today most of mobile phones are equipped with Bluetooth, Wi-Fi, and Cellular radio and so are capable of supporting ad-hoc communication mode. ASN is a social network where people of similar interests connect with each other using ad-hoc communication mode of mobile devices. ASN has its own advantages as it uses infrastructure-less network for communication. ASN is more meaningful as users are interested to know which of other users have similar interests and are within communication range so that they can either chat or personally talk on current interests.
