Ad-hoc networks don’t have any Pre-established Network infrastructure or topology. An ad-hoc network in terms of wireless is a small LAN network in which each wireless have a ability to directly communicate with the other peer, especially in some wireless connections, in which some of the network nodes are part of the network only for the duration of a session or, in the case of mobile or portable devices, while in some close proximity to the rest of the network. Mobile Ad-hoc Network (MANET-Self configurable infrastructure less network) is a collection of independent nodes within the network that can communicate using radio waves as medium. The mobile devices that are in range can directly communicate, whereas others make use of intermediate nodes to route their packets. It uses the combination of ID based encryption and Group signature for route discovery. USOR provides security against both inside and outside attackers.
