Ad-hoc networks are infrastuctureless, self-organizing networks. They don't have fixed infrastructure. Topology in ad-hoc networks is dynamic as nodes join and leave the network \"On the fly\" whenever there is a need either to transmit data or when transmission gets over. These networks do not have a central authority for the management of the network. Here hosts rely on each other to keep the network connected. As the topology of the ad-hoc network is dynamic and every transmission is on the air these networks become vulnerable to number of attacks and security becomes a major issue.
