A wireless ad-hoc network consists of a collection of mobile nodes that communicate with each other via wireless links without the help of any pre-existing infrastructure. Each node can function both as a router and as a host. In other words, the nodes communicate directly with each other if they are in the same range of transmission, otherwise, intermediate nodes will be involved to forward the messages. Unlike wired networks, MANETs are more vulnerable to attacks.
