In wireless network can classified in two way one is infrastructure network and another is infrastructure less. Infrastructure less wireless network is known as Ad-hoc network. An ad-hoc network is a Local Area Network (LAN) that is built spontaneously as devices connect. Instead of relying on a base station to coordinate the flow of messages to each node in the network, the individual network nodes forward packets to and from each other. "Ad-hoc" word is actually a Latin word its means "For this purpose." It is often used to describe solutions that are developed for a specific purpose. In computer networking, an ad-hoc networks all nodes are mobile and can be connected dynamically in an arbitrary manner.
