Ad hoc has the following characteristics:
Wireless ad hoc networks are collections of nodes equipped with wireless transceivers that communicate exclusively over a common wireless channel.
Due to the nature of the wireless channel, each node can only communicate directly with a few other nodes lying in its neighbourhood. On the other hand, the traffic requirements of the network are such that distant nodes may need to exchange data.
Therefore, the nodes intermediate to such communicating pairs must relay data in a multi-hop fashion. The establishment of the network and its operation must be exclusively over the wireless channel, and in a distributed and decentralized manner [1].
Ad hoc networks should be constructed rapidly. Contrary to cellular networks, where an extensive infrastructure must be installed, ideally, wireless ad hoc networks should be formed automatically whenever any number of users happen to be in proximity to one another.
This speed of deployment is very important in a variety of applications, such as networks used in military or autonomous vehicle operations.
