“Ad Hoc” comes from Latin, which means “For the specific purpose only”. An Ad Hoc network is a multi-hop temporary self-organizing network consisting of a group of mobile terminals with wireless transceivers. It does not have any control center or basic communication facilities. It is also called a wireless self-organizing network. All nodes in an Ad Hoc network have equal status, and no central node is required to control or manage the network. Therefore, damage to any terminal will not affect the communication of the network, and it has strong anti-destruction capabilities. Each node not only has the functions of an ordinary mobile terminal, but can also forward data to other nodes. When the distance between two nodes that need to communicate is greater than the distance for direct communication, the middle node forwards data for them to achieve mutual communication. Sometimes the distance between two nodes is too far, and the data needs to be forwarded by multiple intermediate nodes before it can reach the destination node.
