An ad-hoc network is a type of temporary computer-to-computer connection. In ad-hoc mode, you can set up a wireless connection directly to another computer without having to connect to a wireless access point or router.

| Wireless Ad-hoc Network |
A wireless ad-hoc network is a decentralized type of wireless network. The network is ad-hoc because it does not rely on a preexisting infrastructure, such as routers in wired networks or access points in managed (infrastructure) wireless networks. Instead, each node participates in routing by forwarding data for other nodes, and so the determination of which nodes forward data is made dynamically based on the network connectivity. In addition to the classic routing, ad-hoc networks can use flooding for forwarding the data.
An ad-hoc network typically refers to any set of networks where all devices have equal status on a network and are free to associate with any other ad- hoc network devices in link range. Very often, ad- hoc network refers to a mode of operation of IEEE 802.11 wireless networks
The earliest wireless ad-hoc networks were the "packet radio" networks (PRNETs) from the 1970s, sponsored by DARPA after the ALOHA net project.
Wireless ad-hoc networks can be further classified by their application: - Mobile ad-hoc networks (MANET)
- Wireless mesh networks (WMN)
- Wireless sensor networks (WSN)
