There are two modes of networking; infrastructure mode and ad hoc mode. In infrastructure mode, we use a central device like router or Access Point to connect all devices. This central device share Internet and files among devices connected to it. If you establish a direct connection between two devices without a router or AP, it is called an ad hoc network. In ad hoc mode, we can share the Internet and data between computers. That means in an AD-Hoc network, there is no base station to control and coordinate the packet flow. Here packets are flowing from one computer to another directly and can be compared with walkie-talkies because participating devices communicate directly with each other without any third party devices.
Windows support ad-hoc networking. For example, if you want to share a broadband connection on your laptop with other computers in your home, you can simply do it by establishing an ad-hoc connection. Once you have created such a network on your PC, it can connect another device in the same mode and start sharing files or broadband. To create such a connection, follow the instructions below.
To establish a connection between two computers without using a router, we need assistance from certain protocols called ad-hoc routing protocols. Here to participate to such a network without the base device, it needs to announce itself. These protocols help to automate this process. Major ad-hoc routing protocol types are Pro-active routing, Reactive routing, Flow oriented routing, Adaptive routing, and Hybrid routing. Some of them are listed below.
Though seems simple, this type of connection has a maximum limit of devices supported. There is a maximum limit of computers that can be connected to an ad hoc connection. If you follow the link below, you will see a pdf file which explains the limitations of this type of network.

Create Ad hoc Network
Windows support ad-hoc networking. For example, if you want to share a broadband connection on your laptop with other computers in your home, you can simply do it by establishing an ad-hoc connection. Once you have created such a network on your PC, it can connect another device in the same mode and start sharing files or broadband. To create such a connection, follow the instructions below.
- Go to Control Panel
- Click on Network and Sharing Center
- Click on Setup a New Connection or network link
- click on Setup a wireless ad hoc
Click next - Now you will get a warning to keep 30 feet as the maximum distance between PCs participating in this connection.

The duty of Ad Hoc Routing Protocols
To establish a connection between two computers without using a router, we need assistance from certain protocols called ad-hoc routing protocols. Here to participate to such a network without the base device, it needs to announce itself. These protocols help to automate this process. Major ad-hoc routing protocol types are Pro-active routing, Reactive routing, Flow oriented routing, Adaptive routing, and Hybrid routing. Some of them are listed below.
- Ad-hoc Wireless Distribution Service (AWDS)
AWDS is a Layer 2 wireless mesh routing protocol works in the Pro-active routing technology. - Clusterhead Gateway Switch Routing protocol (CGSR)
- Multirate Ad-hoc On-demand Distance Vector Routing Protocol
- Hybrid Routing Protocol for Large Scale Mobile Ad Hoc Networks (HRPLS)
- Hybrid Ad Hoc Routing Protocol
