The basic structure of an Ad Hoc network is :
Computer 1<---------> Computer 2
The term ad hoc is mainly used in wireless networking. In wireless networking there are two types of networks.
1. Wireless Infrastructure mode
2. Wireless ad hoc mode
Wireless infrastructure networks works with the help of wireless routers where wireless ad-hoc is not using any wireless router or Access Point.
There are some protocols which supports Ad Hoc networks. That protocols are called Ad-Hoc routing protocols.
Duty of Ad Hoc routing protocols
Unlike other networks ,which uses router as a base station , a new computer in ad-hoc network should announce itself to others. The Ad Hoc routing protocols helps to automate the process. In Wikipedia we can see a list of ad-hoc network routing protocols. The major ad-hoc routing protocol types are Pro-active routing, Reactive routing,Flow oriented routing,Adaptive routing and Hybrid routing. Some of the important ad-hoc network routing protocols are provided below.
1. Ad-hoc Wireless Distribution Service (AWDS)
AWDS is a Layer 2 wireless mesh routing protocol works in the Pro-active routing technology.
2. Clusterhead Gateway Switch Routing protocol (CGSR)
This is also a protocols which works in Pro-active routing technology.
3. Multirate Ad-hoc On-demand Distance Vector Routing Protocol
It works in reactive routing technology.
4. Hybrid Routing Protocol for Large Scale Mobile Ad Hoc Networks (HRPLS)
This protocol is used for Large Scale Mobile Ad Hoc Networks with Mobile Backbones.
5. Hybrid Ad Hoc Routing Protocol
The actual capacity and maximum allowed number of nodes for an ad-hoc network
It will be really interesting to check the actual capacity of Ad-hoc networks. There is paper work done for checking the actual capacity of an ad-hoc network. To Check the capacity of an ad-hoc network click on the link below.
