A mobile ad hoc network (MANET) is a type of wireless ad hoc network, and is a self-configuring network of mobile devices connected by any number of wireless links. Every device in a MANET is also a router because it is required to forward traffic unrelated to its own use. Each MANET device is free to move independently, in any arbitrary direction, and thus each device will potentially change its links to other devices on a regular basis. The primary challenge for building a MANET is for each device to continuously maintain the information required to properly route traffic.

Such networks may operate in a standalone fashion, or may be connected to the larger Internet.

MANET are special cases of several other types of wireless and mesh networks, but have some key differences, at least in common usage, as listed below:

MANET are sometimes referred to as mobile mesh networks[1].

MANET have became a popular subject for research as laptops and 802.11/Wi-Fi wireless networking became widespread in the mid to late 1990s. Many of the academic papers evaluate protocols and abilities assuming varying degrees of mobility within a bounded space, usually with all nodes within a few hops of each other, and usually with nodes sending data at a constant rate. Different protocols are then evaluated based on the packet drop rate, the overhead introduced by the routing protocol, and other measures.

[edit] Types of MANET

Vehicular Ad Hoc Networks (VANET) are a form of MANETs used for communication among vehicles and between vehicles and roadside equipment.

Intelligent vehicular ad hoc network (InVANET) is a kind of Intelligence in Vehicle(s) which provide multiple autonomic intelligent solutions to make automotive vehicles to behave in intelligent manner during vehicle-to-vehicle collisions, accidents, drunken driving etc.

[edit] Practical use

One Laptop per Child program has developed a laptop making use of an IEEE 802.11s based ad hoc wireless mesh networking chip to develop the box. It is the only such device sold to consumers.

In September 2007, the Swedish company TerraNet AB presented a mesh network of mobile phones allowing for the routing of calls and data between participating hand sets, without the need to involve cell sites.[2]
