Ad Hoc Networks In Mobile Computing

A mobile ad hoc network manet is a collection of mobile nodes that act as both routers and hosts in an ad hoc wireless network and that dynamically self organize in a wireless network without using any pre established infrastructure.

Ad hoc networks in mobile computing.

Manet nodes are free to move randomly as the network topology changes frequently. Ad hoc networks are mostly wireless local area networks lans. They consist of set of mobile nodes connected wirelessly in a self configured self healing network without having a fixed infrastructure. A mobile ad hoc network manet is generally defined as a network that has many free or autonomous nodes often composed of mobile devices or other mobile pieces that can arrange themselves in various ways and operate without strict top down network administration.

Each node behaves as a router as they forward traffic to other specified node in. A mobile ad hoc network manet involves mobile devices communicating directly with one another. The network uses a network layer routing protocol to link mobile nodes and establish routes distributedly and automatically. Nodes typically transmit in broadcast messages that reach only nearby nodes.

A manet is a network of wireless mobile devices without an infrastructure that are self organizing and self configuring and is sometimes referred to as an on the fly or spontaneous network. The term ad hoc is a latin word that literally means for this implying improvised or impromptu.
