Ad Hoc Networks In Mobile Computing

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.

Ad hoc networks in mobile computing.

Ad hoc networks are mostly wireless local area networks lans. 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 devices communicate with each other directly instead of relying on a base station or access points as in wireless lans for data transfer co ordination.

They consist of set of mobile nodes connected wirelessly in a self configured self healing network without having a fixed infrastructure. The network uses a network layer routing protocol to link mobile nodes and establish routes distributedly and automatically. 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. 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.

The term ad hoc is a latin word that literally means for this implying improvised or impromptu. Nodes typically transmit in broadcast messages that reach only nearby nodes.
