Ad Hoc Networks In Mobile Computing

Ad hoc networks are mostly wireless local area networks lans.
Ad hoc networks in mobile computing. Manet nodes are free to move randomly as the network topology changes frequently. They consist of set of mobile nodes connected wirelessly in a self configured self healing network without having a fixed infrastructure. Nodes typically transmit in broadcast messages that reach only nearby nodes. The term ad hoc is a latin word that literally means for this implying improvised or impromptu.
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. A mobile ad hoc network manet involves mobile devices communicating directly with one another. 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 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.
Manet stands for mobile adhoc network also called as wireless adhoc network or adhoc wireless network that usually has a routable networking environment on top of a link layer ad hoc 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.
