any body out there whats is ad hoc network....?

Question

please with diagramatic explanation

Answer 1

FROM WIKIPEDIA

Ad hoc computer network

Main article: Mobile ad-hoc network

In computer networking, ad hoc is a network connection method which is most often associated with wireless devices. The connection is established for the duration of one session and requires no base station. Instead, devices discover others within range to form a network for those computers. Devices may search for target nodes that are out of range by flooding the network with broadcasts that are forwarded by each node. Connections are possible over multiple nodes (multihop ad hoc network). Routing protocols then provide stable connections even if nodes are moving around. Sony's PlayStation Portable uses ad hoc connections for wireless multiplayer gaming, as does the Nintendo DS (although Nintendo does not officially use the term).


FROM SEARCH MOBILE:

ad-hoc network


DEFINITION - An ad-hoc (or "spontaneous") network is a local area network or other small network, especially one with wireless or temporary plug-in connections, in which some of the network devices are part of the network only for the duration of a communications session or, in the case of mobile or portable devices, while in some close proximity to the rest of the network. In Latin, ad hoc literally means "for this," further meaning "for this purpose only," and thus usually temporary. The term has been applied to future office or home networks in which new devices can be quickly added, using, for example, the proposed Bluetooth technology in which devices communicate with the computer and perhaps other devices using wireless transmission.

One vendor offers an ad-hoc network technology that allows people to come to a conference room and, using infrared transmission or radio frequency (RF) wireless signals, join their notebook computers with other conferees to a local network with shared data and printing resources. Each user has a unique network address that is immediately recognized as part of the network. The technology would also include remote users and hybrid wireless/wire connections.

Jini is an approach to instant recognition of new devices in a network that would seem to make it easier to have an ad-hoc network.


See IEEE 802.11, Bluetooth, or ultra-wide band. The alternative is infrastructure, with a base station that manages the network for its range. The theory behind ad hoc networks falls within the Distributed Transient Network-paradigm.

The term ad hoc network can also refer to an independent basic service set (IBSS).
