Ad hoc network
The networks Ad hoc (in Latin: “which goes towards it towards what it must go”, i.e. “formed with a precise aim”, such as a ad hoc commission , formed to regulate a particular problem) is wireless networkings able to be organized without infrastructure defined beforehand.
The ad hoc networks, in their mobile configuration, are known under the name of MANet (for Mobile Ad hoc NETworks ).
Detailed description
Each entity ( node ) communicates directly with its neighbor. To communicate with other entities, it is necessary for him to make pass its data by others which will be given the responsability to convey them. For that, it is initially paramount that the entities are the ones compared to the others, and are able to build roads between them: it is the role of the protocol of routing.Thus, the operation of an ad hoc network notably differentiates it from a network like the network GSM, the networks Wi-Fi with access points: where one or more basic stations are necessary to the majority of the communications between the various nodes of the network ( mode Infrastructure ), the ad hoc networks organize them-even and each entity can play various parts.
The simplest use and most current of the ad hoc networks is made by the wireless networkings Wi-Fi by allowing a fast installation of a connection network between two computers.
