Contrary to the initial vision of a completely decentralised network, a less general and more pragmatic solution appears by introducing some constraints which simplify the routing problem: fixed terminals, or, if one really wishes to keep a certain mobility, a micro-cellular system in which the infrastructure consists of an Ad-Hoc mesh network, which should largely simplify its deployment, thus keeping this aspect.
The Ad-Hoc network is often presented as a manner of connecting objects in an indoor environment, but a telecommunication operator (either fixed or with mobiles) can use them to deploy his network infrastructure.
