Partially decentralised wireless routing for distributed augmented reality applications

Mobile communication can in general be divided into two categories. Centralised mobile communication interfaces the mobile terminals through base stations that are connected to a fixed network. A good example of a centralised mobile system is GSM. Decentralised mobile communication does not have the concept of a base station but the messages are relayed towards their destinations through other mobile terminals. This kind of approach has been considered, for example, in disaster information systems that cannot rely on the fixed infrastructures. This paper presents one routing solution to a wireless low-power picocell network where the flexibility of decentralised communication systems is required, together with the good connectivity brought by centralised and authorised networks. These features are applied in order to provide flexible communication between augmented reality services embedded to electromechanical products and the users wearing light weight virtual reality user interfaces. A routing mechanism that quickly adapts itself with low overhead is a key factor for the success of such an environment.
