The OCARI (Optimization of Ad hoc Communications in Industrial networks) project, funded by ANR, started in February 2007. It has a duration of 36 months. The industrial partners are EDF (coordinator), DCN and One-RF. The academic partners are LIMOS (Clermont Ferrand university), LATTIS (Toulouse university), LRI (Paris Sud university) and INRIA.

The OCARI project deals with wireless sensor networks in an industrial environment. It aims at responding to the following requirements which are particularly important in power generation industry and in warship construction and maintenance:

The development of OCARI targets the following industrial applications:

To meet the requirements of supported applications (remote command of actuators, tele-diagnostic...), new solutions will be brought to manage several communication modes, ranging from deterministic data transfers to delay tolerant transfers. A key issue is how to adapt routing algorithms to the industrial environment, taking into account more particularly limited network resources (e.g.; bandwidth), node mobility and hostile environment reducing radio range.

The OCARI project aims at developing a wireless sensor communication module, based on IEEE 802.15.4 PHY layer and supporting EDDL and HART application layer. The INRIA contribution concerns more particularly energy efficient routing and node activity scheduling.

Moreover, INRIA has specified the network layer implementing EOLSR and SERENA. INRIA has defined the message format as well as the network primitives offered to the application layer and management entity. Furthermore, primitives between the network and MAC layers have been specified in cooperation with LIMOS.
