Applications of networks to transportsLocalization and Communication for emergency servicesResearch Staff : Jean-Marie Bonnin, Yvon-Marie Le Roux, Patrick Lassudrie-Duchesne, DanielBourreauKeywords : mobile networks, geo-localization, geographical information systemsApplications : ITS, emergency services,Partners & Funding : with partial funding of Région BretagneIntroductionIn case of an accident or a disaster occurringeither on the road, in a factory, in a city, in aharbor or on a boat cruising close to the coast,three points are of the highest importance: therapidity of the intervention of the brigade, theexactness, the completeness and the topicalityof the critical information available at the levelof the headquarter vehicle and the possibilityfor intervening agents to remain in permanentcontact with that vehicle.The LoCoss project (Localisation etCommunication pour les Services de Secours)deals with geo-localization, geographicalinformation systems and wirelesscommunication applied to disaster responsemanagement and coordination. LoCoSS aimsat bringing significant improvements to therescue brigades operations, terrestrial as wellas maritime. The project includes severaldepartments of Pracom (RSM, MO, ELEC) andseveral partners, École Navale, ENSIETA, LCPCNantes, Véhipôle Saint Brieuc. It is a 3-yearproject, which is funded by Region Bretagneand which started on April 2006.trace their movements from the vehicle and tooptimize operations management and thesecurity of the persons. Since all pieces ofequipment (in vehicles and on members of theteam) will be provided with a full IPv6connectivity, the commanding vehicle or theheadquarter will be allowed to directly requestinformation from them.We made an in-depth study of the needsexpressed by the rescue services that areinvolved in the project as client of the solutionsand as experimenters. We identified severalpoints that have to be developed in order toimprove the viability of such a solution forcritical missions. One of the strongrequirements is the ability to give a priority tothe flows depending on the relative importanceof the data exchanged. It is also necessary toincrease the availably of the network service,when one vehicle is out of range for all accessnetworks, it is needed to provide it with IPconnectivity through another truck acting as arelay.Networks aspectsThe RSM team is involved in the networkingaspect of this project. Many wirelesscommunication technologies standards (GPRS,Wi-Fi, WiMAX, DSRC, UMTS…) could be usedto offer a permanent IPv6 connectivity toonboard equipments through NEMOtechnology (Network mobility) and adequateinterface selection mechanism. Therefore, thecommanding vehicle is able to downloadcontinuously the necessary information into itslocal database, before the departure, during itstravel and during the operation. Wirelessduplex links will also be established betweenthe vehicle and some members of the teamequipped with a positioning pack, in order to62 Pracom’s Annual Report 2008
