them into account to manage the multipleinterfaces and to route flows.RealizationThe team is mainly involved in this project inorder to study and design the relation betweenmobile routers and applications running onnodes attached to the mobile network. It isalso in charge to develop the multipleinterfaces and policies management systemson the mobile router.Last year, a second version of thespecifications have been issued. They coverthe global architecture specification, themultiple interfaces management at the mobilerouter and the protocols used to announcenetwork characteristics to the applications orto declare application needs to the mobilerouter. The API used by the applications todialogue with the local connectivity managerand then with the mobile router has also beendefined.The development of the policies managementin the mobile router is on the way. The firstversion of the POLicy handler for Nemo,Application REsponsiveness and Fun(POLNAREF) has been provided to partners. Itis responsible for making flow by flow routingdecisions based on the environmentsurrounding the mobile router (NetworkAvailability, Speed, Time of the day...), as wellas predefined rules given by the administratoror the network operator.The Flow Protocol, which is the piece ofsoftware that will enable applications to adaptto the mobile network’s environment, is nowready to be integrated in POLNAREF and in themobile nodes.Future WorkIn the next steps our work will be integratedwith the components provided by the otherpartners.A final step would be the settlement of ademonstration testbed on which severalexperiments will be achieved in order toevaluate our global architecture and tocompare it with existing proposals.ConclusionThe new solutions defined by the REMORAproject will be actively supported andpromoted by each partner in the ad'hocstandardization bodies. REMORA will also relyon the close relationship between some of itsmembers and the WIDE Japanese consortium,especially the NAUTILUS6 working groupwhose R&D activities focus on standardizingNEMO mechanisms and testing them. REMORAachievement will provide input to improve theCALM standard (ISO TC204 WG16). It couldhelp with two of the main challenges faced bythis on going standard. The distribution thedecision process between embarked devicesand OBU (On Board Unit) is one of them.Another one stands in the way to exchangeinformation between layers through themanagement plane as well as between entitiesinside the vehicle.The results of the project will lead to newapproaches for a new generation mobileInternet. And those will allow mobile users tobenefit from services that are morepersonalized. Thanks to its federative aninnovative aspects, REMORA is reallyinteresting for both the French academic andtelecom industry communities. REMORA willalso contribute to promote the IPv6deployment and the creation of new servicesassociating information, entertainment andtelecommunications.References[1] Ernst, Thierry, “The InformationTechnology Era of the Vehicular Industry”,ACM SIGCOMM Computer CommunicationReview (CCR) Volume 36, Issue 2, April 2006.[2] V.
