Conclusion and next steps

ConclusionConclusionConclusionConclusion

� A novel E2E IPv6 architecture deployed in ITS networks is a future proof ITS architecture for

on going deployments :

– a very efficient solution to optimize overhead since the double stack avoids mounting

of useless tunnels (reduced encapsulation impact)

– very good overall performances achieved in terms of delay, throughput (real capacity of

the communication links) and handover

� Combination of heterogeneous networks complementarities and IP mobility management to

enable efficient ITS communications delivering service continuity to vehicular customers


enable efficient ITS communications delivering service continuity to vehicular customers

� E2E network cooperation architecture will support the delivery of full fledge of ITS services,

road safety, traffic efficiency and mobility/comfort thanks to extended coverage and improved

capacity and delay

� Operation of V2V and V2I communications to create new opportunities of cooperative

services

Next stepsNext stepsNext stepsNext steps

� Deployment and experimentation of an eMBMS architecture on top LTE network to

demonstrate unicast and broadcast applications across ITS G5 and LTE communication links
