Reliable Geocasting in Vehicular Networks
Description of research
Intelligent Transport System (ITS) applications sometimes require geocast and broadcast messages to be delivered with very high reliability, especially those where vehicle movement depends on the exchanged information. The dynamic nature of Vehicular Networks makes the reliable geocasting and broadcasting of information very challenging. New mechanisms are needed to provide this reliability in a lightweight and scalable way, even in environments where many packet transmissions fail, and where the interconnection topology is rapidly changing due to vehicle movement.
In the research, reliable broadcasting and geocasting mechanisms will be designed and validated. The context of the mechanisms will be IEEE 802.11p-based wireless communication standards and the geonetworking protocols for vehicular networking. Validation will be done by means of simulation, prototyping, and/or analytical methods.
Further, reliable geocasting may be extended from the restricted Vehicular Network scope to an Internet-wide scope. A possible direction of solution here is to extend the concept of DNS with location-based queries, and to combine it with multicast communications, where also multicast groups are geographically defined.

Co-operative ITS Systems for Enhanced Electric Vehicle Mobility Project Number: 314129
A 7th Framework Programme project, Mobility2.0 will develop and test an in-vehicle commuting assistant for FEV mobility, resulting in more reliable and energy-efficient electro-mobility through utilising co-operativesystems to simultaneously consider the main bottlenecks: Range anxiety related to the limited FEV range, scarcity of parking spaces and the congestion of roads, so that such an optimisation can be achieved which guarantees reliable transportation.
Mobility2.0 outcomes will be the following:
· An FEV-specific multi-modal urban guidance application implemented for prolific smart-phone platforms; this application will include the integrated reservation of a suitable FEV recharging spot, while also prioritizing FEVs with low battery levels for the reservation, and making optimal use of the available public transportation along the journey.
· The above application will include the capability to allow municipal/utility control over the temporal and spatial aspects of recharging; the corresponding tools will be dynamic electricity pricing and a map analysis framework.
· The project will specify the scalable broadcasting of FEV recharging spot notification over 5.9 GHz networks and MBMS technology.
· The project will specify and contribute to standardization the technology, which enables plugged-in FEVs to act as 5.9 GHz roadside units, maintaining infrastructure connectivity via the V2G interface.
End-to-end validation of the above results at two test sites.
Besides FEV manufacturing, FEVs may also be produced by the conversion of traditional vehicles into FEVs. Mobility2.0 shall ensure that its results are applicable to both FEV types.
The ‘Mobility2.0’ proposal name is meant to express that the co- operative electromobility technology targeted by this project is a next level concept for personal mobility.
One of the research areas of the DACS group is Vehicular Networking. Vehicular networks allow cars to communicate between themselves and with roadside infrastructure to make road traffic safer, more efficient, and “greener”. Within the Mobility 2.0 project, the DACS group, together with partners from a number of European countries, will develop and test a cooperative commuting assistant for fully electrical vehicles, resulting in more reliable and energy-efficient electro-mobility.
