“…Nevertheless, in situations where nodes move faster or more frequently, or die because of battery shortage, maintenance mechanisms are needed for the tree-based topology. We plan to leverage work on tree maintenance in MANETs to develop such mechanisms [13].…”

“…But again CBR requires a one-tree structure network topology [25], almost impossible to maintain when the size of the network increases. The high mobility of nodes in the network may make this tree maintenance issue even worse since a tree may become partitioned into a number of trees leading to serious issues finding a path to merge those trees.…”

Abstract. The past decade has witnessed the emergence of Vehicular Ad-hoc Networks (VANET), specializing from the well-known Mobile Ad Hoc Networks (MANET) to Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) wireless communications. While the original motivation for Vehicular Networks was to promote traffic safety, recently it has become increasingly obvious that Vehicular Networks open new vistas for Internet access, providing weather or road condition, parking availability, distributed gaming, and advertisement. In previous papers [27,28], we introduced Cooperation as a Service (CaaS); a new service-oriented solution which enables improved and new services for the road users and an optimized use of the road network through vehicle's cooperation and vehicle-to-vehicle communications. The current paper is an extension of the first ones; it describes an improved version of CaaS and provides its full implementation details and simulation results. CaaS structures the network into clusters, and uses Content Based Routing (CBR) for intra-cluster communications and DTN (Delay -and disruption-Tolerant Network) routing for inter-cluster communications. To show the feasibility of our approach, we implemented and tested CaaS using Opnet modeler software package. Simulation results prove the correctness of our protocol and indicate that CaaS achieves higher performance as compared to an Epidemic approach.

“…In fact, other research works in MANET middleware already followed this approach. In [9] authors present COMAN, a protocol to organize the nodes of a MANET in a tree-shaped network providing content-based routing functionalities. COMAN is implemented at the application layer and it benefits from topology information to self-repair and reconfigure the middleware.…”

We believe that any MANET middleware should be aware of the underlying multi-hop routing protocol to improve communication efficiency. In general, existing MANET middleware either ignore the underlying routing protocol or create specific cross-layer solutions that break the strict layering of the network stack. This problem is even more severe in the case of traditional group communication middleware (GC) where membership protocols, failure detection mechanisms or flow control layers can considerably harm the overall performance of the network.We propose to move the routing logic to the application layer in order to achieve a smooth and clean integration between the middleware and the underlying MANET topology.In this line, we have modified a well-known GC toolkit (JGroups) in order to adapt membership protocols, failure detectors and flow control mechanisms to the underlying MANET topology. We have implemented the MANET OLSR protocol in the application layer using UDP (jOLSR). On top of it, we have developed an overlay Multicast protocol (OMOLSR) that directly benefits from the OLSR protocol to improve communication efficiency. As a consequence, in our middleware group membership is obtained from OMOLSR, failure detection from the jOLSR protocol, and our modified flow control protocol benefits from jOLSR topology information. We validate our approach in a real test-bed to demonstrate the feasibility and efficiency of our middleware.
