Vehicular networks and applications: Challenges, requirements and service opportunities

Autonomic Cooperative Networking for Vehicular Communications

“…Finally, while these DEs are located at autonomic cooperative nodes, it is still necessary to provide substantial coordination at the network level. This task is accomplished by the Cooperative Routing decision element CR DE which is responsible for overseeing the situation from a higher level perspective and orchestrating the concurrent cooperative and non-cooperative transmissions among vehicles [13], [12].…”

“…In particular, to accommodate the routing information enhanced cooperative transmission, a specific architectural extension depicted in Figure 6 is necessary as a component aligned with the rationale behind the Generic Autonomic Network Architecture (GANA) [4]. Autonomic networking has emerged as one of the most promising approaches towards the instantiation of the self-managing future networked systems [4] such as vehicular communications [13], [12]. Autonomicity is defined as the ability to self-configure without a need for any external intervention, while the flavour of a system being autonomous means its ability to display certain dose of cognition.…”

“…This paper outlines the evolution of the technologies leading to the instantiation of autonomic cooperative networking for vehicular systems [13], [12]. The discussion covers not only spatio-temporal transmission and its successful transition into cooperative relaying but also puts emphasis on the very important role of network layer routines eventually enhanced with the concept of autonomic system design.…”

“…Last but not least, the system needs to be stable and scalable, and so largescale vehicular networks should implement the notion of self-management [4]. A future vehicular network may be actually even expected to somewhat imitate the behavior of a living organism meaning it should be capable of functioning by itself without any necessity for a specific external human intervention during most of the time of operation [13], [12]. Such autonomic network architectures are currently being developed with the aid of the concept of decision elements and control loops and are being pushed onto the standardisation path [3].…”
