Survey on context-aware publish/subscribe systems for VANET

Abstract : The publish / subscribe scheme is an efficient paradigm for communication widely used in wired networks. However the use of this paradigm in the context of mobile networks such as VANETs is still an open research topic. In particular, the communication needs of mobile nodes often depend on the node state, location and/or surroundings. Consequently, extensions to the P/S paradigm have been proposed that introduce the concept of node context. This paper propose a survey on these context-aware publish / subscribe solutions for VANETs. We will particularly focus our discussion on two example applications drawn from the context of civil aviation and will argue that Aeronautical Ad hoc Networks (AANETs) are a subgroup of VANETs.
