Accelerated service discovery in vehicular networks

Abstract

Service discovery in vehicular networks has been extensively investigated in literature. Collecting and disseminating data in high mobility networks in a reliable and efficient way without exhausting network bandwidth is still challenging, due to unreliable channel access in broadcast scenarios and thus results in loss of time through resending packets. Sending delta information to reduce network traffic, grouping vehicles of same direction and velocity into clusters, performing multiplexing to access the shared wireless network channel are interesting existing approaches in vehicular networks. Discovery protocols do not profit from a combination of those techniques yet. This paper proposes the High Mobility Gossip-Konark for high mobility vehicular networks. Simulations underline the proposed design.
