Adaptive Topology Based Gossiping in VANETs Using Position Information

Abstract. Gossiping is a lightweight and simple technique for information dissemination in many application domains, be it in Wireless Sensor Networks (WSNs), Mobile Ad-hoc Networks (MANETs), or Vehicular Ad-hoc Networks (VANETs). Much research has been conducted in the past on probabilistic dissemination methods because of their efficiency compared with simple flooding and their simple application. However most work was focused on static gossiping, i.e., the gossiping probability cannot be adapted according to topology changes. Thus, topology characteristics have to be known in advance. In this work the use of position information for building up a neighborhood relationship is proposed. Based on this information, a forwarding hierarchy is constructed and the protocol is capable to adjust the dissemination probability dynamically in a distributed manner. The protocol is evaluated in a highway scenario, where the network characteristic varies from sparse networks with highly mobile nod...
