Routing Protocols for Vehicular Ad Hoc Networks in Rural Areas
Source: Montana State University
Research on vehicular ad hoc networks (VANETs) has focused mainly on efficient routing protocol design under conditions where there are relatively large numbers of closely spaced vehicles. These routing protocols are designed principally for urban areas with high node density, fully connected networks, and are not suitable for packet delivery in a sparse, partially connected VANET. In this paper, authors examine the challenges of VANETs in sparse network conditions, review alternatives including epidemic routing and propose a Border node Based Routing (BBR) protocol for partially connected VANETs. The BBR protocol can tolerate network partition due to low node density and high node mobility.
