Fuzzy Multiple Attribute Decision Routing in VANETs

With the wide development of mobile Internet, Vehicular Ad Hoc Networks (VANETs) have attracted more and more research attentions. In this paper, we address the routing issue in the VANETs from a new point of view although there are many outstanding solutions available. Considering a vehicle as a decision maker in the selecting next hop for the transmission from the candidate vehicles, we propose the Fuzzy Multiple Attribute Decision Routing (FMADR) scheme by which we characterize the candidate vehicles with multiple attributes and select the candidates for next hop transmission by the multiple attribute decision making (MADM) approach. Compared with existing routing protocols that utilize one or two specific attributes of VANETs for the next hop selection, the FMADR scheme can boost the message delivery ratio as much as possible. We have carried out simulation to evaluate the performance of the FMADR scheme with the results showing that the proposed FMADR scheme outperforms the existing well-known routing protocols for VANETs.
