Vehicular Ad Hoc Network (VANET) is a recently developed technology to achieve traffic safety and efficiency purposes through inter-vehicle communications, where the routing protocols in VANETs play a very important role. However, one that fits all kinds of scenarios and applications does not exist for now. Insufficient forwarding nodes and network congestion can both bring severe degradation to the performance of routing protocols in VANETs. In this paper, we propose an adaptive strategy based on the combination of these two situation and then apply this strategy to Location-Aided Routing (LAR) protocol to keep the routing performance from degradation. In the adaptive strategy we use the Multiple Attribute Decision Making (MADM) to establish the control function which can accommodate message transmission to the circumstances dynamically. Theoretical analysis and simulation performance prove that this strategy can improve the packet delivery ratio (PDR) of LAR protocol effectively.
