Abstract: Taking the characteristics of VANET(vehicular ad-hoc network) into account, a DTN (delay-tolerant networks) routing algorithm called motion-aware spray and search router (motion-aware spray and seek, MASS) was proposed based upon spray and wait router optimization design, and the method of optimization and specific procedures of the algorithm were described. Subsequently, several classic DTN routers and MASS router were simulated on ONE platform. Comparing the routing algorithms by picturing the statistics mentioned above, the different performance of each router on the VANET was analyzed. Finally, the effectiveness and reliability of the MASS router was proved.
