| Notes | multi-radio ; VANET ; graph coloring ; channel feedback ; dynamic spectrum allocation Sun Zhile, Li Demin , Tao Bing, Liu Xiao （School of Information Science ＆ Technology,Donghua University ,Shanghai 201620 ,China; Engineering Research Center of Digitized Textile ＆ Fashion Technology, Ministry of Education Donghua University Shanghai 201620, China） In order to achieve dynamic allocation of communication spectrums between the vehicle nodes in muhi-radio VANET, a dynamic spectrum allocation algorithm based on channel feedback is proposed. This paper analyzed the quality of channel, defined channel feedback matrix. The vehicle nodes could select available channel according to the values in channel feedback matrix. So as to realize the maximization of channel utilization.Through software simulation, it can be seen that this algorithm reduces time overhead significantly under the precondition of the maximize system total revenue and significantly improves the network performance of muhi-radio multi channel VANET. 11- |
