摘要：The mobile nodes perceive the real-time routing information of different sections, and analyze the reliability of the movement direction of nodes, data exchange, and transmission delay and path failure. By combining movement direction, speed and locations, the routing path is adaptively updated according to the network states of the sections so as to achieve effective message delivery. In this paper, a real-time information oriented service-aware routing algorithm (RTIA) is proposed. The transmission mode of the RTIA is no copy, real-time information oriented, and service aware, which can effectively improve the message delivery rate and reduce delay. The simulation results prove the superiority of the RTIA algorithm. the merchant can trace the traitors from a pirated copy by means of the embedded unique fingerprint, while the customer is immune of being framed due to the asymmetric property. First, multicast that is an efficient transport technology for one-to-many communication is exploited, which can reduce the bandwidth usage significantly. Second, symmetric encryption instead of public-key encryption is performed on the multimedia content, which can reduce the complexity and communication cost.
