摘要
为了高效地使用有限的网络资源,提出1种基于可信时空协议(TSTP)的地理路由协议。以距离和剩余生存时间(TTL)等面向地理位置的参数作为路由度量,并映射到传输时间偏移量中,进而评估不同度量组合的影响。以节约资源的方式提供经认证、加密、定时和参考地理位置的数据消息。仿真结果表明,在不同场景下,TSTP协议的端到端时延、公平性、传输比率等指标都取得较好效果。
A geographical routing protocol based on trustful space-time protocol(TSTP)is proposed to use the network resources efficiently.The distance and time to live(TTL)are used as routing metrics,and the spatial distortion algorithm is introduced to map any metric to a transmission time offset and evaluate the influence of different metric combinations.Authenticated,encrypted,timed,and geo-referenced messages are provided in a resource-efficient way.Simulation results show the end to end delay,fairness and transmission ratio of TSTP present good performance in a series of network scene.
