英文摘要： Spatial Information Networks (SINs) have experienced explosive growth in recent years. The SIN is characterized by the highly topologic dynamics, the frequent data link handoff, the larger end-to-end latency and the high bandwidth-delay-product. Also the network shows the characters of high bit error rate and the limited network resources. Aimed at the security routing and efficient transmission requirements in the SINs, this project (1) studies the dynamic behaviors of SIN, including the delay variations, the topological change rates, the link handoff models, and the causes of packet losses to model the dynamic behavior of SINs; (2) investigates the routing protocol to support the requirement of different services; (3) explores the key causes which affect the transmission efficiency, provides the improved and newly designed efficient transmission protocols for the upper layer SIN traffic; finally (4) the simulation platform is developed to evaluate the availability and performance of the proposed mechanisms and algorithms. With our work, the project will explore new ideas and methods for the design of routing and reliable transmission control protocol for SINs. It will not only provide a theoretical guidance for further explorations of routing and reliable transmission protocol for SINs, but also provide techn
