Dynamic Source Routing In Mobile Ad Hoc Network Protocol Dsr Test Bed

Under the background of rapid development for both wireless communication technology and computer networks, Mobile Ad hoc Network - MANET, attracts people's extensive attention. MANET is actually an autonomous system composed of serial nodes which can communicate with each other through multi-hops in mobile wireless environment. MANET has some inherent characters like frequently changed topology, limited link layer bandwidth and constrained resources for computation and storage. But since it can be working without any infrastructure, it is supposed to play a big role in lots of environments such as military battle and emergency assistance.Researches on MANET are actually extensive and comprehensive, and during all of these, MANET routing protocol is obviously the most important one, because efficient packets delivery need efficient routing protocol first. One of the typical representations in various MANET routing protocols is just Dynamic Routing Protocol– DSR, which is always treated as a simple but highly efficient reactive MANET routing protocol. Based on the study of related RFC, DSR performance optimization and security expanding were discussed. And then, based on a deep study and research on DSR virtual model supplied by OPNET and its uniform MANET manger architecture, we kept focus on DSR test-bed in real-world environment. Strategies about embedding DSR into Windows NDIS architecture were discussed first. And then, a detailed analysis for PASSTHRU, the classical NDIS intermediate driver example, was given. Based on the work all above, we pre-analyzed several key problems about creating the real-world DSR protocol stack, and proposed concrete designs of this protocol stack's data structures and basic process flows. In the end, experimental results in laboratory environment proved stack's availability.
