摘要

Many routing protocols have been designed for mobile ad hoc networks. However, those existing solutions assume an end-to-end path established from a source to a destination. Some ad hoc network scenarios are characterized by intermittent connectivity and frequent topology changes. Therefore, disruption tolerant network (DTN) technologies are proposed to cope with these scenarios. Many routing protocols have been proposed for DTNs used for delivering messages within the same administrative domain. However, in real life scenarios, multiple groups may desire to communicate with one another. Thus, interdomain routing protocols need to be designed to deliver interdomain traffic.;In this thesis, we describe how we design experiments using the ORBIT testbed to evaluate the Gateway Based Interdomain Routing (GBIR) protocol. We also study the message delivery performance of GBIR in a large scale network by emulating node mobility using traces generated by the reference point group mobility (RPGM) model generator. Specifically, we study how message sizes and the choice of intradomain routing scheme affects the end-to-end message delivery latency as well as the successful delivery ratio. In addition, we study the impact of node speed on the delivery performance. Our evaluations show that GBIR achieves high delivery ratio and low end-to-end delivery latency for the interdomain traffic. Smaller E2E delivery latency is observed when nodes move faster (but not to the extent of causing too much link disruptions). In addition, smaller intradomain delay is observed when a domain runs the PROPHET scheme rather than the RAPID scheme.
