A Testbed for Evaluating Delay Tolerant Network Protocol Implementations
2008 (English)In: Proceedings 5th Swedish National Computer Networking Workshop, 2008Conference paper (Refereed)
We present our delay tolerant network testbed and methodology, for testing opportunistic networking protocols and applications, without having to modify the software. To support multiple operating systems running on a single physical computer, virtual machines are at the core of the testbed. Scripted communication opportunities are used to model connectivity in the network. A set of benchmark connectivity models are available to perform evaluations with predictable protocol behavior; dynamic topologies from real-world traces are also supported. Using this environment, we evaluate the testbed with a delay tolerant application and compare the outcome to that of a real-world experiment. Finally, we discuss our results and the limitations of the testbed.
