A performance comparison of DTN bundle protocol implementations on resource constrained nodes

As delay-tolerant networking (DTN) finds applications in a wider variety of environments, DTN implementations have been ported to a variety of devices. Performance testing of DTN implementations has typically been carried out on powerful hardware, but there have been few performance evaluations on resource-constrained devices. We present the results of experiments comparing two of the major open-source DTN implementations, DTN2 and IBR-DTN, on resource-constrained nodes. The comparison is in terms of storage and receive performance, as well as network throughput.
