Research within Delay- and Disruption Tolerant Networks (DTN) has evolved into a mature research area. PRoPHET is a routing protocol for DTNs that was developed when DTN research was in its infancy and which has been studied by many. In this paper, the authors investigate how the protocol can evolve to meet a new challenge that has been identified through research and practical experience. They propose some minor modifications to the routing metric calculations done in PRoPHET which has potential to alleviate some issues and improve the performance of the protocol. Using these modifications, they define an updated version of the protocol called PRoPHETv2.
