bundule aggregation process in dtn

ion-dtn/tutorial.html at master · NASAHackTO/ion-dtn · GitHub

< li > The ion package, which implements the DTN Bundle Protocol (BP), has been: upgraded to conform to BP version 5, submitted to IETF in December 2006. The changes are almost exclusively internal to the software and protocol: the format of bundles exchanged through the delay-tolerant network is altered, but the API for ION is mostly unchanged.

Role of Bundle Sheath Extensions and Life Form in Stomatal ...

Abstract. Bundle sheath extensions (BSEs) are key features of leaf structure with currently little-understood functions. To test the hypothesis that BSEs reduce the hydraulic resistance from the bundle sheath to the epidermis (r be) and thereby accelerate hydropassive stomatal movements, we compared stomatal responses with reduced humidity and leaf excision among 20 species with heterobaric or ...

Intentional Naming in DTN

In the DTN Bundle Protocol, the destination field (of the primary block) is set when the bundle is created and not modified thereafter because the Bundle Security Protocol requires that the contents of the primary block not be changed en-route; otherwise, the bundle will fail end-to-end authentication checks.

Delay Tolerant Networks

Delay tolerant networks are a research subject on their own; however, they are quite important in many of challenges related to energy efficiency and green communication. Since many of the networks are power constrained, rely on batteries, and often involve mobility, there is a high chance that at some point the network will become partitioned.
