Resilient Shell-Based Networking Frameworks for DTN Environments: Enhancing Reliability and Security across Disrupted and High-Latency Satellite Channels
Abstract: The foundation of DTN, as suggested by the Internet Research Task Force (IRTF), is the definition of a suite of protocols that function in networks with periodic disconnections and long- duration route conditions. A permanent end-to-end channel from the source to the destination is the foundation of traditional IP-based networking. However, DTN employs a store-carry- forward approach that gives intermediary nodes the ability to temporarily hold messages (or bundles) until …
