Delay Tolerant Networks

Definition

Delay Tolerant Networks are computer networks designed to operate effectively despite frequent disconnections and long transmission delays. These networks utilize a “store-carry-forward” approach, where data is held by intermediate nodes until a connection to the next hop is established. They are engineered to function in environments lacking continuous end-to-end network paths, such as interplanetary communication or remote sensor deployments. This architecture prioritizes eventual delivery over real-time connectivity.
