Delay/Disruption Tolerant Networking (DTN)
Delay/Disruption Tolerant Networking (DTN) is a computer network architecture concept that seeks to accommodate the technical issues in heterogeneous networks that may lack continuous network connectivity or be subject to long delays between and within sub-network systems: situations that may occur because of the limits of wireless radio range, sparseness of mobile nodes, energy resources, intentional interference, and noise. As such DTNs are usually associated with the mobility and limited power of evolving wireless communication devices.

DTN concepts can be applied not only to radio frequency but also ultra-wide band (UWB), free-space optical and acoustic (sonar or ultrasonic) technologies. Examples of such networks include those operating in mobile or extreme terrestrial environments (e.g. military operations in hostile environments), or planned interplanetary networks in space (i.e. internet in space).
TEKEVER CS considers DTN-based concepts as an important technology in future networking especially in specific terrestrial wireless or space-related applications which are known domains of activity of the TEKEVER enterprise Group. TEKEVER CS is especially interested in researching technology that can be applied to network domains constricted by factors like intermittent connectivity, long or variable delays, asymmetric data rates and/or high error rates and is actively working on DTN protocol stacks implementation.
