S-38.3155 Challenged Networks


This seminar addresses communications in networking environments with unusual characteristics, i.e. properties that traditional design of communication protocols has not taken into account. Such "challenged networks" may exhibit, e.g., long communication delays, unpredictable link availability, and may not even provide an end-to-end path at all. These characteristics are partly inherent to certain link layer technologies (e.g. transmission error rate in wireless networks), but mostly stem from specific communication settings and system architectures (e.g. sensor networks connecting underwater equipment or planetary orbits). We will analyze numerous challenged networking environments and their communication characteristics. We will look at novel networking architectures dealing with such specific environments and investigate routing, service, and application aspects of delay-tolerant networking.
