Unconventional Network or Challenged Network

Today, I attended the talk delivered by Dr Roch Glitho at Telecom SudParis. His talk was mainly about the unconventional network (Solar network, wireless sensor network and MANET) that forced to shrink the five layers TCP/IP stack into three layers such as Application, Middleware (Routing and transport) and telecommunication layer (MAC and phy).

He presented two middlewares such as IETF delay/disruption tolerant network (DTN) bundle overlay and the EU 6FP ambient control space (ACS) overlay. Application developer should know about these overlays for developing the services in addition to the business logic. Moreover, interconnections of different overlays will pose big hurdle for user experience.
