There are several assumptions underlying conventional network architectures as epitomized by the Internet TCP/IP network architecture (e.g. low error rate, symmetric bidirectional rates, bidirectional end to end path). However, more and more networks that do not meet these assumptions are being deployed (e.g. deep space networks, mobile ad hoc networks and wireless sensor networks). They are known as challenged (or unusual, or non conventional) networks. This speech focuses on applications enablers for challenged networks. We propose a three dimensional taxonomy (challenged network type, application type, protocol stack levels) and use it as backbone in the presentation. The most widely deployed challenged networks are briefly reviewed. Challenged networks-agnostic application enablers (i.e. enablers that target all challenged networks) such as the IETF delay/disruption tolerant network (DTN) bundle overlay and the EU 6FP ambient control space (ACS) overlay are discussed. Challenged network specific enablers (i.e. enablers that target a specific challenged network) are introduced, using multiparty session enablers for mobile ad hoc networks and middleware for wireless sensor networks as concrete examples. Research challenges are identified throughout the speech.
