| Abstract |
|
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. |
| About the speaker |
 Roch H. Glitho [SM] holds a Ph.D. (Tekn. Dr.) in tele-informatics (Royal Institute of Technology, Stockholm, Sweden), and M.Sc. degrees in business economics (University of Grenoble, France), pure mathematics (University Geneva, Switzerland), and computer science (University of Geneva). He works in Montreal, Canada as associate professor at ETS, University of Quebec, and as adjunct associate professor at CIISE, Concordia University. In the past he has worked in industry for around a quarter of a century and has held several senior technical positions at LM Ericsson in Sweden and Canada (e.g. expert, principal engineer, senior specialist). His industrial experience includes research, international standards setting (e.g. contributions to ITU-T, ETSI, TMF, ANSI, TIA, and 3GPP), product management, project management, systems engineering and software/firmware design. He is a member of several editorial boards including IEEE Network and IEEE Communications Surveys and Tutorials. In the past he has served as IEEE distinguished lecturer, Editor-In-Chief of IEEE Communications Magazine and Editor-In-Chief of IEEE Communications Surveys & Tutorials. His research areas include architectures for end-users services, distributed systems, non conventional networking, and networking technologies for emerging economies. In these areas, he has authored more than 100 peer-reviewed papers, more than 30 of which have been published in refereed journals. He also has more than 20 granted patents in the aforementioned areas. |
