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.
Biography: Roch H. Glitho [SM] (http://www.ece.concordia.ca/~glitho/) 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.
