Keynote title: Redefining Routing and Channel Access in Ad Hoc Networks
Jack Baskin School of Engineering - Computer Engineering Dept.
University of California at Santa Cruz
There has been considerable work on the architecture and protocols of wireless networks since the inception of the ALOHA system and the DARPA packet radio network approximately 40 years ago. However, the design choices that have been made for wireless networks are derivatives of protocols designed for wireline networks and are such that: (a) channel access is either very inefficient and unable to support multimedia traffic across multiple hops, or requires complex clock synchronization to support scheduling schemes based on time division of the channel and dynamic channel reuse; (b) the routes established in wireless networks have no correlation to the transmission schedules used over the wireless links forming those routes, which reduces the efficiency with which flows can be forwarded; and (c) the mechanisms used for information dissemination in wireless ad hoc networks do not scale with the size or dynamics of the network.
In this talk, I argue that the way in which naming, addressing, routing and channel access are done in wireless networks must be redefined from the ground up in order for these networks to scale and perform much more efficiently than they currently do. This redesign must take into account the facts that: (a) nodes do not attach to the network at static points and need not be grouped in stable sets; (b) wireless links do not operate in isolation from one another; (c) establishing transmission schedules and routes are intimately related to one another; (d) SSooding must be eliminated in the signaling of routing protocols; and (e) routing and channel access protocols do not have to use static identifiers that have no relationship to their operation.
I summarize recent results on automatic incremental routing (AIR) and harmonic channel access, which follow the above design guidelines. AIR attains efficient routing in large networks without the use of traditional routing tables or flooding, and supports unicast and multicast routing using the same signaling. Harmonic channel access attains distributed transmission schedules based on circular permutations of identifiers of those entities competing for the shared channel, which need not be node identifiers.

Keynote title: Living in the WAM Continuum: Unified Design and Operation of Wireless and Mobile Networks
Prof. Mostafa H. Ammar
School of Computer Science
Georgia Institute of Technology
Until recently, the vast majority of research in wireless and mobile networks focused on so-called Mobile Ad Hoc Networks (MANETs), where relatively stable end-to-end paths are the norm. More recently, research has focused on a different, Intermittently Connected Network (ICN) paradigm, where stable end-to-end paths are the exception and intermediate nodes may store data while waiting for transfer opportunities towards the destination. Protocols developed for MANETs generally do not work in ICNs since the connectivity assumptions are so different. In this talk I will first give an overview of ICNs and the types of challenges involved in their design and operation. I will then discuss our work in the WAM (wireless and mobile) Continuum project which is based on the simple but powerful observation that MANETs and ICNs fit into a continuum that generalizes these two previously distinct categories. Building on this observation, our work develops a framework that goes further to scope the entire space of wireless and mobile networks. I will summarize two efforts: The first gives clues of the fundamental relationship between ICNs and MANETs by unifying the use of message ferrying in ICNs with the well-known use of connected dominating set-based routing in MANETs. The second effort aims at developing a formal WAM Continuum framework where a network can be characterized by its position in this continuum. Certain network equivalence classes can be defined over subsets of this WAM continuum and this classification can be used to inform network design and operation. I will demonstrate how the unified view enabled by our framework can be used as a systematic, formal descriptive and evaluative tool.

Keynote title: Evaluating Cooperative ITS Applications for Sustainable and Safe Mobility with iTETRIS
Prof. Jerome Härri
Mobile Communication Department
We see today urban traffic growing faster than the capacity of road infrastructures and posing a challenge to traffic safety and to the sustainability of our mobility. In this context, cooperative mobility strategies are expected to become a key enabler for a better usage of the available road infrastructures. Considering the estimation by the Americal Automotive Association of the yearly cost of traffic safety to 160 billion USD, or the yearly cost of traffic congestion to 50 billion EUR by the European Commission, local road authorities are facing a strategic challenge to develop and propose cooperative ITS applications to the public. The question is how can the actual worth of investment and effectiveness of cooperative ITS applications on city road traffic be estimated? To answer this question, new tools capable of providing realistic and large scale assessments and guidelines to road authorities are required. To this aim, we need to define an extensible architecture allowing the interactions of realistic models spanning from wireless communication to traffic and mechanical engineering, and provide a modular integration methodology of cooperative ITS applications. In this talk, we present the outcome of the recently completed work of the European FP7 project iTETRIS during which an open, ETSI standard compliant, and flexible ITS simulation platform has been developped. We describe the modeling challenges, design choices, selected scenarios, and illustrate the benefits and functionalities of the iTETRIS platform through the integration of exemplary key cooperative ITS applications. We further discuss future evolutions, trends, and potential roles of simulations and the iTETRIS platform to reach sustainable and safe mobility resulting in economical, social and ecological wealth improvements.
