Invited Talks

CANDAR Keynote 1

  • Chair: Satoshi Fujita (Hiroshima University)
  • Speaker: Xiaohong Jiang (Future University Hakodate)
  • Title: On Capacity Studies for Mobile Ad Hoc Networks (MANETs)
  • Abstract: Mobile ad hoc network (MANET), a flexible peer-to-peer networking technology without pre-existing infrastructure, holds great promises for many critical applications like emergency and battlefield networks, metropolitan mesh networks, and sensor networks. In this talk, I will introduce our recent progress in capacity studies for MANETs with the deterministic MAC protocol, in particular, the capacity studies for such networks under f-cast relay, under power control, under node-probing, under general forwarding, under directional antenna, as well as under any relay routing.

CANDAR Keynote 2

  • Chair: Hiroshi Matsuo (Nagoya Institute of Technology)
  • Speaker: Takayuki Morikawa (Nagoya University)
  • Title: Creating Safe and Sound Cities by Connected Cars
  • Abstract: Car navigation, traffic information provision, and electronic toll collection have been leading the ITS (Intelligent Transport Systems) world for twenty years. Recent advancement in telecommunication technologies can virtually connect vehicles on road networks all the time and provide new services to drivers and societies. This talk introduces the new ITS services with connected vehicles to create safe and sound cities.

WICS Keynote

  • Chair: Toru Nakanishi (Hiroshima University)
  • Speaker: Katsuyuki Takashima (Mitsubishi Electric)
  • Title: Recent Topics on Practical Functional Encryption
  • Abstract: In a traditional public key encryption system, data is encrypted to a particular individual who is fixed by a public key. Functional encryption (FE) gives a new way of sharing encrypted data, and removes this restriction on receivers, where a sender can specify a wide variety of receiver sets, and has fine-grained control over revealed information on encrypted data, under the common public key. Several specific encryption systems fall into this general framework, e.g. identity-based encryption (IBE), inner product encryption (IPE), and attribute-based encryption (ABE), which realize flexible private data sharing. This presentation will introduce the notion of FE, and describe recent progress on security enhancement techniques on FE. The cryptosystems are implemented by using a pairing operation on an elliptic curve, which has achieved many new applications including FE in recent years. I also give a brief summary of the attractive mathematical mechanism, e.g., the algorithm, parameter selection, and underlying security.

AFCA Keynote

  • Chair: Hiroshi Umeo (Osaka Electro-Communication University)
  • Speaker: Maurice Margenstern (Universit√© de Lorraine)
  • Title: A Weakly Universal Cellular Automaton on the Heptagrid with Three States
  • Abstract: In the talk we give a review of the results after thirteen years of research on the topic, from a first universal cellular automaton in the pentagrid with 22 states to a universal cellular automaton in the grid {13,3} with 2 states.

CSA Keynote

  • Chair: Yasuhiko Nakashima (NAIST)
  • Speaker: Fumihiko Hayakawa (Fujitsu Semiconductor Ltd.)
  • Title: ARM based platform SoC for embedded applications
  • Abstract: We developed high performance ARM based platform SoCs which has Cortex-A15, Cortex-A7 and Mali-T624 IPs. Recently open source software is very important issue in embedded system like as Linux, Android, OpenGL, OpenCL and so on. On the other hand, there still are some traditional requirements in their embedded system. In this note, we talk about our platform SoCs balanced between open world and embedded world.

ASON Keynote

  • Chair: Masaki Aida (Tokyo Metropolitan Univ.)
  • Speaker: Masugi Inoue (National Institute of Information and Communications Technology)
  • Title: NerveNet: A Regional-Area Network for Resilient Local Information Sharing and Communications
  • Abstract: NerveNet is a regional-area network providing resilient packet transmission and distributed database applications. It is composed of multiple basestations interconnected with each other by a variety of Ethernet-based wireless/wired transmission systems, configureing a mesh-topological network. It provides not only universal access to the Internet/public telephone network but also regional communications and information sharing in emergency without being connected to the Internet. A large-scale testbed composed of about 30 basestations was deployed and has been operated in two campuses of Tohoku University. A field trial has been carried out in Onagawa town, Miyagi Prefecture.

PDAA Keynote

  • Chair: Akihiro Fujiwara (Kyushu Institute of Technology)
  • Speaker: Koichi Wada (Hosei University)
  • Title: Computational Models for Big Data Processing
  • Abstract: MapReduce feamework has emerged as one of the most widely used parallel computing platforms for processing Big Data on tera- and peta-byte scale. In this talk, we introduce several theoretical computational models for MapReduce from a standpoint of parallel algorithmic power by comparing MapReduce computation with standard parallel computational models such as PRAMs and/or combinational Boolean circuits.

WANC Panel

  • Title: What's wrong with my paper?
  • Chair: Shuichi Ichikawa (Toyohashi University of Technology)
  • Panelists: Koji Nakano (Hiroshima University), Takashi Yokota (Utsunomiya University), Tomoaki Tsumura (Nagoya Institute of Technology)
  • Abstract: There are many papers, which are rejected despite their technical contents. What's wrong with these papers? Three panelists, who have played important roles in academic journals and conferences, give some advices for young researchers to make their papers accepted more easily.
