Special Session on «Software-Defined Networking»
Software-defined-networking (SDN) in general describes the provision of programmable interfaces within the network and its substrates to enable a high degree of flexibility in adapting to new application requirements and network capabilities. This requires some methods to interact between data-plane and control-plane. One method, among others, is OpenFlow which is often mixed up with SDN. The typical SDN elements are the forwarding functions in network devices, network controllers and finally applications.
Special Session on «Underwater Acoustic Communications»
During the last two decades, significant achievements have been made in the development of underwater acoustic communication systems. These systems will offer a wide array of applications ranging from providing early warningsfor natural disasters, remote control of offshore oil and gas platforms over the discovery of new resources up to the mapping of the ocean bottom for detection of objectsor for building subsea structures.Many of the applications under development involve not only point-to-point links, but also network configurations enabling real-time communications with swarms of autonomous underwater vehicles and submarines. Emerging underwater acoustic networks will consist of both stationary and mobile nodes. They are located on underwater vehicles and robots, which are equipped with sensors, sonars, and underwater video cameras. An onshore system operator will be able to get access to the underwater acoustic network via a wireless link to a central node that is placed on a surface station. The challenge of the network is to manage the exchange of a variety of data, including control, telemetry, and video data, between the network nodes in an extremely hostile environment,where only robots can operate.
Special Session on «Crowdsourcing and Crowdsourcing Applications»
Crowdsourcing has evolved to a sustainable business model in the Internetand a valuable tool in research. The potential to reach an enormous amount of peoplevia the Internet, who form a highly diverse workforce and provide human computation power in a very short time, offerspossibilities and new service innovations, which have been unthinkable just a few years ago. For example, conducting large scales subjective tests can now be a matter of hours instead of days.Or pollution sensing in geographic areas can be conducted in real-time.
Special Session on «Information Hiding and Security in Communications: Recent Developments»
For many decades, security and privacy are always important issues in any society. It is getting more important in the digital society where communication environments are developed in a way more openly and publicly while the amount of exchanged data required to keep secure and private is growing at a heady pace. Moreover, that is a real challenge to the research community on security and privacy while an increasing number of encryption methods have been broken by exploiting various aspects of encrypts, from mathematical analysis to observation of change in physical parameters.
Special Session on «SmartSensors»
The term Sensor was widely used from the mid-1970s. Previously, it has been existed as the word detector (detector) rather thanthe sensor, and utilized in various electric circuits or control devices. In the past, detector’ stayed at a level that only ‘sense’ a specific substance, but “sensor ” is very different in naturein that they delivers a sensing signal to the central processing unit which may make a certain judgment. The English word ‘SMART’, in the sense of’clever’, ‘wise’, has been usedforintelligentequipment or robots, but now being used even in sensors along withrecent advancesin micro-sensor technology and as the semiconductor IC technology becomes common. Smart sensor means ‘clever sensor’, i.e. the intelligent sensor. The rapid development of the conventional micro-machining techniques since 1980s allowed the realization of micro-sensors by replacing old large and heavy assembled sensors with ICs on a small silicon semiconductor substrate. Since the sensors tends to be implemented on a silicon substrate, it is possible for them to be manufactured in conjunction with semiconductor circuits such as amplification circuits, analog to digital converters, digital to analog converters, microcontrollers, etc. These sensorscan be termed as ‘micro smart sensor’in separation withthe existingintelligent sensors, but, usually reduces to call it “smart sensor”. In addition, the smart sensors are the technology that combines micro- sensors with VLSI technology, which combines the excellent data processing capability, judgment function, memory function, communication function, etc.of the computer, so that it has a number of advantages overthe conventional sensor. In recent years, smart sensors are doing pivotal role in obtaining necessary information over the time and space in conjunction with network computing technology and make various devices to function on their own. The intelligence of these sensors widens the application areabeyond the traditional limit such as smart home systems, remote health care systems, large-scale environmental monitoring systems etc.
