Comprehensive networks of intelligent products and production systems in Industry 4.0 enable an autonomous and decentralized manufacturing organization and the capability for self-control and self-optimization. Standardized communication and data exchange is the key to establish the interaction of entities and systems along the entire value chain. This paper analyses requirements of Industry 4.0 and discusses the capabilities of propagated communication protocols.

Wireless sensor networks (WSNs) are composed of a large number of sensor nodes that are typicallybattery-powered and designed to operate for a long period. Application areas are many and varied, such as the environmental field, medical and military.The major advantage of this device is a large-scale deployment without any maintenance. The sensors do not need to achieve an established infrastructure to transmit vital data to the study of the environment. It is also necessary to ensure good quality service, because without son sensor networks must incorporate mechanisms that allow users to extend the life of the entire network, as each node is supplied by a limited power source and generally irreplaceable. Therefore, it is necessary to optimize the power consumption at all levels of design of this type of network. Accordingly, minimization of power consumption is one of the most important design factors in sensor networks.The aim of this thesis is study the different existing routing techniques in a context without multi-hop son to get better performance. We carry our study of the most popular routing protocols to offer in a second part a new routing protocol for optimizing energy consumption without son sensor networks, keeping an optimal quality of service. ; Les réseaux de capteurs sans fil (RCSFs) sont constitués d'un grand nombre de noeuds de capteurs qui sont généralement alimentés par batterie et conçu pour fonctionner pendant une grande période.

The obligations of researchers to disclose clinically and/or personally significant individual research results are highly debated, but few empirical studies have addressed this topic. We describe the development of a protocol for returning research results to participants at one site of a multicenter study of the genetic epidemiology of melanoma. Protocol development involved numerous challenges: (1) deciding whether genotype results merited disclosure; (2) achieving an appropriate format for communicating results; (3) developing education materials; (4) deciding whether to retest samples for additional laboratory validation; (5) identifying and notifying selected participants; and (6) assessing the impact of disclosure. Our experience suggests potential obstacles depending on researcher resources and the design of the parent study, but offers a process by which researchers can responsibly return individual study results and evaluate the impact of disclosure.

The Japanese government aims to introduce self-driven vehicles by 2020 to reduce the number of accidents and traffic jams. Various methods have been proposed for traffic control at accident-prone intersections to achieve safe and efficient self-driving. Most of them require roadside units to identify and control vehicles. However, it is difficult to install roadside units at all intersections. This paper proposes an inter-vehicle communication protocol that enables vehicles to transmit their vehicle information and moving direction information to nearby vehicles. Vehicles identify nearby vehicles using images captured by vehicle-mounted cameras. These arrangements make it possible for vehicles to exchange yielding intention at an unsignalized intersection without using a roadside unit. To evaluate the operations of the proposed protocol, we implemented the protocol in Raspberry Pi computers, which were connected to cameras and mounted on radio control cars and conducted experiments. The experiments simulated an unsignalized intersection where both self-driven and human-driven vehicles were present. The vehicle that had sent a yielding request identified the yielding vehicle by recognizing the colour of each radio control car, which was part of the vehicle information, from the image captured by its camera. We measured a series of time needed to complete the yielding sequence and evaluated the validity of yielding decisions.

Vehicular ad hoc networks allow the exchange of information between vehicles to improve road safety. In addition, vehicles can be connected to the Internet through gateways placed alongside the roads, which allow drivers to use common Internet services and new applications specifically oriented to them. The European Telecommunications Standards Institute Technical Committee Intelligent Transport System has standardised the architecture and the communication protocols for an Intelligent Transport System, considering both safety applications and communications with the Internet. The GeoNetworking (GN) protocol has been designed to forward packets inside the vehicular ad hoc network taking safety requirements as the main concern. This paper analyses the GN protocol focusing on the provision of Internet connectivity to vehicles. The main contributions of this work are the identification of sources of performance losses when using the GN protocol in communications with the Internet and the proposal of different mechanisms to improve its performance in this type of communications. The evaluation of the GN protocol and the proposed improvements is conducted by means of extensive simulations. ; This work has been funded by the Spanish MICINN through the I‐MOVING and ADAS‐ROAD projects (TEC2010‐18907 and TRA2013‐48314‐C3‐1‐R) and the Comunidad de Madrid government through the MEDIANET project (S2009/TIC‐1468).

Enabling people to make an informed choice on whether to change consumption behavior is ultimately the objective of any fish consumption advisory. This will occur only if people are aware of the advisory, know and understand the advisory information, and believe the information to be true. Interactive, meaningful communication and the opportunity to participate in the process to develop and review advisories are key to achieving these attributes. A case study was undertaken in a community in Alberta, Canada (where an existing advisory was under consideration for review) to determine public awareness, knowledge, compliance, communication effectiveness, information needs, and desire for involvement related to the advisory. The information obtained from this case study was used to develop 14 guiding principles as a foundation for the incorporation of public participation and risk communication into the process of developing and reviewing fish consumption advisories.

ABSTRACT The Internet of Things (IoT) technology embedded in smart grids, smart homes, communication, education, business, retail, agriculture, government services, and other areas has had a huge effect on our daily lives. On battery-powered networks, LoRaWAN protocol is utilized for providing Internet-based objects, like localized relocation, secure communications, and utilization. The goal of this research is to assess the LoRaWAN protocol and its data communication on the IoT.

The aim of this paper is to explain the need to organize the development of standard protocols for communication about major public risks. Tragic events, such as inadequate earthquake preparedness or great unnecessary losses of life due to public misunderstandings underline the importance of such protocols to protect the public and support confidence in government and experts. The required contents of such protocols are suggested in outline. It is concluded that the need is urgent internationally to organize the development of standard protocol paradigms, one for scientific-professional analysts and another for authorities' communications to the public. ; Non UBC ; Unreviewed ; This collection contains the proceedings of ICASP12, the 12th International Conference on Applications of Statistics and Probability in Civil Engineering held in Vancouver, Canada on July 12-15, 2015.
