An ideal IoT solution for real-time web monitoring

For the internet of things (IoT) to fully emerge, it is necessary to design a suitable system architecture and specific protocols for this environment. The former to provide horizontal solutions, breaking away the current paradigm of silos solutions, and thus, allowing the creation of open and interoperable systems; while the latter will offer efficient and scalable communications. This paper presents the latest standards and ongoing efforts to develop specific protocols for IoT. Furthermore, this paper presents a new system, with the most recent standards for IoT. Its design, implementation and evaluation will be also described. The proposed system is based on the latest ETSI M2M specification (ETSI TC M2M in ETSI TS 103 093 V2.1.1. http://www.etsi.org/deliver/etsi_ts/103000_103099/103093/02.01.01_60/ts_103093v020101p.pdf , 2013b) and the MQTT protocol (IBM, Eurotech in MQTT V3.1 Protocol Specification pp 1–42, http://public.dhe.ibm.com/software/dw/webservices/ws-mqtt/MQTT_V3.1_Protocol_Specific.pdf , 2010). With this solution it is possible to show how we can create new applications to run over it and the importance of designing specifically tailored for IoT communication protocols in order to support real-time applications.

Securing Vehicular IPv6 Communications

A common practice is applying security after a network has been designed or developed. We have the opportunity of not committing this error in vehicular networks. Apart from particular works in the literature, ETSI TC ITS has defined general security services for (vehicular) cooperative systems. However, existent efforts do not pay the needed attention to the integration of IPv6 yet. The potential of IPv6 in the field is being described within ISO TC 204, above all, but further work is needed for a proper integration of security. This work follows this direction, and a reference vehicular communication architecture considering ETSI/ISO regulations, uses Internet Protocol security (IPsec) and Internet Key Exchange version 2 (IKEv2) to secure IPv6 Network Mobility (NEMO). A key advance is also the implementation and experimental evaluation of the proposal in a challenging vertical handover scenario between 3G and 802.11p. The performance of the secured NEMO channel is widely analyzed in terms of the movement speed, bandwidth, traffic type or signal quality, and it is concluded that the addition of IPv6 security only implies a slight reduction in the overall performance, with the great advantage of providing confidentiality, integrity and authenticity to the communication path.

Security of Cooperative Intelligent Transport Systems: Standards, Threats Analysis and Cryptographic Countermeasures

Due to the growing number of vehicles on the roads worldwide, road traffic accidents are currently recognized as a major public safety problem. In this context, connected vehicles are considered as the key enabling technology to improve road safety and to foster the emergence of next generation cooperative intelligent transport systems (ITS). Through the use of wireless communication technologies, the deployment of ITS will enable vehicles to autonomously communicate with other nearby vehicles and roadside infrastructures and will open the door for a wide range of novel road safety and driver assistive applications. However, connecting wireless-enabled vehicles to external entities can make ITS applications vulnerable to various security threats, thus impacting the safety of drivers. This article reviews the current research challenges and opportunities related to the development of secure and safe ITS applications. It first explores the architecture and main characteristics of ITS systems and surveys the key enabling standards and projects. Then, various ITS security threats are analyzed and classified, along with their corresponding cryptographic countermeasures. Finally, a detailed ITS safety application case study is analyzed and evaluated in light of the European ETSI TC ITS standard. An experimental test-bed is presented, and several elliptic curve digital signature algorithms (ECDSA) are benchmarked for signing and verifying ITS safety messages. To conclude, lessons learned, open research challenges and opportunities are discussed.

Connecting and Managing M2M Devices in the Future Internet

As a cutting edge technology, Machine to Machine (M2M) communications are gaining ground for managing and controlling M2M devices. Since these objects have intelligence, communication capabilities and ability to work with their environment, they are considered as a key component for future smart buildings and cities. In this article we briefly introduce several architectures for M2M devices, which are being standardized in 3GPP, ETSI TC M2M and OneM2M, highlighting key functionalities used to manage and control M2M devices such as overload control, conflict management and semantic interworking. Further, the description of their realization in the field of smart building, as part of the CAMPUS 21 European project based on the M2M service modeling from the SENSEI European project, is presented.

Latest trends in telecommunication standards

Standardization organizations play a major role in the telecommunications industry to guarantee interoperability between vendors and allow for a common ground where all players can voice their opinion regarding the direction the industry should follow. In this paper we review the current activities in some of the most relevant standardization bodies in the area of communication networks: 3GPP, IEEE 802.11, BBF, IETF, ONF, ETSI ISG NFV, oneM2M and ETSI TC ITS. Major innovations being developed in these bodies are summarized describing the most disruptive directions taken and expected to have a remarkable impact in future networks. Finally, some trends common among different bodies are identified covering different dimensions: i) core technology enhancements, ii) inter-organizations cooperation for convergence, iii) consideration of raising disruptive technical concepts, and iv) expanding into emerging use cases aiming at an increase of future market size.

Design and performance evaluation of a PMIPv6 solution for geonetworking-based VANETs

Vehicular Ad hoc NETworks (VANETs) are considered as the most suitable technology to provide vehicles with communication capabilities as a mean to improve road safety. Additionally, VANETs also open the market to non-safety applications where Internet connectivity is the main focus. Internet access from VANETs can be provided with the support of gateways located at the side of the roads, such that vehicles change their point of attachment to the Internet maintaining ongoing communications while they move. In this paper we tackle the problem of providing Internet access from VANETs combining the Proxy Mobile IPv6 (PMIPv6) with the ETSI TC ITS GeoNetworking (GN) protocols. We study how to adapt PMIPv6 to the multi-hop ETSI TC ITS architecture. A key contribution of this work is the design and analysis of different mechanisms that can be applied to the solution to improve the overall performance. A detailed performance evaluation of the solution and the different mechanisms assessing their influence is conducted by means of simulation under real traffic traces of an important orbital highway of Madrid.

IPv6 Security Issues in Cooperative Intelligent Transportation Systems

Cooperative Intelligent Transportation Systems (ITS) will turn up to us with safer and more efficient driving environments as well as convenient and infotainment features for future ITS stations. ETSI and ISO are completing the standardization of the building blocks of a reference communication architecture for cooperative ITS. Future ITS stations complying with this set of standards deployed in vehicles, at the roadside infrastructures and within the Internet are expected to communicate with each other through a combination of ITS dedicated communication protocols and legacy Internet protocols. However, in spite of the wide adoption of IPv6 for cooperative ITS communications, relatively little attention has been paid to the security issues related to IPv6 signaling and IPv6 transport communications. In this paper, we present our position on the emerging and urgent IPv6-related security issues that occur in communications between ITS stations complying with the ITS station reference architecture under standardization within ETSI TC ITS and ISO TC204.

Satellite radio interfaces compatible to 3GPP WCDMA system

AbstractThis paper provides an overview of a technical study on the satellite radio interfaces based on 3GPP WCDMA system. First, the outcome of the technical study is introduced, which has been carried out by the Mobile Satellite System Working Group of the ETSI Satellite Earth Satellite Technical Committee (ETSI TC SES MSS). The study dealt with the configurations and performance of the 3GPP WCDMA (UTRAN) radio interface over a satellite link. Second, as an evolution of satellite‐specific radio interface, the study results are addressed on the possible adaptations of WCDMA to the satellite link in order to maximize the radio link performance. The resultant outcome of the study was reflected in a detail on the G and C families of the satellite radio interface of the ITU‐R Recommendation M.1457, respectively.
