By giving vehicles the ability to propagate warning messages to the other ones, the number and the severity of accidents on our streets could likely be reduced. Safety-related applications based on vehicular ad-hoc neworks (VANET) are usually dependent on transmitting a message from source to sink within a given time limit. IEEE proposes the standard 802.11p which is an adaption of the well-known Wireless LAN 802.11a for inter-vehicle communication. While many properties have been improved, 802.11p still comes with a contention-based medium access control, only. This leads to an indeterminism and data-dependencies. One deterministic and fairer alternative compared to contention based medium access mechanism would be Time-Divison Multiple Access (TDMA). As a VANET is typically fully self-organizing, the time slots must be assigned autonomously by the nodes of the distributed system. This, however, leads to drawbacks in the performance of the protoctol which are analyzed in this paper.

Although the number of accidents that occur on roads is slowly decreasing in time, as both cars and streets become progressively safer, the Statistics of Road Traffic Accidents study from the United Nations reveals that during the last decade every year an average of 150,000 people have lost their lives and 5.5 million have suffered injuries on the roads of western countries. Among the many proposals that have been made, during the years, to combat such phenomenon, an important place is taken by highway accident warning technologies. Such type of system can play an important role, especially in those cities, like Los Angeles, Seoul and Shanghai, specifically designed for cars, more than for human beings. In fact, when an accident occurs on a highway of a city like Los Angeles, it is vital to warn as rapidly as possible all the approaching vehicles, in order to give them the time to stop before crashing on any unexpected obstacle. Recently, an inter-vehicular accident warning system has been devised, theoretically proven to be optimal in terms of bandwidth usage and covered distance. In this paper, we present preliminary results that assess the feasibility of such system. The presented results and measurements were taken from real experiments, performed on Los Angeles freeways and roads in August 2011. To the best of our knowledge, these are the first real experiments of such magnitude performed in a live setting with an inter-vehicular accident warning system.

The advancement of cognitive radio and dynamic spectrum access systems technologies is being driven by multiple different stakeholders including technology enthusiasts, research programs, industry consortia and regulatory bodies worldwide. These stakeholders are driving early standards developments; however their often disparate visions are leading to a fractured standards landscape that may harm, versus help, mainstream adoption. Harmonizing these disparate visions requires a common “forum” responsible for advancing cognitive radio and dynamic spectrum access across markets. A case study from one such forum shows that these objectives can be achieved following such a model.

We address the problem of coexistence between neighboring cognitive wireless networks operating in the TV White Space (TVWS). We derive an interference model to predict the range and level of interference generated in the TV bands by portable low-heigh antenna cognitive wireless access points (AP) in suburban and urban areas. Based on our model, we provide an analysis of the spectral availability (SA) for either the scenarios where dynamic frequency selection (DFS) coexistence technique is employed or not. We derive the steps of our analysis and provide, as an illustrative example, the expected coexistence performance of TVWS enabled cognitive wireless APs in Japan. Our analysis demonstrates the intrinsic relationship SA holds with the TVWS channel set as well as statistical information, e.g., house-hold density of wards and cities, Internet penetration, White Space (WS) radio AP market penetration.

Spectrum sensing and compulsory idling are two important functionalities of the overlaid Cognitive Radio (CR) to facilitate the opportunistic spectrum access and incumbent protection for primary user systems. Since both the spectrum sensing and compulsory idling introduce energy-overheads to CR users, it is critical for CR to balance between these additional energy-overheads and its energy consumption for effective data transmission. We thus propose energy-efficient transmission policies for CR that aims at minimizing its total cost (including both energy consumption and delay cost) to deliver a target traffic payload. We formulate this problem as a stochastic shortest path Markov decision process and obtain the optimal rate-adaptation policy via the value iteration. We further propose a low-complexity rate-adaptation policy through the certainty equivalent control with approximation to save computational complexity. Numerical results show the low-complexity policy achieves comparable performance as the optimal policy.

Deploying decode-and-forward relay nodes is a promising solution for LTE-advanced networks in order to meet the growing data rate demand and the challenging requirements for coverage extension. However, relay selection scheme plays a crucial role in enhancing the benefit of this technology. In this paper, we have proposed a new relay selection scheme which achieves a more balanced load in the network, respects the user's quality of service requirements, but more importantly, avoids recurrent handovers and reduces the transmission delay. Simulation results proved a significant enhancement of the system performance in terms of outage probability, total system throughput and delay as compared to common relay selection strategies.

This paper gives an overview on the possibilities and potential of dynamic vertical beamsteering in a cellular mobile radio system with focus on the interference limited macro-cell scenario. Different realization options for dynamic terminal specific downtilt adaptation at the base station (eNB) are introduced and simulated performance figures are given. Beam coordination methods for interference avoidance without and with the requirement for inter-eNB communications are considered. The impact of the most important system parameters like downtilt angle variation and coordination algorithm parameter setting is investigated. Basic measurements in real environment for proof of concept are introduced and their relation to simulation results are discussed. Finally the major conclusions and an outlook for future investigations are given.

This paper introduces novel results in the area of Cognitive Radio System (CRS) aspects and Control Channels for Cognitive Information Sharing as they are currently elaborated in the framework of the ETSI Reconfigurable Radio Systems (RRS) Technical Body. An overview of the most relevant scenarios for CRS employing opportunistic spectrum usage in the TV White Spaces is given as well as an analysis of inherently required context information provisioning solutions. Finally, an overview on the related regulatory activities and future regulatory challenges are indicated with an emphasis on expected per-device certification mechanisms which will finally enable the introduction of “RadioApps”, i.e. software components provided to Mobile Devices (MD) which will affect the compliance of MDs to the essential requirements of the R&TTE Directive in Europe.

Ultra low-power radio-frequency identification (RFID) tag with precision localization is often the enabling technology for location-aware sensor applications. Impulse-Radio Ultra-Wideband (IR-UWB) is a promising technology to fulfill the usage requirements in indoor cluttered environment. An ultra low-power precise UWB-RFID localization system is proposed in this paper. The RFID tag is a transmitter comprising of a micro-controller board and a UWB impulse radio board. Power saving and precision localization is achieved by optimization of the circuit design for ultra short pulses as well as system architecture and operation. When 1 s sleep mode is incorporated with 0.72 ms active mode, the tag consumes on average 6.8 uA when pulsing at 3.3 MHz rate with 15.5 dBm peak transmit power. The transmitted pulse is captured by low-cost energy-detection receivers at the locator. Measurement in a 6m×6m typical indoor environment demonstrates that the proposed system is able to achieve positioning accuracy of 10 cm. Due to the high sensitivity of the receiver (-71 dBm), the proposed system can reach a potential reading range of over 100 meters. The ultra low-power consumption, accurate ranging and positioning result, and long reading distance makes the proposed system suitable for a variety of intelligent sensor applications.

In this paper we propose a novel secure tag ownership transfer scheme for closed loop RFID systems. An important property of our method is that the ownership transfer is guaranteed to be atomic and the scheme is protected against desynchronisation leading to permanent DoS. Further, it is suited to the computational constraints of EPC Class-1 Gen-2 passive RFID tags as they only use the CRC and PRNG functions that passive RFID tags are capable of. We provide a detailed security analysis to show that our scheme satisfies the required security properties of tag anonymity, tag location privacy, forward secrecy, forward untraceability while being resistant to replay, desynchronisation and server impersonation attacks. Performance comparisons show that our scheme is practical and can be implemented on passive low-cost RFID tags.
