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.

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.

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.

In this paper we propose distributed opportunistic access techniques for femtocell-overlaid cellular networks, where each femtocell access point (FAP) decides to access the medium independently and in a distributed manner based on local link quality information. Specifically we introduce various opportunistic medium access policies, namely channel-based, interference-based, SIR-based, and rank-based, under which each FAP transmits after comparing a certain link quality metric with a predefined threshold. Considering a network in which FAPs are located according to a homogeneous Poisson point process, the performance of distributed low-overhead access schemes in terms of success probability, area spectral efficiency, and average data rate is evaluated. Furthermore, we determine the probabilistic access thresholds that provide the best possible tradeoff between spatial reuse and network throughput. Simulation results support the analysis and quantify the network throughput gains of different access policies in various operating regimes.

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.

In recent developments, regulatory bodies are introducing flexible use of spectrum such as allowing the use of temporarily unoccupied VHF and UHF bands also known as television white spaces (TVWS). The networks exploiting such opportunity, hereafter called opportunistic networks, have equal right to access available TVWS. As a result, unhealthy competition to occupy the same spectrum would be inevitable. Hence, coexistence becomes a critical issue to be addressed. We propose a distributed coexistence algorithm to be implemented by TVWS networks sharing a single TVWS channel. The TVWS networks cooperate by sharing operational parameters in order to implement self enforcing coexistence algorithms. Through the knowledge of the exchanged parameters, devices dynamically select the appropriate transmit power that minimizes the mutual interference among the cooperating networks. This increases the efficiency the available spectrum being used by the opportunistic networks and at the same time it fosters green communications by avoiding unnecessary wastage of power that builds interference between the resource competing networks. We demonstrate by simulation that choosing of optimum transmit power vector, in which each element of the vector corresponds to the optimum transmit power of particular network, ensures minimum outage occurrence that any of the cooperating networks experience link quality below a specified threshold.

This paper is focused on demonstrating a real testbed for managing logistics systems in hospital environment exploiting the benefits of M2M and IoT paradigms. The work presents an architecture based on low-cost devices interacting with an enterprise application server placed anywhere in the Internet following the architecture proposed by ETSI for M2M systems. Combining multiple communication technologies (NFC, UMTS, 802.11, ZigBee and 802.3) and adapting their capabilities to different functional requirements, we are capable of creating autonomous and self-managed systems. The deployed architecture integrates at end device level, a NFC reader for tracking the level of remaining stocks and multiple output interfaces for exchanging messages with the application server. The system copes with cost, availability, scalability and easy deployment requirements, being the functionality also adaptable to the requirements of potential customers.
