Distribution systems are evolving towards fault self-healing systems which can quickly identify and isolate faulted components and restore supply to the affected customers with little human intervention. A self-healing mechanism can considerably reduce the outage times and improve the continuity of supply;however, such an improvement requires a fast fault location method and also a communication and measurement infrastructure. In this paper the feasibility of fast service restoration through a fast fault location method is studied. A fast fault location method is proposed which is applicable to any distribution network with laterals, load taps and heterogeneous lines. The performance of the proposed method is evaluated by simulation tests on a real 13.8 kV, 134-node distribution system under different fault conditions. The results verify the applicability of the proposed architecture. We show that the communication delay plays a less important role in overall restoration time, and we stress the contribution of a fast fault location method in keeping the overall interruption time less than 1 minute.

Business processes in production and logistics need to be monitored in order to comply with official regulations, to schedule and plan the production or transport route, to ensure quality and find errors, but also to optimize the process itself. Often this monitoring needs to be done in real-time, e.g. to be able to see a potential error and take corrective actions in time. To monitor only traditional Key performance Indicators might not be sufficient though as automatization in production and logistic environments advances, the number of sensors and actuators increase and make the systems more ubiquitous but also more complex and the focus of costumers moves from pricing and quality to environmental aspects. This paper presents an architecture of a process-oriented monitoring and control framework. It makes use of visual process models to cope with the complexity of these systems and combines them with sensors and actuators. This way, processes and process steps can be monitored in detail by enriching sensor data with process information to enable detailed analysis. In a former prototype, different properties such as energy consumption in production were monitored and values were fed into a prototype developed according to the framework. In the example presented in this paper we transfer the approach to food-traceability such that the architecture is explained and validated in the context of a realistic scenario from the logistics domain. This way, we foster the transferability of the framework under development.

C-RoFN: Multi-Stratum Resources Optimization for Cloud-Based Radio over Optical Fiber networks

IEEE COMMUNICATIONS MAGAZINE 2016年第8期54卷 118-125页

C-RAN has become a promising scenario to accommodate high-performance services, which provides ubiquitous user coverage and supports real-time cloud computing using cloud BBUs. The interaction between RRH and BBU or resource schedule among BBUs in cloud have become more frequent and complex due to the development of system-scale and user requirements. The heavy-duty interaction can promote the networking demand among RRHs and BBUs, and forces to form elastic optical fiber switching and optical networking according to the characteristics of high bandwidth, low cost, and transparent multi-rate traffic transmission. In such a network, the multiple stratum resources of radio, optical, and BBU processing unit have interwoven with each other, so the traditional architecture cannot efficiently implement the resource optimization and scheduling for the high-level QoS guarantee. In this article, we present a novel C-RoFN architecture for MSRO using software defined networking. The proposed architecture can globally optimize radio frequency, optical spectrum, and BBU processing resources effectively to maximize radio coverage and meet the QoS requirement. The functional modules of C-RoFN architecture, including the core elements of radio, optical, and BBU controllers, are described in detail. The cooperation procedures in multi-layer vertical integration and cross-stratum horizontal merging models are investigated. The overall feasibility and efficiency of the proposed architecture are also experimentally demonstrated on our SDN-enabled testbed with OpenFlow-enabled elastic optical nodes, and compared to cross-stratum optimization strategy in terms of resource occupation and path provisioning latency. Numerical results are given and analyzed based on the testbed. Some future discussions are presented in the conclusion.

With the advent of internet of Things (IoT), an increasing number of devices may spontaneously communicate to exchange information. This puts emphasis on wireless sensor networks (WSNs) and, in particular, on intelligent medium access control (MAC) protocols, as there is a need to guarantee a certain quality of service (QoS) on timely data/packet delivery. Most existing approaches, however, are either of random nature, making it impossible to guarantee any bounded delay, or do not scale well for a higher number of nodes. As a result, we propose slot sharing TDMA (short s2TDMA), a deterministic contention resolution scheme in form of generating TDMA cycles with shared slots at the event of collisions. Every TDMA slot is assigned to a range of IDs, in which the corresponding nodes can transmit. By further dividing these slots in case of collisions, we implement an interval tree search enabling for fast collision resolution in logs-complexity, where s is the number of slots in each cycle. Since our scheme is activated upon collisions, it incurs in zero overhead during normal operation and is able to quickly react to changing traffic load such as bursty traffic. We perform a large set of detailed simulations on OMNeT++ showing that our technique offers a fast collision resolution and is able to handle a large number of nodes in the network. © 2016 ACM.

This work proposes an innovative technique to solve the problem of tracking and following a generic human target by a drone in a natural, possibly dark scene. The algorithm does not rely on color information but mainly on shape information, using the HOG classifier, and on local brightness information, using the optical flow algorithm. We tried to keep the algorithm as light as possible, envisioning its future application on embedded or mobile devices. After several tests, performed modeling the system as a set of SISO feedback-controlled systems and calculating the Integral Squared Error as quality indicator, we noticed that the final performance, overall satisfactory, degrades as the background complexity and the presence of disturbance sources, such as sharp edges and moving objects that cross the target, increase.

Vehicular Cyber Physical systems (VCPS) are envisioned to enable novel approaches to managing and controlling future road traffic intersections. Previous efforts on autonomous intersection control (AIC) mainly focused on collisions avoidance and traffic efficiency, without considering travel experience from passengers' perspective. In this work, we design a convex optimization based AIC mechanism. In particular, we design the metric of smoothness with the objective of quantitatively capturing the quality of travel experience and transform the objective into a convex function. In addition, we linearize collision avoidance constraints by designing a schedule rule, which determines the priority of vehicles when passing through the intersection according to the travel time of individual vehicles. On this basis, we propose a new algorithm to achieve the optimal solution with low overhead. Finally, we build the simulation model and implement the algorithm for performance evaluation. Comprehensive simulation results demonstrate the superiority of the proposed algorithm.

Due to development of the internet, the size of data continue to be large and rough. During the process of data collection, different kinds of data problems occurred, among where incompleteness is one of the most serious problems to deal with. The existing methods for missing values imputation have mostly relied on using statistics and machine learning. These methods are known to be limited in efficiency and accuracy, which are caused by high dimensional calculation and low quality of initial data. In this paper, we propose a new method combining Bayesian network and crowdsourcing to deal with missing values together. We use Bayesian network to inference missing values to improve efficiency while use crowdsourcing to obtain additional information in need to improve accuracy. Experiments on real datasets show that our methods achieve better performance compared to other imputation methods. © Springer International Publishing Switzerland 2016.
