In this paper, the problem of secrecy sum-rate maximization is addressed for a multiuser multiple-input multiple-output wiretap channel. We consider the case of a single eavesdropper, when the information signals of the legitimate users are spatially multiplexed by using either zero forcing beamforming (ZFB) or Tomlinson-Harashima precoding (THP). By exploiting channel correlation of legitimate users with the eavesdropper, two low-complexity user selection schemes are investigated. In both schemes, the key idea is to extract multiuser diversity in order to protect information signals from eavesdropping rather than creating jamming interference. In the first scheme, user selection is performed in the null space of the eavesdropper's channel and an iterative power allocation method is proposed. In the second scheme, the eavesdropper is considered to be a selected authorized user but its allocated power is forced to be zero. Numerical results are provided to illustrate the secrecy sum-rate performance of the proposed schemes.

This paper deals with the implementation of a Nonlinear Interference Suppressor (NIS) into a wireless LTE transceiver. This within the context of high energy efficient multi-standard transceivers controlled by a cognitive radio platform. In multimode transceivers, the transmitter for one communication standard may induce a large interferer in the receiver for another standard. To linearly suppress this interferer, which can be several orders of magnitude larger than the desired received signal, the receiver should have a very large linear dynamic range, resulting in excessive power consumption. For this reason, we consider the NIS, a closed-loop tuning method that exploits the locally available interference as side information. The wireless LTE transceiver model, includes all the baseband signal treatment blocks and the RF front-end of a low IF direct conversion receiver architecture. A mobile WiMAX signal is considered as the interference signal at the receiver. The obtained symbol error rate (SER) is observed for different system configurations. Matlab simulation results in this practical scenario show that the NIS can strongly suppress the interferer while a symbol error rate performance close to that of an exactly linear receiver is achieved. This results permit to identify perspective directions for the better multi-standard and high energy efficient transceivers implementation. © 2013 IEEE.

This paper presents a research study consisting of a comparison analysis of replication and retrieval of medical image data which use the Digital Imaging and Communications in Medicine (DICOM) standard. These data are stored in a relational database management system (RDBMS) and in the Hierarchical Data Format (HDF) using a distributed file system as a data backend. The importance of this work was measured by verification of elapsed-time reduction for medical image data replication and retrieval in a real telemedicine environment.

The present paper demonstrates through experiments that the performance of a teleoperated robot system is strongly influenced by the quality of the communication environment, which in our case was a wireless LAN (WLAN). We analyzed the path following capability of a human operator in the case of a teleoperated robot, with haptic feedback. We investigated the influence of external WLAN traffic over the precision of robot tracking. The paper presents both the design of the bilateral teleoperation system for mobile robots and the experimental methodology for performance evaluation of teleoperation systems in open wireless networks. © 2013 IEEE.

Text mining in negative relevance feedback

It is a big challenge to clearly identify the boundary between positive and negative streams. Several attempts have used negative feedback to solve this challenge;however, there are two issues for using negative relevance feedback to improve the effectiveness of information filtering. The first one is how to select constructive negative samples in order to reduce the space of negative documents. The second issue is how to decide noisy extracted features that should be updated based on the selected negative samples. This paper proposes a pattern mining based approach to select some offenders from the negative documents, where an offender can be used to reduce the side effects of noisy features. It also classifies extracted features (i.e., terms) into three categories: positive specific terms, general terms, and negative specific terms. In this way, multiple revising strategies can be used to update extracted features. An iterative learning algorithm is also proposed to implement this approach on RCV1, and substantial experiments show that the proposed approach achieves encouraging performance. © 2012 - IOS Press and the authors.

Intrusions in computer networks have driven the development of various techniques for intrusion detection systems (IDSs). In general, the existing approaches seek two goals: high detection rate and low false alarm rate. The problem with such proposed solutions is that they are usually processing intensive due to the large size of the training set in place. We propose a technique that combines a fuzzy ARTMAP neural network with the well-known Kappa coefficient to perform feature selection. By adding the Kappa coefficient to the feature selection process, we managed to reduce the training set substantially. The evaluation results show that our proposal is capable of detecting intrusions with high accuracy rates while keeping the computational cost low.

Petrakis Stefan Covaci Paolo Zampognaro Eleni Georga Christoph Thuemmler Technical University of Crete (TUC) Intelligence Lab Chania Crete Greece Internet services platforms at the computer sciences and electrical engineering Institute for Telecommunication Systems R & D Lab of Engineering Ingegneria Informatica S.p.A.

The emergency of cloud computing and Generic Enablers (GEs) as the building blocks of Future Internet (FI) applications highlights new requirements in the area of cloud services. Though, due to the current restrictions of various certification standards related with privacy and safety of health related data, the utilization of cloud computing in such area has been in many instances unlawful. Here, we focus on demonstrating a “software to data” provisioning solution to propose a mapping of FI application use case requirements to software specifications (using GEs). The aim is to establish a provider to consumer cloud setting wherein no sensitive data will be exchanged but it will reside at the back-end site. We propose a prototype architecture that covers the cloud management layer and the operational features that manage data and Internet of Things devices. To show a real life scenario, we present the use case of the diabetes care and a FI application that includes various GEs.
