    Differential Privacy in Practice

    The authors briefly review the problem of statistical disclosure control under differential privacy model, which entails a formal and ad omnia privacy guarantee separating the utility of the database and the risk due to individual participation. It has born fruitful results over the past ten years, both in theoretical connections...

    A Survey of Security Mechanisms with Direct Sequence Spread Spectrum Signals

    Security has long been a challenging problem in wireless networks, mainly due to its broadcast nature of communication. This opens up simple yet effective measures to thwart useful communications between legitimate radios. Spread spectrum technologies, such as Direct Sequence Spread Spectrum (DSSS), have been developed as effective countermeasures against, for...

    Enhanced QRD-M Algorithm for Soft-Output MIMO Detection

    QR-decomposition with M algorithm is a promising technique for Multi-Input Multi-Output (MIMO) systems. When the number of candidates is insufficient, its performance is, however, degraded due to an inaccurate Log Likelihood Ratio (LLR). To address this problem, an enhanced soft LLR calculation scheme is proposed for soft-output MIMO detection. Based...

    Advanced Logical Superposition Modulation Based Video Streaming Multicast System Over Wireless Networks

    In this paper, the authors present an advanced logical superposition modulation based video streaming multicast system over a wireless networks. The traditional logical superposition modulation scheme generates symbols using a prefixed modulation scheme to overcome wireless channel diversity. In contrast, their proposed logical superposition modulation determines logical superposition modulation scheme...

    Multi-Rate Combination of Opportunistic Routing and Network Coding: An Optimization Perspective

    Recently, wireless communication methods that exploit the broadcast nature of the wireless medium have been attracting growing attention. Among these methods, opportunistic routing and network coding are regarded as the most promising techniques. While there have been some attempts to combine opportunistic routing with network coding to capture the advantages...

    Directory-Hopping Based Service Discovery for Dynamic Large-Scale Wireless Networks

    With the rapid growth of wireless communication technologies, the demands for large-scale wireless networks have been emerged. One promising solution is the hierarchical architecture that consists of global and local wireless networks. The service discovery is a key issue to meet a vast amount of service demands from mobile nodes....

    Low-Complexity Near-Optimal Presence Detection of a Linearly Modulated Signal

    Spectrum sensing is an activity of a Cognitive Radio to detect the presence of a primary user in the frequency band of interest. In this paper, the authors consider under the Neyman-Pearson criterion the detection of a primary user signal that linearly modulates codeword symbols from a Gaussian codebook. To...

    Business Process Mining: An Industrial Application

    Contemporary information systems (e.g., WfM, ERP, CRM, SCM, and B2B systems) record business events in so-called event logs. Business process mining takes these logs to discover process, control, data, organizational, and social structures. Although many researchers are developing new and more powerful process mining techniques and software vendors are incorporating...
