- Feedback-Based Scheduling for Back-End Databases in Shared Dynamic Content Server Clusters
- This paper introduces a self-configuring architecture for scaling the database tier of dynamic content web servers. The authors use a unified approach to load and fault management based on dynamic data replication and feedback-based scheduling. While replication provides scaling and high availability, feedback scheduling dynamically allocates tasks to commodity databases...

- The Need for Cross-Layer Service Discovery in MANETs
- Service selection has a crucial effect on wireless multi-hop ad hoc network MANET performance. Because of the broadcast nature of wireless transmission, good service selection groups clients with nearby service providers, localizing communication, which in turn reduces inter-node interference and allows for multiple concurrent transmissions in different parts of the...

- An Investigation of the Characteristics of Spyware Programs
- During the last few years, several kinds of malicious software have become increasingly spread throughout the online community. Numerous variants of such software exist in the wild: malware, ad-ware, spyware, viruses, backdoors, trojans, worms are only a few of these. While there exist tools to eliminate some of these programs,...

- Differential Modulation Diversity for OFDM
- The application of Differential Modulation Diversity DMD to orthogonal frequency division multiplexing with multiple transmit and/or receive antennas is considered. Based on diagonal signals originally designed for differential space-time modulation, DMD is used to exploit both space and frequency diversity. At the receiver, low-complexity decision-feedback differential detection without channel state...

- Improved Correlation-Based Channel Estimators for DS-CDMA
- Channel estimates obtained using the conventional correlation-based approach are biased when short spreading sequences are employed in CDMA systems. In addition, they suffer from Inter-Path Interference IPI due to the non-zero autocorrelation values of typical spreading sequences. For long-code systems, sometimes known as aperiodic spreading, the estimates are unbiased but...

- Stochastic Analysis of Network Coding in Epidemic Routing
- Epidemic routing has been proposed to reduce the data transmission delay in disruption tolerant wireless networks, in which data can be replicated along multiple opportunistic paths as different nodes move within each other's communication range. With the advent of network coding, it is intuitive that data can not only be...

- A Min-Plus System Interpretation of Bandwidth Estimation
- Significant research has been dedicated to methods that estimate the available bandwidth in a network from traffic measurements. While estimation methods abound, less progress has been made on achieving a foundational understanding of the bandwidth estimation problem. This paper develops a min-plus system theoretic formulation of bandwidth estimation. The paper...

- Linear Precoding for Multiuser MIMO-OFDM Systems
- This paper develops linear precoding schemes for the downlink in multiuser Multiple-Input Multiple-Output MIMO Orthogonal Frequency Division Multiplexing OFDM systems with multiple data streams per user. The authors extend an existing multiuser MIMO algorithm, that jointly optimizes the power allocation and the transmit and receive filters, to MIMOOFDM systems. One...

- Negotiation-Based Service-Oriented Software Process in Peer-to-Peer Environments
- Among many emerging technologies, service-oriented architecture and peer-to-peer networking are significantly changing not only the properties of applications, but the way to develop them. In this paper, the authors envision a convergence of these two - peer service systems. However, how to efficiently develop distributed applications in such peer service...

- An Introduction to Multicarrier Modulation
- Multicarrier modulation helps to reduce the detrimental effects of multipath fading. Because of its robustness to multipath, and the ease of implementing it in transmitters and receivers using the Fast Fourier Transform FFT, the MCM concept is growing rapidly in practical importance. It can be found today in IEEE standards...

- Adaptive Channel SVD Estimation for MIMO-OFDM Systems
- In this paper an adaptive estimation algorithm for channel matrix singular value decomposition SVD in multiple-input multiple-output MIMO orthogonal frequency division multiplexing OFDM systems is proposed. The SVD method is an efficient approach to design space-time coding/decoding and detection algorithms in MIMO-OFDM systems. However, the SVD estimation may involve complex...
