    System Spectral Efficiency and Stability of 3G Networks: A Comparative Study

    CDMA2000, WCDMA and WiMAX are three widely used 3G technologies. Since they share the same goal, which is to provide broader coverage and higher throughput in 3G networks, an impartial comparison of their performance is indispensable. However, they are based on different design principles and methodologies, which make the comparison...

    Impact of WiMAX Network Asymmetry on TCP

    The IEEE 802.16 is the standard for broadband wireless access. One promise of this technology (also called WiMAX) is to provide high-speed access to the Internet where the transmission control protocol (TCP) is the core transport protocol. This paper studies the impact of network asymmetry in WiMAX on TCP performance....

    Secure Socket SCTP: A Multi-Layer End-to-End Security Solution

    Stream Control Transmission Protocol (SCTP) is a rather new full-fledged transport protocol with a rich set of functionalities. In SCTP, transport layer multi-homing for enhanced network fault tolerance is provided. The concept of multi-streaming is also included to reduce the impact of head-of-line blocking of unrelated data. In addition, enhanced...

    Dynamic Parameter Tuning for Hardware Prefetching Using Shadow Tagging

    The performance of general purpose microprocessors continues to increase at a rapid pace, but main memory has not been able to keep up. In essence, the processor is able to process several orders of magnitude more data than main memory is able to deliver on time. Numerous techniques have been...

    Scheduling in Multiprocessor System Using Genetic Algorithms

    Real-time systems are software systems in which the time at which the result is produced is as important as the logical correctness of the result. Multiprocessors have emerged as a powerful computing means for running real-time applications, especially where a uniprocessor system would not be sufficient enough to execute all...

    Business Domain Models in ERP Development

    Business domain models play an important role in the context of ERP systems implementations, where e.g. industry specific reference models are used to set up the ERP systems at the end user organizations. In this paper, the authors will focus on another, less researched, part of ERP software practice where...

    Performance Effects of a Cache Miss Handling Architecture in a Multi-core Processor

    Multi-core processors, also called Chip Multi-Processors (CMPs), have recently been proposed to counter several of the problems associated with modern superscalar microprocessors: limited Instruction Level Parallelism (ILP), high power consumption and large design complexity. However, the performance gap between a processor core and main memory is large and growing. Consequently,...

    On Stochastic Modeling for Integrated Security and Dependability Evaluation

    In this paper, the authors present a new approach to integrated security and dependability evaluation, which is based on stochastic modeling techniques. Their proposal aims to provide operational measures of the trustworthiness of a system, regardless if the underlying failure cause is intentional or not. By viewing system states as...

    On a Family of Minimal Candidate One-Way Functions and One-Way Permutations

    The concept of one-way function is the fundamental concept in the modern cryptography and was first introduced by Diffie and Hellman in their seminal paper. Since then, many designed cryptographic primitives that claim that are cryptographically strong, actually suppose that they have implemented the concept of one-wayness in some proper...

    Edon-R, An Infinite Family of Cryptographic Hash Functions

    Cryptographic hash functions are used in a wide range of applications including message integrity, authentication, digital signature and public key encryption. A cryptographic hash function takes an input of arbitrary size and produces an output, also called the hash value, of a fixed, predetermined size. The important properties of a...
