Hybrid Intrusion Detection with Weighted Signature Generation over Anomalous Internet Episodes(HIDS)

Abstract: This paper reports the design principles and evaluation results of a new experimental hybrid intrusion detection system (HIDS). This hybrid system combines the advantages of low false-positive rate of signature-based intrusion detection system (IDS) and the ability of anomaly detection system (ADS) to detect novel unknown attacks. By mining anomalous traffic episodes from Internet connections, we build an ADS that detects anomalies ....etc

Abstract

The demand for high-speed mobile wireless communications is rapidly growing.
OFDM technology promises to be a key technique for achieving the high data capacity and spectral efficiency requirements for wireless communication systems of the near future. This work presents an investigation into methods for maximizing the spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) systems. The current standards such as IEEE 802.11a in USA and ....etc

An Efficient and Fair Scheduling Scheme for
Multiuser OFDM Wireless Networks



Abstract

This paper proposes a new MAC scheduling scheme
for efficient support of multimedia services in multiuser OFDM
wireless networks, both in the uplink and in the downlink. This
scheme is based on a system of weights that dynamically accounts
for the experienced QoS and the transmission conditions in
an extended higher layers/MAC/PHY cross layer design.

Abstract

Comparative studies on DWT-OFDM and FFTOFDM systems are presented. The model for DWT-OFDM includes zero-padding and vector transpose for transmitting the OFDM signal. MATLAB simulation commands are also described. The discrete wavelet transform-OFDM (DWT-OFDM) has to satisfy the orthonormal bases and the perfect reconstruction properties to be considered as wavelet transform. Different wavelet families have been used and compared with the conventional ....etc

Abstract
Frequency offsets or frequency spreads distort theorthogonality between sub-carriers, which results in inter-carrierinterference (ICI), in regular OFDM communication systems. Inorder to combat the impact of ICI on OFDM systems, an ICImitigation technique by jointing symbol shift cancellation (SSC)and adjacent sub-channel interference filter (ASIF) is proposedin this paper. At first, the symbol shift cancellation (SSC) methodis used to cancel the impact of ICI on the far sub-carriers, andthen the adjacent sub-channel interferen ....etc

Segmentation of Pathological and Healthy tissues with Reduced Weighted vectors using Hybrid Intelligence Techniques
Abstract -- The proposed Method for automatic segmentation and detection of pathological tissues, normal tissues and CSF of human brain in Magnetic resonance image (MRI) is discussed in this paper. This method is implemented in two phases, (1) the MRI brain image is acquired from patient database, In that film artifact and noise are removed. (2) In second phase, hierarchal self organizing ....etc
