Observer-based Control Design and Stability Analysis of Networked Hammerstein Systems
Abstract: In this paper, an attempt has been made to design observer for Networked Control System (NCS) with random delays. The NCS has been modeled as a Hammerstein system, a cascade combination of static non-linearity and LTI system. Luenberger Observer and Kalman Filter have been used to estimate the system states. Simulation results have been presented which result in stable overall Hammerstein systems, with improvements over existing control procedures.Keywords: Networked Control …

Call Admission Control in ATM Networks using Interval Arithmetic CEN
Abstract: Call admission control (CAC) is one of the most fundamental preventive congestion control mechanisms in asynchronous transfer mode (ATM) networks. Call admission control is further complicated by the diverse mix of traffic types and service requirements and by the increasing speed of transmission. In this project, the focus is on a call admission control with interval arithmetic coulomb energy network, a generalization of coulomb energy network (CEN), which can handle …

A Comparative Analysis of Attacks in Wireless Network
Abstract: Sensor networks (WSN) is an emerging technology and a hot research topic among researchers due to their flexibility and independence of network infrastructures, such as base stations. It can also be used for applications such as building, traffic surveillance, and habitat monitoring and many scenarios. It is flexible to go through physical partition and it avoids lot of wiring. The major challenges one facing today in wireless sensor network is …

Video Steganography System using Chua Circuit for Data Encryption
Abstract: Data transmitted over the Internet is becoming more and more prone to hacking. Therefore, network security has become key concern for everyone. Over the years cryptography and steganography has evolved as two branches of information security. The paper combines chaotic cryptography and video steganography to provide a two tiered protection for the message to be transmitted over any network. The message is first encrypted and made unrecognizable using Chua cryptography. …
