this paper introduces the application of wave variable method in reducing the effect of delay during the transmission of control signals via large distances in a multimachine power system. Fast response and pure control signals applied to a power system have great importance in control process. At first we design a centralized optimal control considering no transport delay and then we compare t...

Recovery of data packets from packet erasures in a timely manner is critical for many streaming applications. An early paper by Martinian and Sundberg introduced a framework for streaming codes and designed rate-optimal codes that permit delay-constrained recovery from an erasure burst of length up to B. A recent work by Badr et al. extended this result and introduced a sliding-window channel m...

It is well established that increased network transmission speed reduces the e€ectiveness of feedback-based adaptive rate control mechanisms, due to the increased bandwidth propagation delay product. In this environment, di€erences in the propagation delays associated with the controlled sources become larger when measured in slots (transmission time of information unit), potentially inducing s...

It is well known that the stability and performance of a networked control system (NCS) are strongly affected by the transmission delay, which is usually random in communication networks such as Ethernet. In order to cope with the random transmission delay and increase the control performance, a novel switching control approach for NCS is proposed. The random transmission delay is modelled by a...

We present an event-triggered control strategy for stabilizing a scalar, continuous-time, time-invariant, linear system over a digital communication channel having bounded delay, and in the presence of bounded system disturbance. We propose an encoding-decoding scheme, and determine lower bounds on the packet size and on the information transmission rate which are sufficient for stabilization. ...

As the operating frequency increases to Giga Hertz and the rise time of a signal is less than or comparable to the time-of-flight delay of a line, it is necessary to consider the transmission line behavior for delay computation. We present in this paper an analytical formula for the delay computation under the transmission line model. Extensive simulations with SPICE show the high fidelity of t...

Selective-Repeat ARQ (Automatic Repeat reQuest) protocol is the most efficient error control technology in wireless because it allows the transmitter to retransmit only negatively acknowledges (NACK) packets. In this paper, by analyzing the transmission mechanism of SR-ARQ, the discrete-time Geom/G/1/ queue model is established sententiously based on equivalent delay under the condition that th...

Many real-time applications use Internet as a media to transmit their data and need guarantee for correct data transmission and limited transmission delay. It requires efficient network traffic protocols to avoid or limit the level of congestion. In this paper we propose, design and analyze a Robust Delay Based Controller (RDBC) for traffic management on transmission control protocol (TCP). Thi...

The number of Internet users is increasing quickly with the transmission of voice over IP. Therefore provision of fast transmission without jitter and delay is the fundamental aspect of voice communication. This study evaluates the performance of SCTP and TCP in transmission of voice packets. Generally, when packets are arrived at destination, these are probably affected by jitter. Many researc...

This paper is concerned with the stability analysis of networked control systems (NCSs) with random delays in the control loop. The time delay between sensor and controller is modeled as a Markov process, the time delay between controller and actuator is assumed constant. A sampled-data system approach is considered. We assume that the controller is able to monitor the transmission delay which ...
