In Wireless Parallel Multichannel data communication system using Selective Repeat Automatic Repeat Request protocol for Error Control Transmission. We assume the modified scheme for improve the performance of Data Transmission over Selective Repeat ARQ by adding SW ARQ protocol features. We evaluate the resequencing delay and the resequencing buffer occupancy, respectively. Under the assumptio...

This paper considers a robust decentralized H∞ control problem for uncertain multi-channel discrete-time descriptor systems with time-delay. The uncertainties are assumed to be time-invariant, norm-bounded, and exist in the system, time-delay and output matrices. Our interest is focused on dynamic output feedback. A sufficient condition for the uncertain multi-channel discrete-time descriptor s...

A model is proposed for a class of asynchronous sample-and-hold operators that relevant to the analysis embedded and networked systems. The parametrized by characteristics corresponding time-varying input–output delay. Uncertainty in relationship between timing zero-order-hold update events at output possibly aperiodic sampling input means delay does not always reset fixed value. This distinct ...

In a multi-hop cooperative communication scenario, where a transmitter can transmit a packet directly to the receiver or indirectly through a relay, there is an inherent trade-off between energy and delay. While it may consume more energy to transmit a packet directly to the receiver than transmitting through a relay, the transmission through relay incurs more delay. We consider the MAC layer o...

Abstract: This paper presents a delay-dependent approach to robust filtering for linear parameter-varying (LPV) systems with discrete and distributed time-invariant delays in the states and outputs. It is assumed that the state-space matrices affinely depend on parameters that are measurable in real-time. Some new parameter-dependent delay-dependent stability conditions are established in terms...

We propose a reaction-diffusion extension of a two species ecotoxicological model with time-delays proposed by Chattopadhyay et al (1997). Each species has the capacity to produce a substance toxic to its competitor, and a distributed time-delay is incorporated to model lags in the production of toxin. Additionally, nonlocal spatial effects are present because of the combination of delay and di...

This paper investigates the robust ∞ H sliding mode control problem for a class of uncertain switched delay systems. A single sliding surface is constructed such that the reduced-order equivalent sliding motion restricted to the sliding surface is completely invariant to all admissible uncertainties. For cases of known delay and unknown delay, the existence conditions of the sliding surface are...

This paper renders an optimal regulator for a system with state time-delay and quadratic performance index. First, by means of Maximum Principle and necessary optimal conditions, a continues-time two-point boundary-value problem (TPBVP) including both time-delay and time-advance is derived. Then, using Homotopy Perturbation Method (HPM), the obtained TPBVP is transformed into a sequence of line...

This paper deals with the global uniform exponential stability independent of delay of timedelay linear and time-invariant systems subject to point and distributed delays for the initial conditions being continuous real functions except possibly on a set of zero measure of bounded discontinuities. It is assumed that the delay-free system as well as an auxiliary one are globally uniformly expone...
