In hierarchical reliable multicast schemes, the number of repair proxies and their locations influence the delivery delay. Low delivery delay is essential for the transmission of real time media. In this paper, we propose a method to decide optimal locations of repair proxies that minimizes the mean delivery delay of all receivers in heterogeneous network using a dynamic programming approach. T...

A new Markov-based method for real time prediction of network transmission time delays is introduced. The method considers a Multi-Layer Perceptron (MLP) neural model for the transmission network, where the number of neurons in the input layer is minimized so that the required calculations are reduced and the method can be implemented in the real-time. For this purpose, the Markov process order...

Internet Traffic has grown exponentially over last few years due to provision of multiple class services through Internet backbone. With the explosive use of Internet, contemporary Internet routers are susceptible to overloads and their services deteriorate drastically and often cause denial of services. In this paper, an analysis is made how forecasting technique, routing algorithm and Genetic...

In the low duty cycle wireless sensor network with unreliable link quality, how to meet designated delay requirements and maximize network lifetime is the focus of this study. This paper proposes the Scheduling Scheme based on Estimated-delay(SSE), which could satisfy decreasing energy consumption as well as delivery delay in the low duty cycle wireless sensor network by utilizing the estimated...

This work is devoted to integrated controlscheduling in the case of real-time control of systems with communications delays, i.e. network induced delay and input output latency. Feedback control of computing resources is tackled, to deal with CPU resource variations and unpredicitble workload. Thus two new control schemes are provided for feedack scheduling of single and multi control task syst...

Introduction: In this study, the effect of memantine administration into the nucleus accumbens on the metabolic changes induced by acute stress in female mice was evaluated. Methods: Intra-accumbens unilateral or bilateral canulation was performed. One week after recovery, a group of animals were given memantine (1, 0.5, and 0.1 μg/mouse) five min before stress induction intra-accumbally, an...

This paper has proposed a controller design method for networked control systems with network induced delays by using LMI-based delay-dependent optimization. The delays are described by a Markov chain, since they are to be time-varying and even longer than the sampling time. A delay-dependent compensation method has been proposed here with a jump linear system analysis technique to stabilize th...

Abstract: This paper is concerned with the design of networked control systems based on multi-rata technique. Firstly, based on the Fourier series of periodic signal, a novel nonlinear two part periodic function (NTPPF) method is proposed to construct the generalized sampled-data hold function (GSHF). Secondly, a hybrid nonlinear delay system model is constructed by establishing the relationshi...

Random Early Detection (RED) is one of the most commonly used Active Queue Management (AQM) algorithms that is recommended by IETF for deployment in the network. Although RED provides low average queuing delay and high throughput at the same time, but effectiveness of RED is highly sensitive to the RED parameters setting. As network condition varies largely, setting RED's parameters with fixed ...

We develop an approach to the analysis of average queueing delay in a tree network of discrete-time queues with constant senice time. The analysis of such systems is pertinent to packet-switehed data networks with fixed-length packets. Our solution is based on considering an equivalent network, in which at each node packets in transit are given priority over exogenous arrivals. The solution to ...
