چکیده

The problem of packet loss in wireless networks is considered and described in the paper. An introduction to the main causes of the problem are described first. Then the behaviour of different wireless protocols (Wlan, ZigBee, WirelessHART) is presented and described. Some possible techniques to reduce the effects of packets loss in a wirelessHART networked control system are analyzed in the last section.

Feature Extraction to Identify Network Traffic with Considering Packet Loss Effects

There are huge petitions of network traffic coming from various applications on Internet. In dealing with this volume of network traffic, network management plays a crucial rule. Traffic classification is a basic technique which is used by Internet service providers (ISP) to manage network resources and to guarantee Internet security. In addition, growing bandwidth usage, at one hand, and limit...

Design and Practical Implementation of a New Markov Model Predictive Controller for Variable Communication Packet Loss in Network Control Systems

The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...

THE STUDY OF PACKET LOSS EFFECT ON NETWORK CONTROL SYSTEM ERROR FUNCTION MODEL

Modern control systems widely use network to decrease the implementation cost and also increase the performance. Although they have several advantages, they suffer from some limitations and deficiencies. Packet loss is one of the main limitations which affect the control system in different conditions and finally can lead to system instability. To prevent such problems it is important to model ...

Research Overview

control is less reliable than wired control due to packet loss, time delay, and packet disorder caused by wireless communication. A Bernoulli random process was used to model the possible packet loss. A modi ed LQG control with a disturbance observer (DOB) was proposed to control the cRSEA under packet loss [1]. Under the situation when future references can be previewed, the preview control te...
