This paper addresses control design in networked control system by considering stochastic packet dropouts in the forward path of the control loop. The packet dropouts are modelled by mutually independent stochastic variables satisfying Bernoulli binary distribution. A sliding mode controller is utilized to overcome the adverse influences of stochastic packet dropouts in networked control system...

Various tools are available in market to measure packet loss in the end-to-end networks. But all the existing tools are not able to calculate packet loss in the network accurately. So measuring packet loss efficiently is still an open problem in the networks due to relatively occurrence and short duration of packet loss. The aim of our research is to understand how to efficiently calculate pack...

A crucial issue in optical packet switched (OPS) networks is packet losses at the network layer caused by contentions. This paper presents the network layer packet redundancy scheme (NLPRS), which is a novel approach to reduce the end-to-end data packet loss rate in OPS networks. By introducing redundancy packets in the OPS network, the NLPRS enables a possible reconstruction of data packets th...

This paper extends the modeling and analysis of packet switched multistage cube intercoimection networks to include the use of multiple-packet message formats. A multiplepacket message format is needed within an interconnection network when the message to be transmitted exceeds the network's packet size. The packet offset time is introduced and used to gauge the transmission rate differential b...

In this paper we have designed and developed ZigBee network in real time using ZigBee nodes to monitor risky parameters such as temperature, pressure, toxic gases and other chemical substances. Discussed about Wireless Sensor Network (WSN), ZigBee, ZigBee Network, Protocol stack and its various Applications. Derived various results from the network created. Various characteristics and network p...

An Ad Hoc network is an infrastructure less wireless network consisting of mobile moving nodes. In a network each mobile node act as a router as well as packet forwarder. Nodes in a Mobile Ad hoc Network (MANET) have limited battery power. Power consumption of network interfaces can be significant. In a MANET, if a mobile node continuously transmitting the data packets, more battery power consu...

Packet assembly at the network edge is one solution to reduce high packet rates in core network switches. Literature discusses this topic controversially because of three reasons: (1) potential negative impact of packet assembly on the traffic characteristics, (2) disruptive integration into existing networks and (3) lack of support of packet assembly in existing control plane environment. In t...

This paper details the development of an educational and research tool, the Network Performance Application (NetPerf), which provided real-time network performance measurement through simulated real-time data transmission over packet networks. This application is used to collect Quality of Service (QoS) statistics such as packet loss, end-to-end delay, interarrival delay jitter, and out-of-orde...
