In this paper we study the effect of communication nonidealities on the control of unstable stochastic linear systems. The communication protocol links the sensors to the actuators and should be studied by taking into account several limitations such as quantization errors, limited channel capacity, decoding delay and packet loss which, to the best of our knowledge, have not been considered joi...

Determining the perceived quality of packet audio under packet loss usually requires human-based Mean Opinion Score (MOS) listening tests. We propose a new MOS estimation method based on machine speech recognition. Its automated, machine-based nature facilitates real-time monitoring of transmission quality without the need to conduct time-consuming listening tests. Our evaluation of this new me...

In enormous and medium measured urban areas, transports have the accompanying elements: thickness directions, customary courses, predicable versatility, and so forth. In the multi-AP street organize, every transport knows other's predefined plans and settled courses.. In this paper, we try to performance enhancement of data delivery through improving the throughput and packet deliveryy ratio an...

ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. h...

The Objective Function (OF) can be used by the Routing protocol for low power lossy networks (RPL) to construct a Destination Oriented Directed Acyclic Graph (DODAG) based on routing metrics. standard OFs suffer from long hops when selecting route, which may cause consume node's energy faster. In this paper, we suggest an improvement of RPL OF that considers three results show proposed increase...

This contribution discusses the general problem of modelling packet loss distribution in IP networks, and is intended to provide input to Q.12 study of IP network behaviour and background material for the Q.8 and Q.16 groups. The factors that cause packet loss and packet discard within jitter buffers are generally transient in nature, typically related to congestion or link failure. This leads ...

The Early Packet Discard (EPD) with per-VC Queueing mechanism is a packet discard scheme proposed in the literature to improve EPD performance in terms of fairness. This paper develops an analytical approximation model for evaluating the performance of the mechanism at a single node. As illustrated in the paper by numerical examples, the model allows the study of the evolution of performance me...

We present m-limited forwarding, a technique to reduce the cost of disseminating information in a power-constrained environment by limiting the cardinality of the subset of nodes which retransmit a packet. We show how this technique can be used to improve the performance of ad hoc routing protocols. m-AODV applies m-limited forwarding to the AODV routing protocol, and is used for networks with ...
