problems of transport protocols in satellite IP networks along with the most recent solutions proposed in the literature. Non-real-time applications use Transmission Control Protocol (TCP). Current TCP schemes have throughput problems in networks with long propagation delays and relatively high link error rates such as satellite networks [1]. TCP throughput decreases mostly because: • The long ...

Networked control systems (NCSs) are a type of distributed control systems, where the information of control system components (reference input, plant output, control input, etc.) is exchanged via communication networks. Due to the introduction of networks, NCSs have many attractive advantages, such as reduced system wiring, low weight and space, ease of system diagnosis and maintenance, and in...

This paper presents a mathematical model and a methodology to analyze the losses in transmission expansion planning (TEP) under uncertainty in demand. The methodology is based on discrete particle swarm optimization (DPSO). DPSO is a useful and powerful stochastic evolutionary algorithm to solve the large-scale, discrete and nonlinear optimization problems like TEP. The effectiveness of the pro...

The optimization is one of the challenging problems in power system. The optimization sometimes is mainly restricted to the minimization of the operating cost. However, the operation of power plants, mostly thermal units, results into various types of emissions like SOx, NOx and COx etc. The environmental concern dictates the minimization of the emissions by the thermal plant. Individually, if ...

The reliable transmission of compressed images across noisy transmission channels and networks prone to packet losses is considered. The problem is viewed from a source coding perspective, where the main constraints are maximum coding efficiency and minimum redundancy. Error-resilient mechanisms are incorporated into wavelet-based image encoding schemes to obtain robust data streams that withst...

In this paper, we present the concept of transmitting power without using wires i.e., transmitting power as microwaves from one place to another is in order to reduce the transmission and distribution losses. This concept is known as Microwave Power transmission (MPT). We also discussed the technological developments in Wireless Power Transmission (WPT). The advantages, disadvantages, biologica...

This paper has presented the different data transmission limitations in radio over fiber communication systems such as total losses and fiber dispersion. These limitations can be solved by Soliton transmission technique. Signal to noise ratio, bit error rate, and optical signal to noise ratio can be investigated. The transmission bit rate per channel can be analyzed with using both space divisi...

TCP performs reasonably well over the Internet where packet losses are mainly due to network congestion. However, TCP suffers significant throughput degradation over hybrid wireless/IP networks where packet losses are also due to transmission errors in wireless segments and during mobile host handovers. In this paper, the micro-scale behavior and packet-level performance of four popular TCP var...

Security of the "ping-pong" quantum communication protocol recently proposed by Boström and Felbinger [Phys. Rev. Lett. 89, 187902 (2002)]] is analyzed in the case of considerable quantum channel losses. The eavesdropping scheme is presented, which reveals that the ping-pong protocol is not secure for transmission efficiencies lower than 60%. Our scheme induces 50% losses, which, however, can b...

In this study, we investigate the transparency of an overdense inhomogeneous plasma slab. This anomalous transmission is achieved when the conditions provided for the incident electromagnetic wave to excite coupled surface waves on the both sides of the slab. These conditions require that the homogeneous overdense plasma, or the metallic film, is placed between two dielectric layers. Here, the ...
