In the recent years use of Special Protection Schemes due to impact of notable these schemes in improving the performance of power systems has found increasing usage. The purpose of this paper is design a suitable and fast special protection schemes to deal with extreme contingency that will led to collapse of power network if they occurred. So at the first, for a clear form of power tran...
Traffic planning for multimedia has become more and more significant as new network infrastructures with different characteristics have been introduced lately. The increasing popularity of mobile communications has also drawn much of the attention from the research point of view. Thus, this paper addresses the problem of traffic planning, initiated by this interest, for mobile video communicati...
Wind and solar generators differ from conventional generators in their generation characteristics. The variable output and imperfect predictability of these generators face a stochastic approach to plan and operate the power system without fundamentally changing the operation and planning problems. This paper overviews stochastic modeling challenges in operations, generation planning, and trans...
The long-run incremental and marginal pricing are two different approaches for pricing transmission and distribution networks usage. The main difference between these two methods is to the way the cost of using the network is calculated. In the former approach, simulations are used, and in the latter, sensitivity analysis methods are used to determine the cost. In this paper, a novel analytical...

The increasing number of participants in modern mobile radio networks, especially with the prospect of the new CDMA systems, necessitates a more and more detailed and efficient radio network planning. The basis of network planning is always the prediction of the quality of transmission between the transmitter and the participant. In order to find the optimal location of the transmitters in a to...
In the cellular network with relays, the mobile station can benefit from both coverage extension and capacity enhancement. However, the operation complexity increases as the number of relays grows up. Furthermore, in the cellular network with cooperative relays, it is even more complex because of an increased dimension of signal-to-noise ratios (SNRs) formed in the cooperative wireless transmis...
In wireless sensor networks, the collected data are stored in the network nodes for a long time until the receivers take them. Since some network nodes may become accidentally corrupt or some mobile adversary intrudes to some node, data survival and secure and complete data transmission to some receiver is a concern. Moreover, we should consider communication efficiency and the needed store for...
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...
Since deregulation of the electric utility industry began in the USA, there has been a substantial increase in the quantity of power transferred over long distances. Both thermal and voltage constraints on transmission have been experienced in regions that previously were rarely congested. One solution to this type of problem is to expand the capacity of transmission networks, but it is likely ...
