Pricing is an effective tool to control congestion and achieve quality of service (QoS) provisioning for multiple differentiated levels of service. In this paper, we consider the problem of pricing for congestion control in the case of a network of nodes under a single service class and multiple queues. We present a closed-loop multi-layered pricing scheme and propose an algorithm for finding t...

We study control of congestion in general topology communication networks within a fairly general mathematical framework that utilizes noncooperative game theory. We consider a broad class of cost functions, composed of pricing and utility functions, which capture various pricing schemes along with varying behavior and preferences for individual users. We prove the existence and uniqueness of a...

Recently a methodology for traac networks has been developed which extracts congestion toll sets such that the tolled user equilibrium is system optimal. Properties of toll sets, such as convexity, are investigated, as well as relationships with other problems. For a given toll set, various objectives can be deened and optimized with respect to the tolls. Examples include minimizing the total t...

Introduction In the early 1990's the power supply industries worldwide started to undergo a period of extensive changes. Electricity markets moved away from vertically integrated monopolies towards liberalized structures with power delivery being a bundle of several services mainly including generation, transmission and distribution. One reason for restructuring lied in the expectation that com...

The cordon pricing scheme is an efficient measure to untie congestion and environmental problems in urban metropolitan areas. Since March of 2007, Mashhad has implemented a restricted Central Business District (CBD) Zone as a seasonal congestion management program. The primary goal of the Mashhad cordon scheme is to reduce traffic congestion throughout the CBD. This paper describes the main fea...

THIS PAPER analyzes the pric ing of transit traffic in wireless peer-to-peer networks using the concepts of direct and indirect network externalities. We first establish that without any pricing mechanism, congestion externalities overwhelm other network effects in a wireless data network. We show that peering technology will mitigate the congestion and allow users to take advantage of more the...

The exponential growth of the Internet in virtually every metric has sparked a discussion about the role of pricing in public data networks. Initial research results demonstrate that priority pricing, congestion pricing, and other pricing schemes have the potential for improving social welfare over at-price schemes. While promising, these initial results have signi cant shortcomings that have l...

We study the role of pricing in packet-based telecommunication networks which use priorities to provide diierentiated Quality-of-Service (QoS). Customers are given the freedom to choose priorities, but are charged accordingly. Using a game theoretic framework, we study the case where customers choose an allocation of priorities to packets in order to optimize their net beneet. For the single li...

One of the most challenging issues of transmission grids in restructured power networks is determining the real transmission service cost. In this paper, a method for calculating the transmission service in different grids is presented. In the proposed method, the cost of power loss and congestion of transmission services are considered. Using this integrated model, the strengths and weaknesses...

Congestion cost allocation is an important issue in congestion management. This paper presents a genetic algorithm (GA) to determine the optimal generation levels in a deregulated market. The main issue is congestion in lines, which limits transfer capability of a system with available generation capacity. Nodal pricing method is used to determine locational marginal price (LMP) of each generat...
