January 2012 Telecommunication Economics: selected results of the COST action IS0605 [email protected]
Publisher: Springer-Verlag
Bibliometrics:
Citation Count: 1

This section deals with the network neutrality debate to define the economic relationships between Internet access providers and (distant) content providers. We review the various definitions of what should be a neutral network, the outcome of all international consultations on the topic, and the arguments of network neutrality proponents and ...

November 2011 GameSec'11: Proceedings of the Second international conference on Decision and Game Theory for Security
Publisher: Springer-Verlag
Bibliometrics:
Citation Count: 0

Network users can choose among different security solutions to protect their data. Those solutions are offered by competing providers, with possibly different performance and price levels. In this paper, we model the interactions among users as a noncooperative game, with a negative externality coming from the fact that attackers target ...

The economic stakes of advertising on the Internet - and in particular, of auctions for keywords in search engines- are enormous and still increasing. We focus in this paper on situations where bidders (advertisers) on sponsored search auction systems have a limited budget, so that they may not be able ...

July 2011 MASCOTS '11: Proceedings of the 2011 IEEE 19th Annual International Symposium on Modelling, Analysis, and Simulation of Computer and Telecommunication Systems

Citation Count: 1

Search engines are essential actors for web browsing. We analyze here the economic competition between search engines earning money from ad word auctions. We develop a two-level game where at the largest time scale search engines decide which allocation rule to implement, between revenue-based and bid-based, and at the lowest ...

Telecommunication networks are now an interconnection of competitive operators that need to cooperate to ensure end-to-end delivery of traffic. Inter-domain agreements have to be performed, and pricing is seen as a relevant way to provide an incentive to intermediate domains for forwarding the traffic of others. In this paper, we ...

Search engines get revenue thanks to ad word auctions, where commercial links are proposed and charged to advertisers as soon as the link is clicked through. Most search engines have chosen (or switched to) a revenue-based ranking and charging scheme instead of a bid-based one. We investigate here the relevance ...

With the development of new technologies in a competitive context, infrastructure investment and licence purchase as well as existing technology maintenance are crucial questions for current and emerging operators. This paper presents a three-level game analysing this problem. At the highest level, the operators decide on which technologies to invest, ...

Citation Count: 3

Wireless users have the opportunity to choose between heterogeneous access modes, such as 3G, WiFi or WiMAX for instance, which operate with different distance ranges. Due to the increasing commercial interest in access networks, those technologies are often managed by competing providers. The goal of this paper is to study ...

The asymptotic robustness of estimators as a function of a rarity parameter, in the context of rare-event simulation, is often qualified by properties such as bounded relative error (BRE) and logarithmic efficiency (LE), also called asymptotic optimality. However, these properties do not suffice to ensure that moments of order higher ...

Randomized quasi-Monte Carlo (RQMC) methods estimate the expectation of a random variable by the average of n dependent realizations of it. In general, due to the strong dependence, the estimation error may not obey a central limit theorem. Analysis of RQMC methods have so far focused mostly on the convergence ...

Citation Count: 6

In 3G wireless technologies, competitive operators are assigned a fixed part of the spectrum from long-term auctions. This is known to lead to utilization inefficiencies because some providers can be congested while others are lightly used. Moreover it forbids the entrance of new candidate providers. There is now a stream ...

Modeling the competition among telecommunication operators (or providers) as a repeated game may explain why tacit collusion to maintain high charging prices can be observed. Such outcomes clearly do not benefit the users, nor do they provide operators with incentives to improve the network quality of service to outperform their ...

Network operators are merging their services, such as fixed or wireless telephony, internet or television, into single offers, called bundles. It is essential to understand consumers' preferences to define the most profitable bundles, with their associated prices, especially in the fierce competitive current market. We start by defining a random ...

With the rapid development of wireless Internet services, several WLAN service providers may coexist in one public hotspot to compete for the same group of customers, leading to an inevitable price competition. The charged price and the provisioned packet loss at each provider are major factors in determining users' demands ...

Citation Count: 1

Radio spectrum allocation is essential to the provision of mobile communication services. The spectrum is a finite resource and can accomodate a limited number of simultaneous users at one time. Due to this scarcity, allocating traditional mobile licenses to new mobile operators is unrealizable and new entrants should bargain access ...

Competition among providers has become an important issue in current and future wireless telecommunication networks. The providers may operate using different technologies, such as WiFi, WiMAX, UMTS... In a previous work, we have analyzed the price competition among two providers, one operating in only a subdomain of the other, due ...

In a probabilistic model, a rare event is an event with a very small probability of occurrence. The forecasting of rare events is a formidable task but is important in many areas. For instance a catastrophic failure in a transport system or in a nuclear power plant, the failure of ...

The IEEE 802.16 standard is expected to become a successful broadband wireless access solution, especially thanks to its ablility to provide high data rates, to differentiate services, and thanks to its interoperability, as promoted by the Worldwide Interoperability for Microwave Access (WiMAX) organization. We consider in this paper an Orthogonal ...
