چکیده

An important aspect of the Future Internet is the efficient utilization of (wireless) network resources. In order for the demanding in terms of QoS Future Internet services to be provided, the current trend is evolving towards an “integrated” wireless network access model that enables users to enjoy mobility, seamless access and high quality of service in an all-IP network on an “Anytime, Anywhere” basis. The term “integrated” is used to denote that the Future Internet wireless “last mile” is expected to comprise multiple heterogeneous geographically coexisting wireless networks, each having different capacity and coverage radius. The efficient management of the wireless access network resources is crucial due to their scarcity that renders wireless access a potential bottleneck for the provision of high quality services. In this paper we propose an auction mechanism for allocating the bandwidth of such a network so that efficiency is attained, i.e. social welfare is maximized. In particular, we propose an incentive-compatible, efficient auction-based mechanism of low computational complexity. We define a repeated game to address user utilities and incentives issues. Subsequently, we extend this mechanism so that it can also accommodate multicast sessions. We also analyze the computational complexity and message overhead of the proposed mechanism. We then show how user bids can be replaced from weights generated by the network and transform the auction to a cooperative mechanism capable of prioritizing certain classes of services and emulating DiffServ and time-of-day pricing schemes. The theoretical analysis is complemented by simulations that assess the proposed mechanisms properties and performance. We finally provide some concluding remarks and directions for future research.

Nous évoluons actuellement vers des réseaux d’accès sans fil intégrés qui doivent permettre la mobilité des utilisateurs, un accès transparent et une certaine qualité de service. Le terme "intégré signifie que les derniers sauts sans fil de l’Internet du futur comprendront plusieurs réseaux sans fil ayant des capacités et des zones de couverture hétérogènes. La gestion efficace des ressources de ces réseaux d’accès sans fil est cruciale étant donnée la limitation des ressources radios. Dans cet article, nous proposons un mécanisme basé sur la notion d’enchères pour allouer de la bande passante dans de tels réseaux. Avec ce mécanisme, l’efficacité est atteinte, i.e. le bien-être social est maximisé. Nous définissons une suite de tels jeux afin de prendre en compte les problèmes d’utilité des utilisateurs et d’incitation. Enfin, nous étendons ce mécanisme aux sessions multicast. Nous analysons aussi la complexité en calcul et les surcoût en terme de messages des mécanismes proposés. Enfin, nous montrons comment transformer l’enchère en un mécanisme coopératif capable de prioritiser certaines classes de services en remplaçant les paris des utilisateurs par des poids générés par le réseau. Pour finir, des simulations de ces mécanismes sont proposées. Mots-clés : rśeaux sans fil hétérogènes, allocation de bande passante, enchèresc Auction-based Bandwidth Allocation Mechanisms 3

A QoS-based charging and resource allocation framework for next generation wireless networks

Wireless networks are evolving to include Internet access to interactive multimedia and video conferencing as well as traditional services such as voice, email and web access. These new applications can demand large amounts of network resources, such as bandwidth, to achieve the highest levels of quality (e.g. picture quality). In conjunction with this trend, charging and resource allocation sy...

Auctioning of Link Capacity

The rapid growth of the Internet brings us two facts: increased requirements on large bandwidth and adequate supply of network resources by competitive network providers. New pricing mechanism is needed to satisfy both network users and providers by providing a fair and rational network usage mechanism. Auction is one of important ways for setting price according to demand and supply. How to in...

A simulation-based approach to bidding strategies for network resources in competitive wireless networks' 5th International Workshop on Internet Charging and QoS Technologies

We introduce a simulation-based approach to the problem that mobile users may face in a multi-provider environment when seeking to satisfy their demand for bandwidth; if they are allowed to satisfy their individual demands by aggregating shares from two or more providers the problem becomes one of resource allocation in a competitive market. We use the Progressive Second-Price auction at each p...

Auction Method and its Performance in a Dynamic Bandwidth Allocation Service

In leased line services used by ISPs (Internet Service Providers) the bandwidth is fixed, but the traffic changes dynamically. To address this, we propose an auction method for the dynamic allocation of bandwidth to ISPs sharing backbone networks. By the method, backbone networks can be used effectively as each ISP is able to secure bandwidth according to its own policy. The Internet users can ...
