Welcome to the ACM SIGCOMM 2005 Workshops!.This year we are pleased to present a program of four excellent workshops: (1) Workshop on experimental approaches to wireless network design and analysis (E-WIND), (2) Workshops on economics of peer-to-peer systems (P2PECON), (3) Workshop on mining data networks (MineNet), and (4) Workshop on delay tolerant networking and related networks (WDTN).Workshops are becoming an integral part of the ACM SIGCOMM week-long Data Communications Festival and their goal is to enhance the ACM SIGCOMM conference technical program and promote cross-disciplinary interactions. In response to the call for proposals, we received a record of 12 workshop proposals, 4 of which were accepted after a review by the SIGCOMM 2005 organizing committee. Reaching out to other communities was probably one of the key factors in our selection process. E-WIND brings together the wireless and data networking communities; P2PECON has been successfully organized in the past two years as an independent workshop and brings together researchers from economics, distributed systems, and data networking; MineNet focuses on the analysis of the vast amount of data that can be extracted from the network and crosses the boundaries of networking, data mining, statistics, and machine learning. WDTN was selected as an emerging topic in data networking that could benefit from a focused workshop that will update researchers on the latest results in the area.There is a significant amount of logistics and co-ordination required between the four workshops and the ACM SIGCOMM 2005 conference and I would like to thank all the members of the SIGCOMM 2005 organizing committee and several volunteers who made it possible. First, I would like to thank Roch Guerin, Joe Touch, and Jennifer Rexford, for all their guidance during the workshop organization process and for being ready to assist at any time. Jaudelice C. de Oliveira and Honghui Lu managed the local arrangements. Steve Weber was always available to update the web-site with the workshop information, and Andreas Terzis and Christos Papadopoulos handled the registration and financial issues. Saswati Sarkar, and Lisa Tolles at Sheridan Printing led the difficult task of producing the combined proceedings.Last but not least, I would like to thank the organizers of the four workshops: Ed Knightly, Christophe Diot, Emin Gun Sirer, Eric Friedman, Shubhabrata Sen, Chuanyi Ji, Debanjan Saha, Joe McCloskey, S. Keshav, and Kevin Fall. Their hard work together with the excellent contributions of all authors were key in making these workshops successful.

Self-recharging virtual currency
Market-based control is attractive for networked computing utilities in which consumers compete for shared resources (computers, storage, network bandwidth). This paper proposes a new self-recharging virtual currency model as a common medium of exchange ...
Addressing strategic behavior in a deployed microeconomic resource allocator
While market-based systems have long been proposed as solutions for distributed resource allocation, few have been deployed for production use in real computer systems. Towards this end, we present our initial experience using Mirage, a microeconomic ...
An asynchronous and secure ascending peer-to-peer auction
In recent years, auctions have become a very popular price discovery mechanism. Among them, second-price auctions are of theoretical importance, as they have the simple dominant strategy of bidding ones true valuation. Sellers, however, are reluctant to ...
Influences on cooperation in BitTorrent communities
We collect BitTorrent usage data across multiple file-sharing communities and analyze the factors that affect users' cooperative behavior. We find evidence that the design of the BitTorrent protocol results in increased cooperative behavior over other ...
Incentives in BitTorrent induce free riding
We investigate the incentive mechanism of BitTorrent, which is a peer-to-peer file distribution system. As downloaders in BitTorrent are faced with the conflict between the eagerness to download and the unwillingness to upload, we relate this problem to ...
A new mechanism for the free-rider problem
The free-rider problem arises in the provisioning of public resources, when users of the resource have to contribute towards the cost of production. Selfish users may have a tendency to misrepresent preferences -- so as to minimize individual ...
Sybilproof reputation mechanisms
Due to the open, anonymous nature of many P2P networks, new identities - or sybils - may be created cheaply and in large numbers. Given a reputation system, a peer may attempt to falsely raise its reputation by creating fake links between its sybils. ...
Avoiding ballot stuffing in eBay-like reputation systems
We present a preliminary study on the robustness of binary feedback reputation systems (e.g. eBay) to ballot stuffing and bad mouthing. In a feedback based reputation system, a seller can collude with other buyers to undertake fake transactions in order ...
Fighting peer-to-peer SPAM and decoys with object reputation
Peer-to-peer filesharing is now commonplace and its traffic now dominates bandwidth consumption at many Internet peering points. Recent studies indicate that much of this filesharing activity involves corrupt and polluted files. This paper describes ...
Reputation-based pricing of P2P services
In the future peer-to-peer service oriented computing systems, maintaining a cooperative equilibrium is a non-trivial task. In the absence of Trusted Third Parties (TTP's) or verification authorities, rational service providers minimize their costs by ...
Reputation premiums in electronic peer-to-peer markets: analyzing textual feedback and network structure
Web-based systems that establish reputation are central to the viability of many electronic markets. We present theory that identifies the different dimensions of online reputation and characterizes their influence on the pricing power of sellers. We ...
