Distributed network protocols for anonymous stations in cooperative and noncooperative settings Politechnika Gdańska

INFORMATYKA

This work studies the effects of station anonymity and/or noncooperative (selfish) station behavior upon the design and performance of selected distributed network protocols. A set of stations interconnected by a computer network are assumed to be engaged in a collective activity for which some inter-station consistency is required. The considered protocols relate to group communication (where message delivery in agreed order is required), random multiple access over a single channel (where collision avoidance is required), and packet forwarding (where maintenance of end-to-end paths is required). Design of distributed protocols for anonymous stations permits to dispense with costly authentication mechanisms, and provides a "security lower bound" for systems in which station identities are relied upon. Modeling of noncooperative settings (where stations are allowed to behave selfishly) is justified in view of the increased autonomy and user configurability of today's network components; at the same time, as a departure from the traditional engineering paradigm, it opens up interesting areas of networking research. In Chapter 2, two agreed order multicast protocols are proposed for anonymous stations in a cooperative setting. Both are LAN-oriented i.e., designed to yield high group throughput by exploiting the natural synchronism of single-broadcast transmission media. A faulty communication environment is assumed with occasional reception misses - failures by one or more stations to receive a message. The Distributed Precedence Graph (DPG) protocol is network-independent in that multicast and reception primitives clearly define a protocol-to-network interface, and missed message recovery is separated from message ordering. In contrast, the Jamming Protocol (JP) is network-dependent and exploits in a novel way the "ideal synchronism" of LAN broadcast to couple missed message recovery and message ordering. Both proposed protocols are insensitive to membership control mechanisms and do without the knowledge of station identities. Even so, they compare favorably with existing agreed order multicast protocols like LANSIS or TOTEM, as demonstrated by the analysis of logicaltime properties and simulation of stochastic performance. Chapters 3 through 5 are devoted to game-theoretic analysis of random access MAC-layer protocols in a noncooperative setting. Chapter 3 deals with CSMA/CA, the multiple access mechanism of the IEEE 802.11 MAC protocol. It is argued that in an ad hoc wireless LAN, CSMA/CA is vulnerable to a selfish backoff attack consisting in systematic selection of short backoff times. Network performance under a backoff attack is evaluated via extension of Bianchi's Markovian approximation, as well as using more accurate models. A sufficient condition of solvability is given and a game-theoretic analysis is carried out with stations' bandwidth shares regarded as payoffs. Launching a backoff attack is established as a strictly dominating action, the payoff structure of the resulting one-shot CSMA/CA game being similar to a multiplayer Prisoners' Dilemma (with a unique and Pareto non-optmal Nash equilibrium). The notion of a Nash capacity is introduced to show that selfish station behavior reduces the achievable bandwidth utilization roughly by half compared with a cooperative setting. Incentive-based discouragement of backoff attacks is proposed in Chapter 4 using the concept of a repeated CSMA/CA game, where a station is allowed to reconfigure its CSMA/CA mechanism based upon past payoffs. Assuming that most stations are interested in enforcing cooperative behavior of the other stations, a satisfactory equilibrium play is shown possible. In particular, a selfish station can be expected to incline to honest play for fear of the other stations inclining to selfish play. This idea is elaborated upon and gives rise to two proposed strategies of playing the repeated CSMA/CA game, called Cooperation via Randomized Inclination to Selfish Play (CRISP) and Selfish Play to Elicit Live-and-Let-live (SPELL). By exploiting another property of the one-shot CSMA/CA game, called coarse profile observability, CRISP and SPELL are shown to asymptotically achieve Pareto optimality and the related Nash equilibrium becomes subgame perfect. It is shown how to extend the proposed strategies if some stations disengage the CSMA/CA backoff scheme. Chapter 4 concludeswith a discussion of QoS-sensitive station behavior, in which case the CSMA/CA game may change from a Prisoners' Dilemma into a form of a queuing game. Selfish behavior of CSMA/CA stations studied in Chapters 3 and 4 only affects specific protocol parameters, leaving the very principle of contention unchanged. In Chapter 5 we look at a slightly more general model of single-channel contention. In the proposed framework, the MAC protocol proceeds in cycles, each of which accommodates the stations' requests to transmit. This subsumes various existing random token-like protocols e.g., CSMA/CA, Random Token, slotted ALOHA, and HIPERLAN/1. A selection configuration determines how the requests are placed, whereas a winner policy decides the winner of a contention. It is argued that while the winner policy must be agreed upon by all the stations, the selection configuration is entirely within a station's discretion. For a wide class of winner policies, called Random Token with Extraneous Collision Detection (RT/ECD), the notions of verifiability and viability are introduced to factor out brute-force selfish behavior, and shown to lead to two interesting winner policies, RT/ECD-0 and RT/ECD--. The resulting games are found to be a multiplayer Prisoners' Dilemma and an anti-coordination game, respectively. Related repeated games are again found to potentially lead to cooperative behavior. In Chapter 6, selfishness considerations are extended to the network layer of a mobile ad hoc network (MANET). Each MANET station generates source packets and also is supposed to forward transit packets for pairs of stations currently out of each other's reception range. It is argued that forwarding transit packets becomes a dual liability: it shortens the station's battery life "in exchange for" sacrificing a portion of the channel bandwidth that could be used for source packets. Under the introduced packet anonymity model (no packet reveals its source station except at destination), undetectable selfish manipulation of the local congestion controls is possible. The issue is addressed in a noncooperative game-theoretic framework: each MANET station selects its own strategy (congestion control settings) at will, so as to maximize some defined payoff (a combination of source packet throughput and a reputation measure). For a class of Drop-and-Throttle (D&T) congestion control mechanisms, a generic model is formulated, whereby a station adjusts its D&T threshold in response to the other stations' adjusted thresholds; this model is subsequently translated into a simple extensive-form game. Types of reachable Nash equilibria are discussed and the notion of robustness of a Nash equilibrium is introduced. Finally, a novel packet forwarding protocol called Fair Forwarding with Forced Transmissions (F3T) is presented, which, if properly configured, leads to a desirable type of Nash equilibrium.

Front Office Manual Palgrave Macmillan

Książki / Literatura obcojęzyczna

Can you describe the rules for settling foreign exchange in Jordan? What is strange about the Australian swap market? What are IMM dates, and why do credit derivatives abuse them? Financial markets are exceedingly complex, often to their own detriment. The building blocks of finance are quite simple, however. Complexity arises when these building blocks are traded, combined, and modeled using a myriad of conventions, and using market knowledge which is obscure and hard for outsiders to discover. The Front Office Manual is a practical introduction to the front office, guiding readers through the functions and financial instruments commonly encountered in an investment banking business and importantly, how they work and are implemented in practice. The book begins with a guided tour of the front office, and of how a trade, the life-blood of all investment banks, actually works from inception, through its mid life-cycle events through to termination. The book also introduces the various market participants - investors, hedge funds, banks and asset managers to name but a few - with whom the front office interacts.Finally, the book describes the wide range of financial products used in trading and structuring, providing detail on the products themselves and the techniques needed to produce prices, estimate risk, and produce meaningful analysis. Throughout the book, the focus is on practical implementation, and 'how things are actually done in a banking environment', making this an invaluable working manual for newcomers to the industry, and those looking to move from a middle or back office function, or a different part of the financial community, to the investment banking front office.

Giotto and His Publics Harvard University Press

Książki / Literatura obcojęzyczna

This probing analysis of three works by Giotto and the patrons who commissioned them goes far beyond the cliches of Giotto as the founding figure of Western painting. It traces the interactions between Franciscan friars and powerful bankers, illuminating the complex interplay between mercantile wealth and the iconography of poverty. Political strife and religious faction lacerated fourteenth-century Italy. Giotto's commissions are best understood against the background of this social turmoil. They reflected the demands of his patrons, the requirements of the Franciscan Order, and the restlessly inventive genius of the painter. Julian Gardner examines this important period of Giotto's path-breaking career through works originally created for Franciscan churches: Stigmatization of Saint Francis from San Francesco at Pisa, now in the Louvre, the Bardi Chapel cycle of the Life of St. Francis in Santa Croce at Florence, and the frescoes of the crossing vault above the tomb of Saint Francis in the Lower Church of San Francesco at Assisi.These murals were executed during a twenty-year period when internal tensions divided the friars themselves and when the Order was confronted by a radical change of papal policy toward its defining vow of poverty. The Order had amassed great wealth and built ostentatious churches, alienating many Franciscans in the process and incurring the hostility of other Orders. Many elements in Giotto's frescoes, including references to St. Peter, Florentine politics, and church architecture, were included to satisfy patrons, redefine the figure of Francis, and celebrate the dominant group within the Franciscan brotherhood.
