Game Theory in Communications

Vojislav Gajic

Multi-user communication theory typically studies the fundamental limits of communication systems, and considers communication schemes that approach or even achieve these limits. The functioning of many such schemes assumes that users always cooperate, eve ...

The Role of Game Theory in Key Agreement Over a Public Channel

Michael Christoph Gastpar

In this work we study the problem of key agreement over a public noiseless channel when Alice, Bob and Charlie observe discrete memoryless sources of an unknown distribution. Alice and Bob want to agree on a key K-AB that is protected from Charlie. At the ...

On Non-cooperative Location Privacy: A Game-theoretic Analysis

Jean-Pierre Hubaux, Julien Freudiger, David C. Parkes

In mobile networks, authentication is a required primitive of the majority of security protocols. However, an adversary can track the location of mobile nodes by monitoring pseudonyms used for authentication. A frequently proposed solution to protect locat ...

Spectrum Sharing Games of Infrastructure-Based Cognitive Radio Networks

Jean-Pierre Hubaux, Ghazale Hosseinabadi

The IEEE 802.22 standard is the first proposed standard for the cognitive radio networks in which a set of base stations (BSs) make opportunistic spectrum access to provide wireless access to the customer-premise equipments (CPE) within their cells in wire ...

On Wireless Social Community Networks

Jean-Pierre Hubaux, Mark Felegyhazi, Julien Freudiger, Peter Marbach

Wireless social community networks are emerging as a new alternative to provide wireless data access in urban areas. By relying on users in the network deployment, a wireless community can rapidly deploy a high-quality data access infrastructure in an inex ...

Game Theoretic Modeling of Malicious Users in Collaborative Networks

Georgios Theodorakopoulos

If a network is to operate successfully, its users need to collaborate. Collaboration takes the form of following a network protocol and involves some resource expenditure on the part of the user. Therefore, users cannot automatically be expected to follow ...

Non-cooperative behavior in wireless networks

Mark Felegyhazi

Existing cellular networks are centrally managed and require a tremendous initial investment. With the advancement of new wireless technologies, the operators of traditional networks have to face new competition. New technologies make it possible to provid ...

Malicious Users in Unstructured Networks

Georgios Theodorakopoulos

Unstructured networks (like ad-hoc or peer-to-peer networks) are networks without centralized control of their operation. Users make local decisions regarding whether to follow the network protocol or not. While providing scalability benefits, this degrade ...

Game Theory in Wireless Networks: A Tutorial

Jean-Pierre Hubaux, Mark Felegyhazi

The behavior of a given wireless station may affect the communication capabilities of a neighboring one, notably because the radio communication channel is usually shared in wireless networks. In this tutorial, we carefully explain how situations of this k ...

Nash Equilibria of Packet Forwarding Strategies in Wireless Ad Hoc Networks

Jean-Pierre Hubaux, Mark Felegyhazi, Levente Buttyan

In self-organizing ad hoc networks, all the networking functions rely on the contribution of the participants. As a basic example, nodes have to forward packets for each other in order to enable multi-hop communication. In recent years, incentive mechanism ...
