The Personal Router Whitepaper	whitepaper	March-2000	An overview of the personal router project including motivation, research challenges, technology, and initial design.
Expressing Application and Network Adaptivity: Time Variations and Adaptation Paths	thesis	February-2001	Traditional QoS parameters often poorly match user preceived notions of quality in wireless networks. This research therefore examines two qos parameters that characterize application and network service requirements and capabilities. These parameters enables the translation of user perceived notions of application utility into appropriate network service selections and controls. In particular the application utility specifications capture important time constraints and adaptation paths that have not been adequately expressed previously. We demonstrate the benefits of our model by showing how applications and wireless networks can improve the quality of service delivered.
Designing Traffic Profiles for Bursty Internet Traffic	technical report	June-2001	This paper proposes a new class of traffic profiles that is better suited for metering bursty Internet traffic streams that the traditional token bucket profile. Our traffic profiles decouple the long term average rate control from the burst size control. Compared to a token bucket profile this profile improves the level of QoS for conforming traffic yet limits the "effective bandwidth" consumed by a non-conforming traffic stream.
Primitive-Based Payment Systems for Flexible Value Transfer in the Personal Router	thesis	June-2002	This thesis explores a new method for payment systems based on component building blocks. Payment systems are split into primitive operations; each of them implementing one step of a payment transaction. The combination of building blocks represents a payment protocol in which a buyer and seller of wireless services engages. This flexible approach enables a variety of provider and consumer payment methods.

AI in Wireless Networks: The Personal Router Agent for Wireless Access	paper	August-2002	This paper describes an AI approach to the PR user modeling problem using reinforcement learning.
The Personal Router: An Agent for Wireless Access	paper	August-2002	This paper presents a description and formal model of user modeling in the PR. This was presented at the AAAI 2002 Fall Symposium.
Designing Traffic Profiles for Bursty Internet Traffic	paper	November-2002	This is a slightly shorter version of the tech report of the same name. This paper proposes a new class of traffic profiles that is better suited for metering bursty Internet traffic streams that the traditional token bucket profile. Our traffic profiles decouple the long term average rate control from the burst size control. Compared to a token bucket profile this profile improves the level of QoS for conforming traffic yet limits the "effective bandwidth" consumed by a non-conforming traffic stream
Residential Resale of Wireline Broadband via Wireless	thesis	February-2003	This thesis examines the market oppurtunties in the US and Europe for resale of broadband network service via wireless. We present a cost model to evaluate the circumstances under which such resale maybe profitable for wireline carriers.
Social Agents for Dynamic Access to Wireless Networks	paper	March-2003	This paper presents some methods for solving the general MDP model presented in the paper "The Personal Router: An Agent for Wireless Access". This was presented at the AAAI 2003 Spring Symposium.
QoS Assurance with Collocated Wireless Access Points	thesis	May-2003	This research considers the problem of automatically configuring networks of 802.11 access points (APs) that share common physical spaces. The challenge is to find channel assignments for collocated APs that maximize the global network capacity and satisfy local service demands. The solution must satisfy the capacity constraints of the wireless spectrum and quickly converge to a stable and robust configuration under dynamic network conditions and varying service loads.
An Auction-based Method for Shared Wireless Medium Access Control	thesis	June-2003	This thesis presents a design and implementation of a wireless allocation system that uses pricing and a bid-auction process to arbitrate access to a shared wireless channel. It may be used within an arbitration framework where users agree on a protocol for shared access to spectrum.
Dynamic Self-Configuration of Collocated Wireless Networks	poster abstract	August-2003	Sigcomm 2003 poster abstract
Automatic Service Selection in Dynamic Wireless Environments	poster	September-2003	This is a poster that was presented at Mobicom 2003.
Automatic Service Selection in Dynamic Wireless Network Environments	Poster Abstract	September-2003	This is the abstract of the poster presented at Mobicom 2003 detailing our work on automatic service selection in dynamic wireless environments.
A User-Guided Cognitive Agent for Network Service Selection in Pervasive Computing Environments	paper	March-2004	This paper was presented at Pervasive Computing in March 2004. It presents results from a preliminary user experiments that demonstrate the effectiveness of the agent which learns users preferences for wireless services.
Learning User Preferences for Wireless Services Provisioning	poster	July-2004	This paper was presented at AAMAS in July of 2004. It addresses both the artificial intelligence and economic [mechanism design] problem of the personal router system.
