Despite ten years of extensive research, M. Weiser's (1991) vision of ubiquitous computing is far from a widespread reality. While research into enabling technologies has progressed significantly, there has been a lack of research into the economic and commercial aspects of ubiquitous computing. We investigate techniques that will enable investors in ubiquitous computing infrastructure and services to recoup their investment through charging for service use. In particular, we identify the key requirements for a ubiquitous computing payment system, discuss existing payment systems and present the payment session protocol (PSP) that is designed to support payment-enabled ubiquitous computing environments.

As intelligent devices become affordable and wireless infrastructure becomes pervasive, the potential to combine, or aggregate, device functionality to provide a user with a better experience grows. Often, there will be multiple devices providing similar functionality that the user will have to choose from for the aggregation. We present the design and prototype implementation of a system for automatic selection of devices for aggregation in a dynamic environment. It allows a user to express trade-offs between the quality of device attributes, user distraction, and aggregation stability. This approach enables a user to have a richer experience without having to constantly worry about the device and the environment details.

Emerging ubiquitous and pervasive computing applications often need to know where things are physically located. To meet this need, many location-sensing systems have been developed, but none of the systems for the indoor environment have been widely adopted. We propose proximity mining, a new approach to build location information by mining sensor data. The proximity mining does not use geometric views for location modeling, but automatically discovers symbolic views by mining time series data from sensors which are placed in surroundings. We deal with trend curves representing time series sensor data, and use their topological characteristics to classify locations where the sensors are placed.

Ubiquitous computing embraces both nomadic computing and infrastructure-rich interactive workspaces. Although most effort in these areas to date has focused narrowly on one domain, there are interesting challenges at their intersection. To start a discussion on how some of the benefits of interactive workspaces can be provided to nomadic users, we present MeetingMachine, a digital media projector that incorporates both interactive workspace and nomadic computing technologies in an appliance form factor. As a research effort, the MeetingMachine attempts to bridge the gap between space-embedded and mobile computing models of ubiquitous computing, specifically focusing on the task of sharing information brought into and created during meetings. As a prototype artifact, the design of the MeetingMachine seeks to place ubiquitous computing technology into an appliance, whose role would be similar to that of a digital projector or conference room telephone.

Today car-navigation systems are increasingly penetrating the automotive market. However, the need for location-based information systems is no longer limited to cars. Mobile outdoor navigation systems for pedestrians and electronic tourist guides are already available on PDAs. In addition, new indoor positioning technologies extend the area of application for location-based systems. Unfortunately, current navigation systems are burdened by the fact that they are bound to a specific tracking technology (e.g., a car navigation system works exclusively with GPS) and therefore cannot be employed in areas with alternative tracking equipment. Furthermore, the information is provided through an abstract metaphor that the user has to understand and translate into action. We present a new augmented-reality-based paradigm and a framework for mobile navigation systems that pervasively extracts position and orientation information from any sensory source and enhances the association to the real world by combining video techniques and 3D-graphics in an augmented reality view.

Few real-world applications of mobile ad hoc networks have been developed or deployed outside the military environment, and no traces of actual node movement in a real ad hoc network have been available. We propose a novel commercial application of ad hoc networking, we describe and evaluate a multitier ad hoc network architecture and routing protocol for this system, and we document a new source of real mobility traces to support detailed simulation of ad hoc network applications on a large scale. The proposed system, which we call Ad Hoc City, is a multitier wireless ad hoc network routing architecture for general-purpose wide-area communication. The backbone network in this architecture is itself also a mobile multihop network, composed of wireless devices mounted on mobile fleets such as city buses or delivery vehicles. We evaluate our proposed design through simulation based on traces of the actual movement of the fleet of city buses in the Seattle, Washington metropolitan area, on their normal routes providing passenger bus service throughout the city.
在军事环境之外，已经开发或部署的移动自组织网络的实际应用很少，并且在实际的自组织网络中没有实际节点移动的痕迹。我们提出了一种新的自组织网络的商业应用，我们描述和评估了该系统的多层自组织网络架构和路由协议，我们记录了一个新的真实移动跟踪源，以支持大规模的自组织网络应用的详细模拟。该系统是一种面向通用广域通信的多层无线自组网路由体系结构，我们称之为Ad Hoc City。这种体系结构中的骨干网络本身也是一个移动多跳网络，由安装在移动车队(如城市公交车或送货车辆)上的无线设备组成。我们通过模拟华盛顿州西雅图市区的城市公交车队的实际运动轨迹来评估我们提出的设计，这些公交车队在整个城市的正常路线上提供客运巴士服务。

Applications and services in ubiquitous computing systems often interact in a context-dependent, reactive manner. How information flows, and what services communicate when, is determined by the context of the physical space, the context of users, and the services that are available. Existing discovery systems provide basic facilities for finding services based on their static descriptions in the form of attributes. Context-dependent attributes are not included in the service advertisements as they may in turn be computed and stored in other services. We propose an infrastructure, called River that provides various context-dependent, reactive communication primitives. These primitives are implemented using a single underlying technique called relational query based dispatching (RQD), which views the set of services in the system as a federation of databases, the discovery service as a distributed query processor for these databases, and communication as a combination of query processing and dispatching. We describe the design and implementation of the River infrastructure. We also show that the context-dependent query processing within the discovery service can actually reduce the lookup latency with little effect on overall throughput.

Many options exist for prototyping software-based human-computer interfaces, but there are few comparable technologies that allows application developers to create ad-hoc hardware interfaces with corresponding ease and flexibility. We present a system for rapidly constructing low cost prototypes of mobile input devices by leveraging wireless sensor nodes. We demonstrate two proof-of-concept applications: a conductor's baton and a scene navigation controller, that are prototyped using wireless sensor networks. These applications illustrate that wireless sensor technology can be used to quickly and inexpensively prototype diverse physical user interfaces. We believe that this technology will be of value in many areas, including the study of ergonomics, haptic interfaces, collaborative design, low-cost VR systems, and usability research.

It is useful to provide composers on mobile computers that dynamically compose the services offered by a set of networked devices. For example, a mobile computer could execute a multidevice composer that provides an operation for simultaneously turning off a set of lights rather than through their individual user-interfaces (UIs). We address the issue of flexibly and generically supporting multidevice composition. It makes the following novel contributions: (a) an identification of composition semantics that apply to a wide variety of devices, (b) a classification and evaluation of several existing mechanisms for supporting these semantics, and (c) an evaluation of a new composition framework that combines and extends existing, seemingly unrelated, approaches. The key to integrating these approaches is basing composition on programming patterns, which provide a bridge between the operation oriented and data oriented approaches. Our framework uses the existing ideas of allowing a single composer to work for a family of device classes and providing some composers that are based on UI generation. It extends these ideas by allowing a composer to be based on the programming patterns used in the device classes rather than the interfaces they implement to support all identified composition semantics.

Web services have started to appear on servers as interfaces between business-to-business applications. To date, mobile devices have only consumed Web services running on stationary servers. We expand this notion so that mobile devices can both offer and consume Web services. We discuss some interesting classes of applications that can be enabled when mobile devices can host Web services. This can be a powerful model for facilitating automatic interaction between resource-constrained mobile devices, time starved users, and pervasive infrastructure. We also explore the issues that arise due to mobility of devices hosting Web services, such as service discovery, device disambiguation, software footprint, and security requirements. To explore this paradigm and to gain an understanding of these issues, we have implemented a retail shopping scenario where a mobile device offers wallet services to an electronic check-out kiosk. This demonstration is now housed at the IBM Industry Solutions Lab and has been operational for several months.
