Whitepaper: A Multilateral Secure Payment System for Wireless LAN Hotspots

by Springer Science+Business MediaJan 01, 2008

Beginning with the adoption of the de-facto standard for wireless LAN communications IEEE 802.11 in 1999 the research paper can observe a continuous growth of public wireless LAN hotspots that provide access to the Internet for modern road warriors. Unfortunately, current hotspots still suffer from several security drawbacks. This research paper analyses how payment schemes used in current hotspot architectures consider the security requirements of both hotspot providers and subscribers. It identify a conflict between subscribers’ wish for privacy and hotspot providers’ interest in prohibiting unlicensed (and thus unpaid) usage of the hotspot as the most challenging security objectives a future payment system has to fulfill.


Whitepaper: MAP: Medial Axis Based Geometric Routing in Sensor Networks

by Springer Science+Business MediaJan 01, 2008

This paper from Springer Science+Business Media shows that a compact and expressive concept of network connectivity by the medial axis enables efficient and localized routing. Medial axis of the network captures both the complex geometry and non-trivial topology of the sensor field. It can be represented succinctly by a graph whose size is in the order of the complexity of the geometric features (e.g., the number of holes). The paper focuses on routing in wireless sensor networks, where sensor nodes are stationary and deployed in a geometric space.


Whitepaper: Towards Next Generation CiteSeer: A Flexible Architecture for Digital Library Deployment

by Springer Science+Business MediaJan 01, 2008

This paper discusses about the first search engine for scientific literature to incorporate Autonomous Citation Indexing, and has since grown to be a well-used, open archive for computer and information science publications, currently indexing over 730,000 academic documents. It also presented a new version of the CiteSeer system, showing significant design improvements over its predecessor. However, CiteSeer faces significant challenges that must be overcome in order to improve the quality of the service and guarantee that Cite-Seer will continue to be a valuable, up-to-date resource well into the foreseeable future.


Whitepaper: A Scalable, Power-Efficient Broadcast Algorithm for Wireless Networks

by Springer Science+Business MediaJan 01, 2008

This white paper presents a scalable, power-efficient broadcast algorithm for wireless ad hoc networks. Initially the trade-off is investigated between reaching more nodes in a single hop using higher transmission power and reaching fewer nodes using lower transmission power and relaying messages through multiple hops. This white paper also presents BLSS, a scalable, fault tolerant and power-efficient broadcast algorithm for wireless ad hoc networks. Simulation results show that the performance of BLSS is comparable to that of BIP, a representative centralized algorithm and is superior to that of RBOP, a representative localized algorithm.


Whitepaper: Semantic Streams: A Framework for Composable Semantic Interpretation of Sensor Data

by Springer Science+Business MediaJan 01, 2008

This white paper showcases a framework called Semantic Streams that allows non technical users to pose queries over semantic interpretations of sensor data. The user can place constraints on values such as the amount of energy consumed or the confidence with which the vehicles are classified. This paper demonstrates how this system can be used on a network of video, magnetometer and infrared break beam sensors deployed in a parking garage with three simultaneous and independent users.


Whitepaper: Spatial Queries in Wireless Broadcast Systems

by Springer Science+Business MediaJan 01, 2008

Owing to the advent of wireless networking and personal digital devices, information systems in the era of mobile computing are expected to be able to handle a tremendous amount of traffic and service requests from the users. Wireless data broadcast, thanks to its high scalability, is particularly suitable for meeting such a challenge. Indexing techniques have been developed for wireless data broadcast systems in order to conserve the scarce power resources in mobile clients. This paper explores the scalability and mobility issues of supporting location-dependent spatial queries (LDSQs) in pervasive computing environments.


Whitepaper: SOA in the Real World - Experiences

by Springer Science+Business MediaJan 01, 2008

This paper published by Springer Science+Business Media describes the SOA architecture and asynchronous messaging that introduces fresh challenges in the area of integration testing and in testing the robustness of the system. To address these challenges, they built a tool called SOA Workbench. The paper also discusses the techniques adopted to address scenario-based validation that go beyond traditional document-centric validation based on XML Schema. Monitoring and error recovery, two key aspects of any mission-critical system, pose special challenges in a distributed SOA-based, asynchronous messaging setting.


Whitepaper: TulaFale: A Security Tool for Web Services

by Springer Science+Business MediaJan 01, 2008

Web services security specifications are typically expressed as a mixture of XML schemes, example messages, and narrative explanations. Web services specifications support SOAP-level security via a syntax for embedding cryptographic materials in SOAP messages. To meet their security goals, web services and their clients can construct and check security headers in messages, according to the WS-Security format. Web services may be vulnerable to many of the well-papered classes of attack on ordinary websites. This paper proposes a new specification language called TulaFale for writing complementary machine-checkable descriptions of SOAP-based security protocols and their properties.


Whitepaper: AOP for Dynamic Configuration and Management of Web Services

by Springer Science+Business MediaJan 01, 2008

Web service technologies accelerate application development by allowing the selection and integration of third-party web services, achieving high modularity, flexibility and configurability. However, current approaches only allow this integration by hard wiring the references to concrete web services into the client applications. Moreover they do not provide any management support, which is fundamental for achieving robustness. This paper identifies the requirements for this layer to realize the dynamic selection and integration of services, client-side management of services, and support for rules that govern the selection, integration and composition.


Whitepaper: Localized Algorithms for Energy Efficient Topology in Wireless Ad Hoc Networks

by Springer Science+Business MediaJan 01, 2008

Topology control in wireless networks is to select a sub graph of the communication graph (when all nodes use their maximum transmission range) with some properties for energy conservation. This paper from Kluwer Academic Publishers proposes two novel localized topology control methods for homogeneous wireless ad hoc networks. Topology control technique is to let each wireless device adjust its transmission range and select certain neighbors for communication, while maintaining structure that can support energy efficient routing and improve overall network performance.
