Transcript of "Mobile Web Services for Distributed In-Network Communications and Computations - OVERVIEW"

  1. 1. Mobile Web Services for Distributed In-Network Communications and Computations - OVERVIEW <ul><li>Motivation </li></ul><ul><li>Typically, a WSN performs distributed network computations to meet its specific needs. </li></ul><ul><li>Complex network computations demand high processing power within a sensor node. </li></ul><ul><li>Collector nodes introduced in [1] are better equipped in terms of processing power and battery consumption than ordinary sensors. </li></ul><ul><li>High-valued distributed in-network computations can be achieved by collector nodes‘ collaboration . </li></ul><ul><li>Collector nodes represent local neighborhood of sensors to higher hierarchy of WSN. </li></ul>Sensor and Collector nodes could be mobile terminals [1] Giridhar, A. Kumar, P.R., Toward a theory of in-network computation in wireless sensor networks , Communications Magazine, IEEE , Volume 44, Issue 4, p. 98- 107, ISSN: 0163-6804, 2006 <ul><li>Proposed Solution </li></ul><ul><li>Collector nodes are proposed to apply Mobile Web Services to perform local computations . </li></ul><ul><li>Cooperation among the collector nodes would initiate higher-valued Mobile Web Services for complex distributed in-network computations. </li></ul><ul><li>Study new fields in the area of Mobile Web Services to identify realistic business and application scenarios . </li></ul><ul><li>Scientific Challenges </li></ul><ul><li>Network computations in wireless networks. </li></ul><ul><li>Organization of cooperative collector nodes owning Mobile Web Services. </li></ul><ul><li>Gain a high-valued network based on Mobile Web Services. </li></ul>Issues: Low processing power, Battery consumption, Network performance Prof. Dr.-Ing. B. Walke, Fahad Aijaz Chair of Communication Networks
  2. 2. Research Outcomes <ul><li>What‘s New </li></ul><ul><li>Transition from tranditional short-lived (synchronous) to long-lived (asynchronous) highly dynamic Mobile Web Services. </li></ul><ul><li>Mobile Web Services framework for development and deployment of P2P asynchronous time-independent services . </li></ul><ul><li>Supports Polling and Callback interaction techniques. </li></ul><ul><li>Dynamic (run-time) service management in terms of Control and Monitoring. </li></ul><ul><li>Facilitates P2P service composition and collaboration (also basis workflows and transactions oriented use cases). </li></ul><ul><li>Bluetooth binding for Mobile Web Services. </li></ul><ul><li>Prototypes of In-Network Computation and Mobile Gateway. </li></ul><ul><li>Publications </li></ul><ul><li>JOURNAL: Gehlen, G. and Aijaz, F. and Yi Zhu, and Walke, B., Mobile P2P Web Services using SIP .
