  3. 3. Wireless Sensor Networks (WSN) (General Introduction) <ul><li>A WSN is a wireless network consists of spatially distributed devices using sensors. </li></ul><ul><li>Sensors monitor the physical or environmental conditions at different locations, e.g. </li></ul><ul><ul><li>Temperature </li></ul></ul><ul><ul><li>Sound </li></ul></ul><ul><ul><li>Vibration </li></ul></ul><ul><ul><li>Pressure </li></ul></ul><ul><ul><li>Motion etc. </li></ul></ul><ul><li>Such networks are the key for gathering information in smart environments. </li></ul><ul><li>Some application areas are; </li></ul><ul><ul><li>Monitoring and Control Systems </li></ul></ul><ul><ul><li>Health care </li></ul></ul><ul><ul><li>Traffic control </li></ul></ul><ul><ul><li>Security </li></ul></ul><ul><ul><li>Home automation etc. </li></ul></ul>
  4. 4. Problem Statement <ul><li>Typically, a WSN performs distributed network computations to meet its specific needs. </li></ul><ul><li>Data received by sensors is processed with limited processing capabilities of a sensor node. </li></ul><ul><li>Complex network computations demand high processing power within a sensor node. </li></ul><ul><li>This results in high power consumption and affects network performance. </li></ul><ul><li>Issues: </li></ul><ul><li>- Low processing power </li></ul><ul><li>Battery consumption </li></ul><ul><li>Network performance </li></ul>
  5. 5. The Scientific Framework – 1/2 <ul><li>Collector nodes are introduced in [1]. </li></ul><ul><li>These nodes 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
  6. 6. The Scientific Framework – 2/2 (Role of Mobile Web Services) <ul><li>Collector nodes in the scientific framework 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>There is a chance to study new fields in the area of Mobile Web Services to identify realistic business and application scenarios. </li></ul><ul><li>The Scientific Challenges </li></ul><ul><li>In comparison to the network computations in fixed networks, the network computations in wireless networks is a scientific challenge. </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> Collector Node
  7. 7. Research Approach <ul><li>Study a real world background to identify actual needs and problems. </li></ul><ul><li>Focus on applications specified in RA B1 dealing with wireless communication in infrastructure-less environments. </li></ul><ul><li>Continued cooperation among the research assistants. </li></ul><ul><li>Longer lasting research goal shall be identified for the project. </li></ul><ul><li>Aim at contributing to network computation theory in WSNs in the long term. </li></ul><ul><li>Outcome of Research </li></ul><ul><li>Develop a solution for a real world problem e.g. Afghanistan project. </li></ul><ul><li>Contribution to the state-of-the-art distributed network computation theory of WSNs. </li></ul>
  8. 8. Value for UMIC <ul><li>Mobile multi-hop ad-hoc networks operate without pre-established infrastructure. </li></ul><ul><li>They are well suited for environments without communication infrastructure (RA B1 project). </li></ul><ul><li>How does it fit into UMIC? </li></ul><ul><li>The scientific goal is to study and develop generic mechanisms for complex distributed in-network computations based on Mobile Web Services involving; </li></ul><ul><ul><li>Mobile Web Services enabled collector nodes for WSN </li></ul></ul><ul><ul><li>Single service based computation </li></ul></ul><ul><ul><li>Cooperative services based computation (collector node cooperation) </li></ul></ul><ul><li>Outcome is expected in terms of: </li></ul><ul><ul><li>Optimized high-valued network performance and representation. </li></ul></ul><ul><ul><li>Low cost of battery consumption within sensor nodes. </li></ul></ul><ul><ul><li>Information access support in infrastructure-less environments. </li></ul></ul><ul><ul><li>Contribution to the scientific education and goals of UMIC. </li></ul></ul><ul><ul><li>Tight cooperation within UMIC researchers. </li></ul></ul><ul><ul><li>Contribution to the state-of-the-art network computation theory of WSNs. </li></ul></ul>
  9. 9. Summary <ul><li>The scientific framework is proposed that introduces the Mobile Web Services based collector nodes to perform distributed in-network computation for WSNs. </li></ul><ul><li>In comparison to the network computations in fixed networks, the network computation in wireless networks is a scientific challenge . </li></ul><ul><li>The collector node collaboration will produce higher-valued mobile web services . </li></ul><ul><li>Such services will represent the local neighborhood of sensors to some higher entity. </li></ul><ul><li>The scientific work will contribute to the state-of-the-art network computation theory of WSN in the long run. </li></ul><ul><li>Research focus shall aim a real world problem. </li></ul><ul><li>UMIC RA B1 project concerning wireless communication in infrastructure-less environments could be a good starting point. </li></ul><ul><li>Solutions for real world shall be developed, e.g. Afghanistan . </li></ul><ul><li>Longer lasting project goals and business/application areas shall be identified. </li></ul>
