  2. Wireless Network System • Enables communication between two or more system . • Uses standard network protocols for communication. • Do not use network cabling Two types of network • Infrastructure Network • Ad-hoc Network

  3. Infrastructure Network

  4. Ad-Hoc Network

  5. Ad-hoc Network Application • Wireless Sensor Network. • Wireless Monitoring System is the results of the wireless sensor network. • What is Wireless Sensor Network? • Wireless network. • Consists of spatially distributed devices. • Uses sensors to monitor.

  6. Sensor Nodes • Considered as small Computers. • Consists Processing Unit with limited computational power. • Limited Memory. • Communication device Usually radio transceivers. • Power source in the form of battery.

  7. Benefits of Wireless Monitoring • Flexibility • Easier to upgrade and add new devices. • Eliminates the complexity of the system. • Cost • Reduced installation labor. • Easier to diagnose the efficiency of the process.

  8. Challenges of Wireless Monitoring • Security and Reliability • Authentication. • Encryption. • Integration with Existing Systems • Difficult to integrate with existing system. • Difficult to modify. • Battery Life • Tradeoff between power consumption and amount of data collected. • Alternative energy are also in research.

  9. Structural Health Monitoring • Wireless Monitoring is used to monitor the condition of the civil infrastructure. • An experiment was done by “Department of Civil Engineering, National Taiwan University, Taipei, Taiwan”. • Experimented with 3-story steel frame instrumented with wireless sensors for shaking table test.
