Wisenet - Complete ppt about the topic wisenet

  1. 1. WISENET Wireless Sensor Network 24-04-2014 Aboo Thahir 5th Sem BCA WISENET
  2. 2. Overview • Introduction • Design Goals • System Description • Software Components • Hardware Design • Power consumption • Applications • Future Scope • Conclusion 2
  3. 3. Introduction • What is Wisenet? Wisenet is a wireless network that monitors the environment conditions such as light, temperature and humidity. • What is “Motes”? This network is comprised of nodes called “motes” that form an ad-hoc network to transmit this data to a computer that function as a server. 3
  4. 4. Introduction How does Wisenet work? • The server stores the data in a database where it can later be retrieved and analysed via a web based interface. • The network works successfully with an implementation of sensor mote. 4
  5. 5. Introduction How does Wisenet Construct? • This involves selecting the hardware, designing the motes, and porting TinyOS. • Once the platform is completed and TinyOS was ported to it, the next stage is to use this platform to create a small-scale system of wireless network sensor. 5
  6. 6. Introduction Why we need Wisenet ? • Smart environment represent the next evolutionary development step in building, utilities, industrial, home, shipboard, and transportation systems automation. • The importance of sensor networks is highlighted by the number program, military program, and NSF program Announcements. • They may work in interior of a large machinery, at the bottom of an ocean, inside a twister, in a battlefield, in a home, in large building, or be attached to animals 6
  7. 7. Design Goals • Use of Commercial-Off-The-Shelf (COTS) software & standard interfaces where applicable – Apache web-server (HTTP) – MySQL database – PHP web programming language • Simple, web-based user interface • Battery-powered, wireless sensor nodes: 'motes' • Low-power consumption (Long battery life) • Motes create self-organizing ('ad-hoc') networks for robust communications 7
  8. 8. System Description There are two subsystems 1. Primary subsystems 1. Data Analysis 2. Data Acquisition 2. System Components 1. Client 2. Server 3. Sensor Mote Network 8
  9. 9. System Description • Primary subsystems 1. Data Analysis •This subsystem is Software-only •Relied on exist internet & Web infrastructure to provide communication between Client & Server components. •Selectively present collected environment data to End-user in a graphical manner 9
  10. 10. System Description • Primary subsystems 2. Data Acquisition • Collect & store environmental data for later processing by the Data analysis subsystem. • This is a Mix of both PC & embedded system software, as well as embedded system hardware. • It is composed of both server & Mote Network Components. 10
  11. 11. System Description • System Components 1. Client • Standard Web browser via Internet Any computer with a web browser and internet access could be a client. It served only as a user interface to the Data Analysis subsystem. 11
  12. 12. System Description • System Components 2. Server Critical component that link between the data Acquisition and Data Analysis subsystems. On the Data Analysis side is an HTTP server hosting a web application. When a page request comes in, the HTTP server calls the web application, which retrieves data from the SQL database, processes it, and returns a web-page which the HTTP server serves to the Client. 12
  13. 13. System Description • System Components 2. Server Web Program Flow 13
  14. 14. System Description • System Components 3. Sensor Motes It is the component responsible for collecting raw environmental data and transmitting that data to the Server. 14
  15. 15. System Description • System Block diagram 15
  16. 16. Software Components WISENET is also composed of three custom software components 1. Web program 2. WiseDB 3. TinyOS 16
  17. 17. Software Components 1. Web program • Written in PHP4 • Utilizes Charting Software: ChartDirector v3.0 • Generates 3 Graphs (default) • Passes Parameters via HTTP GET – Use bookmarks for specific queries • Retrieves Data for Specific Mote or All Motes 17
  18. 18. Web Program • Data Retrieval Form 18
  19. 19. Web Program • Generated Graphs 19
  20. 20. Software Components 2. WiseDB • Written in C++ • Utilizes open-source APIs • Application Programming Interfaces (API) • MySQL++ database API • Serial API • Relays information from mote network to database • Sends commands to mote network 20
  21. 21. Software Components 3. TinyOS • Real-time operating system for microcontrollers • Open-source project at UC Berkeley • Key Features: – Developed for sensing applications – Emphasis on low-power: Idle & sleep modes – Highly modular architecture – Efficient utilization of resources • Currently developed for Atmega microcontrollers 21
  22. 22. Hardware Design • Optimized 8051-core • Active (14.8 mA), Idle (29 _A) and sleep (0.2 _A) power modes • 32 kB flash memory • 2 kB +128 bytes SRAM • 5. Three channel 10-bit ADC • Four timers / Two PWM's • Hardware DES encryption/decryption • Hardware random bit-generator • Fully integrated UHF RF transceiver (433 MHz / 868 MHz nominal) 22
  23. 23. Applications •Lab / Office Monitoring •Habitat Monitoring •Security Applications •Extreme Weather Surveillance •Potential Biomedical Applications •Military Reconnaissance 23
  24. 24. Future Work • Expand network to develop & test multi-hop routing • Develop a single-board mote •Create a expandable, plug-in sensor interface • Research alternative energy sources •solar cell, rechargeable batteries • Continue development of TinyOs •Improve tools •Optimize performance/reduce power usage • Improve web interface •Data analysis 24
  25. 25. Power consumption • Sensor node lifetime shows a strong dependence on battery lifetime • Power consumption can be divided into: –Sensing –Communication –Processing 25
  26. 26. Conclusion •WISNET is smaller and faster •Emerging technology that will change the world •Many real-world applications •Low-power •Open-source software •Modular mote application design(TinyOS) •Flexible server implementation •Simple user interface via the web 26
