Abstract :
Design & Development of ´WINGSNET´ (WIRELESS INTELLIGENT GPS-BASED SENSOR NETWORK) System for monitoring Air Pollution (NO2, NO, O3, CO, CO2, SO2, PM10, PM25) and Radiation is based on WiFi and WiMAX Communication Network. WINGSNET System is designed to monitor Air Pollution and Radiation Nano-Sensors spread over geographical area. The Sensor-Units/Nodes (SU) are intelligent and smart enough to process the Sensor-Data and determine the Status as Normal, Alert or Alarm Condition and report the Sensors´ ID, Location, Status, Date/Time, etc. to the Reporting Station (RS), which may be mobile/stationary. The RS will transmit the status-information through a Base Station (BS) to a Centralized Monitoring Station (CMS). The CMS will display the Status of the Sensors for each Zone in real time and generate the Status-Report/Service-Report as required. The Sensors can be Stationary or Mobile and the Locations of the Stationary Sensors are pre-defined as Zone/Sub-Zone/X-Y Grid, while the Locations of the Mobile/Airborne Sensors are determined with the help of the WiFi Cell/WiMAX Cell/GPS System. The Sensor-Units, having low-power consumption, will be Solar-powered or Battery-based. A Messaging System/Format is defined for transmitting/receiving information between RS and CMS. A subset of WINGSNET can be configured as ´MAHAWIRG´ (MOBILE AD HOC ACCESS WIRELESS GPS-BASED) System, consisting of MSs (Mobile Stations) and BS (Base Station) as needed to monitor and support different Regions. The proposed WINGSNET/MAHAWIRG System is based onWiFi/WiMAX, having ´Broadband Wireless Technology´ and Bi-directional (Symmetric) Communication Links. The System has several Applications, such as transmitting and receiving Voice, Data, Messages, Graphs, Images, Video and Multimedia.
