1. 788.11J Presentation “ Fire Wx Net ” Presented by Engy Ashraf Yehia

2. The Main Idea Provides the firefighting community the ability to safely, easily measure, view fire & weather conditions over a wide range of locations and elevations within forest fires. The designed system uses integrated a multi hop sensor network to provide environmental data integrated web-enabled surveillance cameras to provide visual data.

3. Fire Wx Net consisted of 5 long range links, 3 sensor networks consisting of a total of 13 nodes, 5 wireless access points, and 2 web cameras.

4. The Main Achievements built a system that successfully presented an elevational gradient of environmental conditions in wild land fire environments. This previously unattainable information will help fire behavior analysts make better predictions about fire conditions and create a ’more aware’ environment in the fire community, which will in turn help make fighting forest fires safer in the future.by using wireless technology &sensor networks

9. Pictures The Backhaul link set up on Boulder Peak. To the near side is an Access5830 with a directional antenna. On the far side is a M900S connected to a Yagi antenna. Below are two of the solar panels we used to provide power.

10. Pictures Figure 6: A block diagram of our weather network. The webcam, Soekris, and trango radio all con- nected to the switch via wired ethernet. The sensor node connected to the Soekris via a USB-to-serial cable.
