Wireless self-organizing sensor networks are the topic of much ! current interest. One of the most difficult aspects to ! constrain with these networks is the efficacy of radio ! communications as a result of limited power. Most of the ongoing ! work in this arena has been built upon testing in relatively unobstructed environments, such as flat outdoor areas, and large ! indoor spaces. However, more real world environments ! that comprise of man-made of natural obstructions will cause the ! existing architectures - in the way they organize, share and/or ! gather information and do routing, to not perform optimally. - Preliminary results using 900 MHz radios indicate - that vegetation reduces the reliability of the - network to transmit data. - Here, we present the results of field experiments using the - Mica2 platfrom, an Atmel 128L microprocessor running - the Tiny Operating System (TinyOS) with 433 MHz radio. The network was deployed in Claremont Canyon, a wooded riparian environment --- 23,40 ---- ! Much of the previous work in this arena has in testing in relatively unobstructed environments, such as flat outdoor areas, and large ! indoor spaces. Real world environments, however, contain natural ! obstructions such as vegetation, and may be influenced ! by the topography of a site. Here, we present the results of ! field experiments using the Mica2 platfrom, an Atmel 128L ! microprocessor running the Tiny Operating System (TinyOS) ! with 433 MHz radio, and the Dust, Inc. "blue" using a 900 ! MHz radio. The statistics we are collecting include packet ! loss over distance, network initialization time and hop ! distribution. !

Notably, the ! canyon is the approximate northern boundary of the ! October 20, 1991 Tunnel Fire, the worst fire in the ! United States in terms of property and lives since the ! fire following the 1906 earthquake in San Francisco. ! The fire was stopped by a change in wind direction, ! fire conditions in the canyon remain largely those of 1991. ! |
