Wind Shear Detection with 802.11s Wireless Mesh Networking

摘要

A partial mesh array of wireless environmental sensors using IEEE 802.11s draft standard communications was developed for the detection of wind shear around airports. The system described here is self organizing, redundant and highly fault tolerant. It has no single point of failure and can continue operation even after a significant number of node failures. The objective of this system is to provide small and improvised airfields a system for detecting wind hazards as effective as those currently available only at much higher cost at the largest airports. The project is implemented with as much off-the-shelf hardware and software as possible. The goal was to rapidly develop a system with existing low cost components, avoiding significant development cost. This Redundant Array of Inexpensive Sensors (RAIS) [1] system uses XO computers developed by the One Laptop per Child (OLPC) Foundation as a hardware platform. A fully operating system was developed and tested. The results derived from testing are encouraging and clearly shows the viability of deploying such a system in the field.
