1. “Sensor Flock” An Airborne Wireless Sensor Network of Micro-Air Vehicles Presented by: Ahmed ezz-eldin

2. The Main Idea High granularity atmospheric sensing of toxic plume behavior.

3. The Main Achievements 1-An airborne WSN composed of hundreds of small size, inexpensive, semi-autonomous, and cooperating bird- sized micro aerial vehicles (MAVs). 2-Sense and relay data over a wireless communication mesh network. 3-Equipped with GPS to determine the location and ground track heading beside 802.15.4-compliant radios “XBEE Pro Zigbee”for long transmission range.

4. The Challenges 1-When the aircraft glide down, Poses little danger to personnel and property on the ground in the event of an accidental system crash. 2-Path Loss Exponent: for both air-to-air, air-to- ground Wireless links. 3-Antenna orientation: as the transmit antenna gain should depend on the angle between the transmitter antenna and the vector from the transmitting MAV to the receiving MAV.

6. Innovation These “Micro aerial vehicles” can be very small so difficult to be physically captured,equipped with important equipment as tiny camera for video recording or image processing. Deployed behind enemy lines collecting important data from military restricted areas.
