Wireless Connectivity of a Ground-and-Air Sensor Network
This paper shows that, when considering outdoor scenarios and wireless
communications using the IEEE 802.11 protocol with dipole antennas, the ground
reflection is a significant propagation mechanism. This way, the Two-Ray model
for this environment allows predicting, with some accuracy, the received signal
power. This study is relevant for the application in the communication between
overflying Unmanned Aerial Vehicles (UAVs) and ground sensors. In the proposed
Wireless Sensor Network (WSN) scenario, the UAVs must receive information from
the environment, which is collected by sensors positioned on the ground, and
need to maintain connectivity between them and the base station, in order to
maintain the quality of service, while moving through the environment.Comment: 8 pages, 11 figure
