Peer to peer propagation in vegetation media for wireless sensor networks

The extension of wireless communication systems and their application in rural environments, require radio propagation models adapted to this situations: presence of vegetation (both trees and shrubs), low transmitted powers, or peer to peer configurations. This work presents the results of a large radio propagation measurement campaign, conducted in different vegetation environment, with low antenna heights, and tuned to frequencies assigned to wireless networks: 2.4, 3.5 and 5.8 GHz bands.
