摘要：Radio waves Frequency (RF) propagating in vegetation environments usually facing much higher path loss than in environments those without vegetation. Therefore, well known of the propagation path loss through the vegetation area is critical for communication and sensing of Wireless sensor network (WSN) in such environments. Furthermore, the well known of the elevation of the antenna of the sensor nodes is very important for accurate measurement of the path losses in such environment. This paper presents the impact of each part of trees on WSN signal propagation inside the mango tree greenhouse to elect the appropriate elevation of the antennas. The empirical results show that the foliage affects is high and thus communication losses is higher while lowest losses obtained when nodes located within trunk elevation or less. Thus, the optimum antennas elevation must be within trunk level so that the reliable and higher network connectivity can be achieved.
