The Communication Link Analysis of ZigBee Mesh Networks Using Received Signal Strength Indicator (RSSI) for the Agricultural Slope Environment

Some curves in mountainous areas or slopes can hinder communication in intelligent agriculture. This paper presents the link communication efficiency using the ZigBee protocol. The test scenarios were in an agricultural slope area that blocked communication from the ground to the top of the mountain. Therefore, to strengthen the communication network, we adjust the number of repeaters to expand the network to communicate effectively. The received signal strength indicator (RSSI) and packet success ratio were recorded using the loopback technique with XCTU software. The results showed that the transmitter to the receiver distance of slope-based 75 m, which utilizes signaling repeaters 1, 2, and 3, increased average RSSI values of -83.1, -81.7, and -79.9 dBm, respectively, and the success rate is 100%. In addition, if the system communicates with only the transmitter and receiver, the network is 100% signal loss affected by the curve area in the mountain. However, this experiment shows that ZigBee-based wireless performance data sets are discussed. Furthermore, the result can further implement ZigBee network installation for agricultural slope areas.
