Effect of Paddy Rice vegetation on received signal strength between CC2538 SoC based sensor nodes operating at 2.4 GHz Radio Frequency (RF)

Here we introduce so-far the largest subject-rated database of its kind, namely, "Effect of Paddy Rice vegetation on path-loss between CC2538 SoC 32-bit Arm Cortex-M3 based sensor nodes operating at 2.4 GHz Radio Frequency (RF)". This Database contains the received signal strength  measurements collected through campaigns in the IEEE 802.15.4 standard precision agricultural monitoring infrastructure developed for Paddy Rice crop monitoring from period 01/07/2020 to 03/11/2020. Observations at different node height and vegetation depths in a crop cycle (125 days) with a sampling time of 30 minutes was made in the following two scenarios:

Scenario-1 (Database-1): Nodes of Height=52 cm are deployed and RSS measurement was collected.

Scenario-2 (Database-2): Cluster of nodes with varying height={13,26,39,52,65} are deployed and RSS measurement were collected..
