Effect of Paddy vegetation on path-loss between CC2650 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 CC2650 SoC 32-bit Arm Cortex-M3 based sensor nodes operating at 2.4 GHz Radio Frequency (RF)".

This proposal examines the received signal strength through measurement campaigns in the IEEE 802.15.4 standard precision agricultural monitoring infrastructure developed for Paddy Rice crop monitoring from period 13/07/2019 to 18/11/2019.

Observations at different node height and vegetation depths in a crop cycle (128 days) with a sampling time of 30 minutes were made in the following two scenarios:

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

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