Empirical approach of ad hoc path loss propagation model in realistic forest environments

摘要

An Internet of Things (IoT) application that employs wireless transmission data such as Wireless Sensor Node need to be designed well enough, So its data doesn't loss in its transmission between the node. Therefore to build an IoT application such as Wireless Sensor Node path loss propagation model is a must. In this paper, we proposed a new path loss model to be used on a near ground 2.4 GHz Wireless Sensor Node network in forest environment application. Our methods are using one of IoT node such as Microcontroller Wemos to do walk test and then capture statistical data the RSSI level every 5 meters and compare it to the simulation. Our new proposed model has a better result for forest environment at about 2.01 dB forest with High grass more than 30cm, 0.69 dB low grasses less than 10cm, and 0.26 dB without grass compare with other model and compare to the measurement at 65 meters.
