Implementation of RSSI Module in Omnet++ for Investigation of WSN Simulations based on Real Environmental Conditions

The simulation of different scenarios and protocols under environmental conditions is a success key for a reliable Wireless Sensor Network (WSN). For some applications, the variation of the weather conditions as the temperature and humidity could affect the Received Signal Strength Indication (RSSI). Running multisimulation scenarios is required to evaluate the proposed protocols and architectures before their deployment in a real-world network. The more the simulator mimics the real world, the closer the evaluation results to the real network. In this paper, we have integrated temperature and humidity in the Omnet simulator and have taken into account the impact of these environmental factors on the RSSI based on real experiments that were carried out using the CC1101 radio ship of Panstamp Avr2 at 868 MHz frequency.
