Modelling the Spread of Botnet Malware in IoT-Based Wireless Sensor Networks

Table 2

Inputs for the Monte Carlo simulation.

Parameter	Input	Explanation
Message size	Normal dist. sample, mean=50B, sd=5B	Mirai scans less than 250B/sec [2]. Scales with contact rate.
Max power	864000mAs	Typical sensor battery capacity of 240mAh [12]. Converted into mAs.
Power used		To send 1B 1m. Estimated from 30mA peak for node [12].
Contact rates		IoT-based worms should be relatively slower than standard worms.
Recovery rate		Estimated by us based on degree of security engagement.
WSN count		Range of sensor networks available.
Trans. range		Typical range is 10m, we also test larger theoretic range of 100m.
Deployment area		Small and large deployment regions. Will change with application.
