We consider a spatial system of devices (smartphones and Internet-of-Things devices) on a random street system in R2 equipped with a realistic transmission mechanism respecting interference and delays. The devices form an ad-hoc communication system where smartphones move independently according to the random waypoint model on the streets. We study two separate models (A) propagation of malware and efficiency of countermeasures, and (B) throughput of messages, if sparse infrastructure is added. Our main interest lies on the influence of mobility on the propagation, respectively on the throughput.
Realization of randomly placed devices on a street system of Poisson-Voronoi tessellation type. Upper row: The Markovian SIG-model (Susceptible-Infected-Goodware) stopped at the time the malware has reached the radius u=2.5km (left) and u=5km (right), indicated in black. Lower row: The non-Markovian SIG-model with uniform waiting times on [40sec,120sec] for both infected and immune devices, stopped at the time the malware has reached the radius u=2.5km (left) and u=5km (right), indicated in black.
