A NOVEL APPROACH FOR SIMULATING A BIO-CONTAMINATION PROCESS

Keywords: Simulation, CSMA/CA, bio-contamination, Ad-hoc, WLAN Abstract: The phenomenon of bio-contamination in a population of individuals being contaminated in a near by near physical, viral or bacterial contact could be compared by analogy with a near by near exchange of "atomic" data between mobile entities of an ad hoc network. Would the tools of wireless communication engineering then make it possible to contribute in the modeling of a bio-contamination process? Does the use of CSMA/CA in order to share the “contamination medium” make it possible to simulate this process of contagion? To establish the limits of the analogy, we consider the most unfavorable case, the systematic contamination of proximity. A susceptible mobile becomes contaminated if it passes near a contaminant mobile at a distance lower than the contamination distance. Simulations under NS2 highlight the effect of the overall radiation compared to the power used for emitting the atomic data representing the virus and reveal an optimal frequency of atomic data diffusion in the case of a population with strong geographical density moving in confined environment.
