Inspired by some imaginary biological phenomena,this paper experiments the long distance communication in distributed systems by adaptive stochastic attempts. The experiments let tumors emit virtual smells to attract medicine particles. Those virtual smells act as one-way messengers to help roving medicines to locate tumors. On the Movable Feast Machine, communication within event-windows is accurate and bidirectional. Without unique global addresses, these experiments help to extend communication distances outside event-windows, thus to increase the robustness of the Movable Feast Machine.

Basic elements include Cell, Medicine, M-Emitter and M-Consumer. A group of cell atoms forms a big structure to resemble a real Cell. Medicine atoms move randomly. They only have certain possibilities to find tumors and kill them. To increase this curing chances, we designed the Aura element. Tumors will emit Aura atoms which can be attract Medicine atoms. In real world, this Aura can be implemented by magnetic fields or electric fields. Auras have a timer representing their life time. The longer this timer is, the strong the virtual magnetic fields is. The effect of attracting medicine is stronger then. However, too strong auras also damage healthy cells. We will adjust the threshold of the Aura strength to find out its effect on the whole system.
