Investigating the effects of noise on a cell-to-cell communication mechanism for structure regeneration.

In this paper we modified a previous cell-cell communication mechanism of dynamic structure discovery and regeneration to account for the presence of noise that could alter the route of messages transmitted across cells. We report results from a large number of simulation runs where noise was applied to the distance and direction of messages dispatched by cells. Based on our analysis of the results, we proposed an "activation" mechanism where missing cells need to receive a certain number of messages first before they divide and recreate missing cells. We then show that, due to the inherent message redundancy in the organism this mechanism improved the performance of the model even when noise is present on packets.
