Fighting infection Suppose nodes face a constant probability p of being infected (e.g., malfunctioning, taken over) in every time epoch. A mobile agent can visit 1% of the nodes in each epoch and fix/replace them if they are infected. It is further desired that less than 1% of the data produced by nodes be corrupted. Determine the maximum tolerable infection probability if

(a) nodes simply report their own data and (b)

three nearby nodes with identical access to the data perform a majority vote.
