Two options for describing a random walk when a node is silenced, with the silenced node shown as a ring. In both cases, the sender still communicates module entries through the silenced node. a Using the same code as before: when the random walker visits the silenced node, the sender does not use the corresponding node-visit codeword. b Designing a new code: the silenced node does not receive a codeword and visits to that node cannot be encoded
