<p>The paper presents an agent substitution algorithm for a dataflow network implemented on the Smart-M3 platform. Such a substitution allows to transfer control and computational context from an unexpectedly disconnected agent to a programmable substitute agent for the period of absence of the first agent in the network. It also guarantees integrity of the information flow, i.e. the functioning of all dependent services is not disrupted after the agent disconnection. When the agent returns to the network the reverse substitution occurs also with keeping integrity of the information flow. The paper gives a description of the dataflow network implementation and substitution mechanism structure on the Smart-M3 platform. The detailed description of the substitution algorithm including initialization, registration, and bidirectional substitution phases is given. The proposed substitution algorithm was implemented by the authors in the substitution mechanism as a part of the RedSIB semantic information broker on the Smart-M3 platform.</p>
