Summary

In this chapter, we study the value of information, a more comprehensive instrument than the age of information, for shaping the information flow in a networked control system subject to random processing delay. In addition, we establish a connection between these two instruments by presenting a condition under which the value of information is expressible in terms of the age of information. Nonetheless, we show that this condition is not achievable without a degradation in the performance of the system.
