Controlling access overload and signaling congestion in M2M networks

Abstract

Access overload and signaling congestion are serious issues in machine-to-machine (M2M) networks. These issues can be caused by (i) external events triggering a large number of M2M devices to connect or disconnect all at once, (ii) recurring application events that are synchronized to the exact time (e.g., hour), and (iii) malfunctioning of M2M application or server. It is vital to control access overload and signaling congestion in order to prevent the network from a complete collapse. This paper investigates a few mechanisms to prevent this issue.
