Correctness of the Chord Protocol

Internet of Things (IoT) can be seen as a cooperation of the various heterogeneous devices with limited performances, that participate in the same system. By they nature, these devices can be very distributed. The core of every IoT system is its discovery and control service. The Chord protocol is one of the first, simplest and most popular distributed protocol and can be use as a backbone of the discovery and control services of an IoT system. In this paper we prove the correctness of the Chord protocol using the logic of time and knowledge. We consider Chord actions that maintain ring topology with the additional assumption the nodes are not allowed to fail or leave.
