- Abstract
Time synchronisation is required for a variety of distributed control applications in wireless sensor networks (WSNs). In this study, a consensus‐based time synchronisation protocol is presented. The proposed protocol considers asynchronous framework where the sensor nodes can have different time‐periods, starting times and input update times. The communication links are assumed to be unreliable. The clocks in a WSN are modelled by a time‐varying system with time‐delay terms. The objective is to design local control inputs to achieve time synchronisation by processing the information received from available neighbour nodes. By employing tools from non‐negative matrix and graph theories, the convergence analysis is presented. Numerical examples are given to demonstrate the effectiveness of the proposed protocol.
