Time synchronization of Wireless Sensor Network (WSN) nodes is essential in those applications requiring distributed task scheduling or data aggregation and fusion. In this paper, a new synchronization procedure based on a distributed Proportional Integral (PI) consensus controller is described. Compared to other similar solutions, the proposed approach keeps into account the effect of random communication...
Time synchronization of wireless sensor network (WSN) nodes is essential to schedule orderly communication and monitoring tasks. In this paper, a synchronization algorithm based on linear control theory is used to compensate at run-time both time offsets and clock frequency skews. The proposed approach is innovative for two reasons. First of all, the controller correcting the local timers is able...
