New research opportunities are emerging as Wireless Sensor Networks (WSNs) are penetrating into the industrial domain; one such prospect is within time synchronization. For the operation of WSNs, partial or full time synchronization is needed. Time synchronization is very important in a distributed WSN for the purpose of data fusion, time interval calculation, context-free access to radio channel, coordination, event ordering and power management. This paper proposes a novel distributed time synchronization protocol for WSNs, which compensates for the non-deterministic delays by estimating the uncertainties in the synchronization packet delays.
