Data fusion application is one of the most popular applications in Wireless sensor networks (WSNs). Time synchronization is an important technology for data fusion applications due to its necessary for data fusion in the networks. Aimed at reliable time synchronization performance, this paper proposes a novel two-way time synchronization protocol (NTSP). Combing node’s clock model and two-way packet exchange mechanism, NTSP makes time synchronization protocol more precise and much steadier. NTSP adopts simulated annealing (SA) algorithm to defend random noise and malicious delay attacks. Network simulations are carried out to analyze performances of NTSP on time synchronization accuracy, convergent rate and defensive degree for malicious delay attacks. Comparing to traditional time synchronization protocols, NTSP is an effective time synchronization protocol in WSNs.
