The lack of survivability in typical wireless sensor network （WSN） synchronization protocols leads to innova- tion in this hot topic

the diffusion-based time synchronization protocol （DTSP） makes nodes maintain themselves onto a global time consensus via local exchanges of timestamp information. DTSP cancels the synchronization root existing in most protocols which may cause security problems

by utilizing time-division and fault-tolerance technology

the surviv- ability is enhanced further. Appling DTSP with typical WSN nodes

experiments give excellent results in survivability

precision and scalability.
