We proposed a time synchronization algorithm based on packet exchange mechanism for wireless sensor networks. A single-hop synchronization scheme was presented where piggyback technique and the least-squares linear regression technique were employed. Multi-hop synchronization scheme consists of topology construction algorithm, single-hop synchronization scheme and time transformation algorithm....

A major challenge in using multi-modal, distributed sensor systems for activity recognition is to maintain a temporal synchronization between individually recorded data streams. A common approach is to use well defined ‘synchronization actions’ performed by the user to generate, easily identifiable pattern events in all recorded data streams. The events are then used to manually align data stre...
