Wireless sensor networks are expected to become an important social infrastructure which helps our life to be safe, secure, and comfortable. In this paper, we propose design methodology of a network architecture for fast and reliable transmission of urgent information in wireless sensor networks. In the methodology, several simple and fully-distributed control mechanisms which function in different spatial and temporal levels are introduced to each node to offer differentiated transmission to packets in accordance with their importance. We also show an example of a network architecture designed following the methodology. Our practical experiments showed that the architecture successfully improved the delivery ratio and delay of the urgent sensor information.
