Sensing data relay apparatus and method, sensing data management apparatus and method, a sensor network system thereof are provided to prevent data loss and transmission delay by stably transmitting data in a state that security information and close nodes are not established. A pre-authentication data delay unit(211) relays first sensing data received from a mobile sensor node(200) to a base node(220) at minimum transmission rate, and a security information receiving unit(212) receives and stores not only share encryption key about the mobile sensor node but also re-setup data transmission rate from the base node. An authentication unit(213) authenticates second sensing data received from the mobile sensor node with the share encryption key, and a post-authentication data relay unit(214) relays the authenticated second sensing data to the base node at the re-setup data transmission rate.
