| Research Abstract |
We have developed a ZigBee sensor network for ecology observation of seabirds, Streaked Shearwaters, listed in IUCN Red List. From the observed results of experiment at Awashima island, we have obtained the ecologically useful information. It has been confirmed by data that the increase of sea temperature affects the pattern of leaving or returning to the nest. Furthermore, with the use of RFID, it becomes evident that chicks are often training at night, which has not been proven so far.
Timing synchronization is essential in case where multiple sensor nodes are deployed on the same place. GPS or NTP can not be easily used in some fields. We have explored a new timing synchronization method among nodes in ZigBee network. With this method, a system has been developed to detect and attack harmful birds in rivers. Predation of fishes by harmful birds induces economical deficit as well as ecological damage in rivers. So, the system will also be useful to maintain ecological environment.
