Outline of Final Research Achievements

We developed a new communication protocol in combination with MAC and Routing protocols for sensor networks that enables us to maintain sensor networks with practical cost such as replacing batteries of a partial sensor nodes periodically. Our protocol dynamically and adaptively changes the collecting path of sensor data being aware of residual power of nodes to prolong the lifetime of sensor networks. Also, we designed a software that help administrators of sensor networks by collecting required data items periodically from the sensor networks and visualize it. The software enables us to watch networks and to find out the main causes of incidents in case of abnormal events.
