| Outline of Final Research Achievements |
This project developed fundamental technologies for the sustainable sensor networks to mitigate burden to Nature. It included 2 approaches; A) development of power saving protocols for sensor networks with battery driven nodes only to reduce the number of exchanges of nodes, and B) development of data transmission protocols for networks with energy harvesting nodes. For more detail, A1) tradeoff between energy, accuracy and delay was discussed to show the applicability of methods, A2) protocols to disseminate data to several sinks and schemes employing different networks coexisting in the same area to reduce power consumption were proposed, B1) for increasing delivery rate, probabilistic and rateless-coding scatterings were proposed, and B2) basic discussion on wireless power transfer was done.
