| Research Abstract |
We tried to built the theoretical frame work of sensor networks based on the multi-terminal information theory. In the distributed type sensor networks we found some parts of the region indicating fundamental theoretical limit of communication in the case of Gaussian information sources. In the cascade type sensor networks we study the relay communication networks to obtain an explicit form of the region indication the trade off between the data transmission rate and the security of communication. As an application, we study multicast communication systems which are a combination of distributed sensor networks and serial sensor networks. We established an implementation of this communication networks using overlay networks. In the constructed overlay multicast networks we demonstrated that the coding methods that attain fundamental theoretical limit have also achieve good performance of communication.
