We have analyzed fundamental properties of sensor network on the basis of the multi-terminal information theory. In particular, we have considered the mixed sources and mixed channels, and derived the fundamental limits on the reliable communication. This is because some situations in which we know the class of probabilistic model but we do not know its parameter, can be formulated by the mixed models. We have determined the optimal second-order achievable rates in the single source coding problem and the optimal achievable rate region in the multi-terminal source coding problem. Moreover, we have observed that the optimal achievable rates in some problems on channel coding can be determined by using the similar approach.

在多终端信息论的基础上，分析了传感器网络的基本性质。特别地，我们考虑了混合信源和混合信道，给出了可靠通信的基本极限。这是因为在某些已知概率模型类但不知道其参数的情况下，可以用混合模型来表示。我们确定了单端信源编码问题的最优二阶可达速率和多终端信源编码问题的最优可达速率区域。此外，我们还观察到，在信道编码的某些问题中，可以使用类似的方法来确定最优可达速率。
