建立数学模型，求解能量最优条件下的分群数量(现代通信技术)。同构网络、同构网络、N节点随机部署，网络范围A*A；距离sink较远，认为所有点到sink距离相等。-A mathematical model, solving the energy clustering under optimal conditions the number of (modern communication technology). Homogeneous network, homogeneous network, N nodes are randomly deployed network-wide A* A　far from the sink, that all points equidistant to the sink.
