中文说明：我们提出了SEP，异构感知协议的第一个节点的死亡之前延长的时间间隔（我们称为稳定期），这是用于许多应用，其中来自传感器网络的反馈必须是可靠的关键。 SEP基于每个节点的加权选概率根据剩余能量中的每个节点，成为簇头
English Description：
We propose SEP, a heterogeneous-aware protocol to prolong the time interval before the death of the first node (we refer to as stability period), which is crucial for many applications where the feedback from the sensor network must be reliable. SEP is based on weighted election probabilities of each node to become cluster head according to the remaining energy in each node
