Practice application proves that the sink node with multi-communication methods has better practicability.
实际应用证明，多通信方式的汇聚节点具有较高的实用性。
However, the cluster heads close to the sink node lead to energy failure for transmit large amount of data, resulting in "energy hole" phenomenon.
但是，由于靠近汇聚节点的簇头需要转发大量数据，容易导致能量快速衰竭而失效，造成“能量空洞”现象。
In addition, the succeeded masquerader detection algorithm is proposed in this scheme. In this algorithm, the sink node monitors and examines the malicious region.
