中文摘要：
文章基于低功耗自适应分层（LEACH）协议的思想,为了节约簇头节点能量消耗,提出了一种基于能量和密度分簇路由协议CRBED（Clustering Routing Protocol Based on Energy and Density）。在CRBED协议中,簇头选取以簇头节点的剩余能量、节点密度、簇头节点到SINK节点的距离以及簇头节点到簇内节点的距离为依据,并对簇头节点之间的距离和簇形成的规模限定了范围。实验结果表明：与LEACH协议和CHS-AEC协议相比,CRBED协议节约了簇头能量并且减少了整个网络的能量消耗。
英文摘要：
In order to save the energy, this paper proposed clustering routing protocol （CRBED） protocol based on energy and density, which is based on the main idea of LEACH protocol. In CRBED protocol,the cluster head node is selected according to following factors ： the residual energy of node, the density of the nodes,the distance between cluster head node and sink node and the distance between cluster head node and cluster node. And the distance between cluster head nodes and the scale of the cluster is in a fix range in this protocol. The experiment results show that compared with LEACH, the CRBED can save the energy of cluster and reduce energy consuming of the whole network.
