摘　　要：传统的无线传感器网络路由协议中,由于簇首直接传输数据至基站,导致其能量消耗过快并引发过早死亡。因此,本文提出了基于特定数据传输通道的无线传感器网络路由算法:SCDG协议。该协议针对传统的LEACH协议提出了改进措施,簇首只需短距离的将簇内数据信息传送至传送节点,然后通过网络内的特定通道传送至基站,极大降低了簇首的能量消耗。理论分析和模拟实验结果表明,该协议通过均衡节点能耗、缩短数据传送距离,使得网络生命期优于LEACH协议和DEEC协议。In the traditional routing protocols of the WSNs（wireless sensor networks）,as the cluster head directly transfers data to the remote base station,it will result in the excessive energy consumption and its premature death.Therefore,a data gathering protocol for the WSNs based on specific-channels of data transmission is presented in this paper,i.e.the SCDG protocol.The protocol maues improvement in the traditional LEACH protocol.The cluster head needs only transmit data to the transmission node within the short distance,and then forward data to the base station via the specific-channel in WSNs,which greatly reduces the energy consumption of the cluster head.The theoretical analysis and simulation results show that SCDG protocol,through the balanced energy consumption of the nodes and shortened distance of data transmission,makes the network lifetime longer than the LEACH and DEEC protocols.
