针对现有及经典自适应分簇路由协议 LEACH 存在网络生存周期短和节点可靠性低的问题，提出一种安全的低能耗分簇路由协议S-LEACH。采用多角度信任模型，即从节点数据、通信带宽和剩余能量3个方面对待检测网络内各节点进行信任度评估，建立信任值集合并对照节点信任度阈值进行簇头安全选举，用萤火虫算法模拟实现成员节点聚簇，以单跳或多跳方式与基站节点通信的方法降低由于通信距离较远而带来的额外能耗。实验结果表明，与LEACH协议相比，S-LEACH协议可延长4倍以上的网络生存周期，且与以数据信任度为评测标准的BTSR协议相比，S-LEACH协议可将网络内非信任节点检测率提高2.3%。

This paper presents a safe and low energy consumption clustering routing protocol S-LEACH to solve existing and classical adaptive routing protocol LEACH in the network survival period and the deficiency of the security. It evaluates each node of the detected environment based on trust model from three aspects of node data, communication bandwidth and residual energy. It sets up the node credibility collection to select the head according to threshold value, and uses the firefly algorithm to simulator clustering. The base station node communicates with multiple hops routing algorithms to reduce the additional energy consumption. Experimental results show that S-LEACH’s life cycle in the network prolongs more than four times compared with LEACH and is increased by 2.3%compared with BTSR protocol in the untrusted node detection.
