当无线传感网络应用于战场环境时,复杂恶劣的网络环境以及传感节点受限的能源、内存和通信能力导致节点容易失效、遭受攻击或被俘获,从而影响侦察任务的完成。提出一种基于簇的生存性路由协议-SRPC,该协议通过密钥协商和身份认证等机制抵御恶意节点的攻击；并在主簇头被摧毁后启用备用簇头链将监测数据传输到基站。仿真结果表明,SRPC协议可以在均衡能耗的基础上有效抵御恶意节点的攻击,并在簇头节点遭受攻击或者被摧毁后保证数据包的可靠投递,提高了WSN在战场环境中的生存能力。

The sensor nodes easily suffer from failure,attack or capture because of the limited energy,storage,com-munication ability and the complex abominable network environment when WSN is applied to battlefield environment. Thus,the basic scout mission is influenced. A survivability route protocol,SRPC,in cluster-based WSN is put forward. The protocol uses key negotiation and identity authentication mechanism to resist the attacks of malicious nodes. When the main cluster head is destroyed,monitoring data will be transmitted to the base station by the backup cluster head chain. The simulation results show that,SRPC protocol can not only resist the attacks of the enemy malicious nodes based on energy balance,but also assure of reliable delivery of the packets after the cluster head is attacked or destroyed. The survivable ability of WSN in battlefield is improved.
