摘要
传感器网络中节点有限的资源以及采用无线的方式转发数据使得在传感器网络内的安全性目标很难实现。基于已有的安全措施,结合低功耗的多路径构造方法,提出了一种具有双重安全性的路由算法。算法借助已有的安全加密措施及密钥分发策略,提供一定的安全性,并且在当上述措施无效时,利用多路径的方式仍然能够再提供一定的安全保证。理论分析和模拟实验表明,算法具有一定强度的抗攻击性和较好的安全性。
It is very difficult to get the security in sensor networks because of the limited resources of nodes and the wireless communication between nodes. A double security-based routing algorithms was proposed based on the existed security arrangement and low power consumption multipath.The existed security arrangement can provide security to some certain case and multipath can provide more security even when security arrangement failed. Theoretic analysis and simulation results show that the new algorithm has better performances.
