星间网络安全路由选择算法研究

星间网络由于拓扑结构高动态变化、可靠性安全性要求高、节点处理能力有限等特点,使其有别于普通的地面互联网。文章通过分析星间网络特性,对其中安全路由选择的关键技术进行深入研究,提出了一种基于节点信誉度评价与负载感知机制的星间网络安全路由选择算法。该算法采用混合路由配置策略,根据网络实时情况对路由进行动态调整,加入节点信誉度评价策略,减小恶意节点对网络的影响,并且增加节点负载感知机制,根据当前节点负载情况调整路由。最后,文章通过仿真实验验证算法性能,验证了算法在数据包传输成功率方面的优势。

Research on Space Network Secure Routing Algorithm

Because of highly dynamic topology, intense requirement for robustness and security, and limited node resource characters in space network, it is different from ground Internet. This paper analyses these characteristics, studies the key technologies of space network secure rou- ting, and then proposes a space network secure routing algorithm based on node reputation evalu- ation strategy and load-adaptive. The algorithm adopts mixed routing strategy and combines stat- ic routing configure technique and dynamic routing adjustment technique. It uses node reputation evaluation strategy, which can reduce the impact of baleful node to space network, and adds node load-adaptive mechanism, which can adjust routing according on nodes load condition. Finally, data packets transmission success rate is evaluated by simulations.
