无线自组织网络的联合安全路由选择和功率优化算法

针对无线自组织网络在窃听环境中的安全传输问题，该文提出了一种无线多跳自组织网络的联合安全路由和功率优化算法。首先，在窃听者服从泊松簇过程(PCP)这一假设下推导得到了系统安全中断概率(SOP)和连接中断概率(COP)的表达式；然后以安全中断概率约束下的连接中断概率最小为准则，针对给定路径推导得到了源与各跳中继的最优传输功率，并进一步获得了源与目的节点间的最优路由。仿真结果表明，该文所提系统安全中断概率和连接中断概率的表达式与蒙特卡洛仿真结果相符，所提算法可获得与穷举搜索方法接近的安全性能，显著优于传统方法。

Joint Secure Routing and Power Optimization Algorithm for Wireless Ad Hoc Networks

A joint security routing and power optimization algorithm for wireless multi-hop Ad hoc network is proposed in an eavesdropping environment. Firstly, the Secrecy Outage Probability (SOP) and expressions of Connection Outage Probability (COP) are derived under the assumption that the distribution of the eavesdroppers follows the Poisson Cluster Process (PCP). Then, in view of minimizing COP with the constraint of SOP, the optimal transmission power of each hop is derived for any given path. Based on that, the optimal route from the source to the destination is obtained. The simulations on COP and SOP show that the derived theoretical results agree well with the Monte-Carlo simulations. It is also shown that the security performance of the proposed algorithm is close to that of exhaustive searching, and also outperforms the traditional method.
