无线多跳网络安全路由算法
|
摘要
针对窃听者相互合作下的无线多跳网络,提出一种考虑物理层安全的路由算法.该算法在假定未知窃听者位置及其信道状态信息(CSI)的前提下,得到系统端到端安全连接概率(EESCP)表达式,通过最大化网络EESCP,得到一种使用传统Bellman-Ford算法即可实现的最短路径路由算法,并在此基础上进一步提出一种改进的Bellman-Ford算法.仿真结果表明,所提出的算法不仅适应于不同规模的网络,而且相较于传统算法能够极大地提高网络的安全性能.
This paper proposes a physical-security-based routing algorithm for a wireless multi-hop network in the presence of multiple colluding eavesdroppers. The algorithm firstly obtains end-to-end secure connection probability(EESCP) without the knowledge of the locations of the eavesdroppers as well as the channel state information(CSI). Then,a shortest-path routing algorithm, which can be simply realized using traditional Bellman-Ford method, is introduced by solving the EESCP maximization problem. Furthermore, an improved Bellman-Ford algorithm is designed to get higher security level. The simulation results demonstrate that the proposed algorithm can be applied to a network of arbitrary size, and has significantly higher security performance compared with the traditional ones.
