【摘要】 战术互联网是一个高效的、互通的、无缝隙一体化的智能网络,它能够使战场信息得到及时传输和共享,使多兵种、立体化和快速化合作配合作战成为可能。由于战术互联网在现在和未来战场中的重要作用,因此研究对战术互联网的网络对抗策略以获得战场信息的控制权有着积极地作用和意义。论文首先对现有的战术互联网对抗的技术进行了总结,特别是对于战术互联网的网络对抗进行了深入的研究。然后论文从两个方面对战术互联网的网络对抗进行了研究:一方面是以基于TinyOS操作系统的WSN为研究基础,提出了伪sink攻击、丢弃、选择性转发以及篡改等四种不同攻击方法,并进行实现,从而得出这些对抗方法对网络拓扑的影响;另一方面基于端到端时延、丢包率和吞吐量,研究各种攻击方法对网络性能的影响。经仿真验证,随着伪节点个数增加,网络对抗的效果越明显;伪节点的位置越靠近Sink节点或者处于关键链路上,网络对抗的效果越明显。更多还原

【Abstract】 As an efficient, interoperable, seamless integrated intelligent network, the tactical internet is capable of transmitting and sharing the battlefield information timely, which makes it possible to combine the multi-arm, three-dimensional and fast operations. Owning to the important role the tactical internet plays at present and future battlefield, the research of the counterplots of the tactical internet to gain the control of the battlefield information is of great important.The thesis first introduced the existing tactical internet confrontation techniques, especially with a deep research for the network confrontation of the tactical internet. Then the thesis dealt with the network confrontation of the tactical internet from two aspects: on the one hand, on the basis of the study of the WSN based on TinyOS operating system we proposed the four different kinds of counter methods, namely pseudo-sink attacking, discarding, selective forwarding and tampering. The realization of such methods were done as well, from which we reached the impact of the counter methods had on the network topology; on the other hand, we studied the performances of above countermeasures to the tactical internet from end to end delay, packet loss and throughput.The simulations show that with the number of pseudo-nodes increasing, the effect of the network confrontation has is more obvious; the closer the pseudo-node is to the Sink nodes or at the critical links, the results of the network counting is much better.更多还原
