军事通信中ad hoc网络路由协议性能分析 总被引:1,自引:0,他引:1
移动ad hoc组网灵活,抗毁性很强,将在未来的军事通信中发挥重要作用。因此,对于移动ad hoc网络研究中的首要的路由问题作了探讨,先简要介绍了两种典型的路由协议OLSR(Optimized Link State Routing)和AODV(Ad hoc On-Demand Distance Vector Routing),接着利用网络仿真工具OPNET分析了AODV的协议特点,最后比较了两种路由协议的性能。仿真结果表明AODV路由开销小,但时延大,节点移动过快时存在路由稳定性的问题;OLSR路由开销很大,但时延相对较小。因此在搭建军用adhoc网时,应根据实际使用情形做出选择。 相似文献

ABSTRACTThe Chinese People’s Liberation Army (PLA) is halfway through a multi-decade modernization process. It has begun a major restructuring effort as it shifts its focus from a traditional continental defensive posture to a more maritime-oriented emphasis. In order to create more balanced joint force, it has adjusted the structure of its highest command organization, the Central Military Commission; abolished the former four General Departments and seven Military Regions; created five new joint Theater Commands and service-level commands for the Army and Rocket Force; and is reducing the size of its active duty force by 300,000 personnel. While seeking to overcome numerous internal obstacles, the PLA continues to develop and improve its capabilities to conduct integrated joint operations to deter a variety of threats to China’s sovereignty and territory and, if deterrence fails, to win informationized local war. 相似文献

The post-civil war agreement phase is vulnerable to credible commitment problems, a lack of government capacity to implement, and/or mutual vulnerability to retribution from violating the agreement. This study’s main contribution is to demonstrate the combined utility of mediation and UN peacekeeping. Mediation builds trust and confidence and works with the parties to design an efficacious agreement conducive to, among other features, tamping down post-agreement violence. Peacekeeping stems violence and facilitates the implementation of the agreement. Agreements that are mediated and followed by UN peacekeeping are expected to be more robust in terms of staving off violence. We report the effects of the mediation–peacekeeping interaction using a method correcting for a common misinterpretation of interaction terms. We test logit and hazard models using a sample of full and partial civil war peace agreements signed between 1975 and 2011. Controlling for agreement design, democracy, and income per capita, the results indicate mediation and its interaction with peacekeeping reduce the probability of renewed/continuing violence and have a positive impact on agreement duration. We also report brief case study evidence from the 1990s peace process in Guatemala. 相似文献

In the mid-2000s, the United States Army was embroiled in counterinsurgency missions in Iraq and Afghanistan that required deeper understanding of local social systems. The Army turned to systems thinking and design thinking to model and understand the world, define problems, and develop approaches to strategic and operational challenges. However, the Army’s approach as expressed in publications and doctrine encourages the development of complicated, unsupported, and unfalsifiable hypotheses. The risk is that the Army will act on incorrect assumptions and develop plans that are fragile. 相似文献

Given the advances made in conventional weapon capabilities, precision should by now be the accepted and expected norm in cyberspace as well. In this article I argue that developing precision cyber weapon systems, to be used during a lawful conflict, can be an important part of a responsible national security strategy to reduce the amount of violence and physical destruction in conflicts. I first describe a precision cyber weapon system in a military context. I then present three compelling rationales for the development of precision cyber weapon systems based on ethical, operational, and financial considerations. To support the position, I address several arguments that have been levied against their development. Thereafter I present several recommendations for a way ahead. 相似文献
