无线传感器网络中保证覆盖的最少节点部署

无线传感器网络的能量消耗是空间不均匀的,但当前多数的部署方法考虑得较少,网络的能量利用率低,因此提出了保证覆盖率和网络生存期的最少节点部署问题.基于传感器网络的数据传输特性,从提高能量效率和降低剩余能量的角度提出了节点数递减的重叠放置方法和节点密度递减的随机部署方法.两种新部署方法比已有部署方法需要的节点数少,剩余能量低,因而提高了能量利用率.最后,仿真实验表明,两种新部署策略的能量效率是已有方法的3～4倍.     

一种无线传感器网络中的Sybil攻击检测方案

Sybil攻击破坏无线传感器网络中的数据融合、公平资源分配等机制,因此对Sybil攻击的防范与检测具有很重要的意义。将一种基于到达时间差（TDOA）的三维定位引入到Sybil攻击的检测中,算法可以检测存在的Sybil攻击并对Sybil节点进行定位。通过性能分析证明该算法具有开销小、有效性高的特点。

Too little,too late: protecting American soft networks in COIN/CT

ABSTRACT

Assistance of local-national partners is necessary to the USA in order to protect its national security interests throughout the world. These partners, typically individuals who support USA diplomats, service members, and non-governmental organizations (NGOs) in non-combatant roles, form USA soft networks. Due to the nature of their work, many of these individuals associated with the policy and actions of the USA become vulnerable to violent threats from adversaries. In fact, adversaries have grasped that attacking USA soft networks is a logical approach for enemies fighting from positions of weakness. As a result, examination of other domains may yield best practices that build resiliency in USA soft networks, thereby cementing national security interests. Further, agency theory illuminates critical principles in the relationships between local-national partners and field practitioners, and informs policy development efforts as a result.     

Rethinking strategic culture: A computational (social science) discursive-institutionalist approach

ABSTRACT

The strategic culture approach has been suffering from a prolonged theoretical stalemate, despite a surge in case studies, which culminated in the Johnston-Gray debate and subsequent schism. The present paper outlines a new approach designed to overcome this deadlock, and consists of three arguments. First, the three previous generations of strategic culture studies have failed to explain how strategic culture influences behaviour. Second, aligning strategic culture theory-building with discursive institutionalism offers a way to overcome this fundamental fallacy. Third, a research programme for strategic culture should draw on computational social science to enable it to present and test middle-range theories.
