The node localization technology is a foundation for practical application in wireless sensor networks. According to DV-HOP positioning algorithm in wireless sensor network low precision, the defect of inaccurate positioning, this paper presents an optimization algorithm of improved DV-HOP based on genetic algorithm. The algorithm is to redefine the scope of initial population, the reference weight, redesigned the fitness function and selection of anchor nodes. The simulation results show that compared with the traditional DV - HOP algorithm, the algorithm without any increase in the node hardware overhead on the basis of significantly higher positioning accuracy.
节点定位技术是无线传感器网络实际应用的基础。针对无线传感器网络中DV-HOP定位算法精度低、定位不准确的缺陷,提出了一种基于遗传算法的改进DV-HOP优化算法。该算法重新定义了初始种群的范围、参考权重,重新设计了适应度函数和锚节点的选择。仿真结果表明,与传统的DV - HOP算法相比,该算法在不增加节点硬件开销的基础上显著提高了定位精度。

Welfare Implications of Deviation from Network Neutrality: A Price Discrimination Application 偏离网络中立性的福利含义:一个价格歧视的应用

This paper investigates how incentives of network operators to deviate from neutrality may create social costs or benefits in different market structures. The deviation from network neutrality is a general form of discrimination based on charging different prices for non-affiliated content and application providers. In this paper, deviation from network neutrality is formulated as a form of vertical foreclosure. While constructing the model two-sided nature of the internet service, the providing market is considered. The author found that, although monopoly network operators have no incentive to deviate from neutrality, the duopoly network operators have this incentive. Welfare analysis suggests destructive results for almost all participants, hence the total surplus in both market structures. In addition, the analysis for the degree of integration between the network operators and their affiliated content and application providers, suggest some policy proposals to discourage their degree of integration.
本文研究了在不同的市场结构下,网络运营商偏离中立性的动机如何产生社会成本或效益。偏离网络中立性是一种基于对非附属内容和应用程序提供商收取不同价格的一般形式的歧视。在本文中,偏离网络中立性被制定为一种形式的垂直止赎。在构建互联网服务的双边性质模型时,考虑了提供市场。作者发现,虽然垄断网络运营商没有偏离中立的激励,但双寡头网络运营商却有这种激励。福利分析表明,对几乎所有参与者都是破坏性的结果,因此两种市场结构都存在总盈余。此外,本文还对网络运营商与其附属内容和应用提供商之间的整合程度进行了分析,提出了抑制其整合程度的政策建议。
