In this paper, a novel physical layer key generation method for extracting secret key from mutual channel information in orthogonal frequency division multiplexing OFDM systems has been proposed. Firstly, a well-designed data extraction process has been introduced to reduce the redundancy and inconsistency of channel state information CSI. After that, a new quantization method using gray code is proposed. Furthermore, an associated method is designed to reduce key error rate KER. With these improvements, higher key generation rate KGR can be obtained compared to existing methods. Finally, available secret keys have been generated after information reconciliation and privacy amplification. The proposed method has been analyzed and verified in long term evolution advanced LTE-A systems and the generated secret keys have passed randomness test.

Although the application of the exhaustive search ES algorithm in the energy conservation strategy can realize the simultaneous switching off of multiple eNBs in the existing eNB-based Evolved Node B networks, it fails to satisfy the practical requirement of network deployment with the heavy computation burden. On account of this, this paper proposes an optimal switching-off eNB selection OSS algorithm in homogeneous networks. By selecting a certain cell within the coverage of multiple eNBs, the OSS algorithm can make an evaluation of the increment of network load caused by the switching off of various eNBs in the coverage area. Then it can sort one by one all of the eNBs that are to be switched off under the condition that the QoS Quality of service requirement of all of the users has been met. Afterwards, the OSS algorithm will switch the users according to the principle of least network load increment and eventually find an eNB that shows the optimal energy saving effect in sleep mode. The simulation results reveal that the OSS algorithm can satisfy the requirement of efficient energy conservation in wireless networks. Additionally, with low computational complexity, it also will facilitate network deployment.

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.

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.
