In the view of the DV-Hop positioning algorithm which relies on the distance vector and beacon nodes, several aspects are improved: the average hop distance and hop count are corrected;a method to detect the abnormal distribution of beacon nodes is used to avoid the influence of the abnormal distribution on the positioning performance. The proposed algorithm is simple and effective. Simulation results show that compared with the traditional DV-Hop algorithm, the performance of the proposed algorithm is greatly *** performance is even even superior to that of the algorithm mentioned in literature [10]

We present a scheme for the practical decoy-state quantum key distribution with heralded single-photon source. In this scheme, only two-intensity decoy states are employed. However, its performance can approach the asymptotic case of using infinite decoy states. We compare it with the standard three-intensity decoy-state method, and through numerical simulations, we demonstrate its significant improvement over the three-intensity method in both the final key rate and the secure transmission distance. Furthermore, when taking statistical fluctuations into account, a very high key generation rate can still be obtained even at a long transmission distance.

After wormhole attacks the routing mechanism of wireless sensor network (WSN) is damaged, then the hop count and distance between nodes cannot be well matched, so that the WSN becomes the anisotropic sensor network, resulting in security treats for WSN. Considering that wormhole attacks can cause the changing of node connectivity, through the theoretical analysis and derivation, the paper has proposed a method which detects wormhole attacks with the connected relation of high connectivity nodes, and optimizes routing with the help of the normal nodes outside the wormhole. Simulation results show that the algorithm can well detect wormhole attacks and has better localization accuracy In addition, the effect is more obvious in the case of the wormhole nodes with large communication radius and long distance.

3D-MPSoCs integrate cores of several vendors and support different applications on a single die, providing large performance and cost reduction. 3D-technology presents many security challenges and offers new opportunities to implement protection countermeasures. 3D-NoCs can be explored to assist the overall security of the system. In this work, we propose a 3D-NoC hardware architecture able to protect the 3D-MPSoCs against software attacks. Dynamic firewalls create elastic security zones by wrapping a set of components according to a trust policy, guaranteeing the protection and efficient execution of all applications. We compare our approach with several 3D-protection proposals and we show that our mechanism performs a fast detection of attacks, decreases the cost of security in terms of power and provides a high level of security.

The present random access (RA) scheme in terrestrial LTE (T-LTE) cannot be applied in LTE-satellite system, for the remarkable miss detection probability caused by large difference of propagation delay in satellite communication system. In this paper, a Peak to Average Ratio after Deleting Quasi-users (PAR-DQ) detection algorithm is proposed. The algorithm can deal with the large difference of propagation delay in satellite system. Quasi users are selected based on constraint coefficients which are defined according to difference of propagation delay first. And then, the average of correlation values is calculated after deleting quasi users. Finally, the peak to average ratio is chosen as decision variable in this algorithm. The threshold setting scheme is also presented which can be adjusted according to the required false alarm rate in multi-user scenario. Simulation results manifest that the proposed algorithm can achieve excellent performance in satellite environment.

This paper describes the improvement of a transcutaneous core temperature thermometer by modifying the configuration, in terms of height and radius, of the thermometer using the so-called dual-heat-flux (DHF) method. The motivation of these modifications is to decrease the volume of the thermometer so as to reduce the transverse heat flow inside, in other words, to preserve the underlying assumption of the DHF method that heat flows from the inner part of human body through skin onto the thermometer longitudinally. The modification's effect is evaluated by both numeric modeling based on finite element method and experiment. The results of simulations and experiments show that a lower-in-height and larger-in-radius configuration will improve the accuracy of the thermometer. Prototypes of 22.0 mm radius can attain satisfactory accuracy with error less than 0.5°C when heights are 8.0 mm or less. Copyright © 2014 SCITEPRESS - science and technology Publications.

Weaknesses derived from Through-Silicon-Vias (TSV)-based physical configurations of three-dimension Multiprocessor System-on-Chip (3D-MPSoC) can be exploited by malicious software to attack the system. By means of vertical communication manipulation an attacker is able to modify, spy and even denial the TSV communication. In this paper we propose 3D-LeukoNoC, a flexible and efficient security architecture based on 3D-NoC communication structure which, as the biological immune system, is able to detect attacks, isolate sensitive vertical communication while guaranteeing the correct system behavior. We compare our approach with several 3D-protection proposals, including the simple extension of 2D security countermeasures. We show that our solution outperforms other approaches with respect to attack detection while decreasing cost and performance impact on the system.
