TL;DR: A new energy‐efficient multilevel heterogeneous routing (EEMHR) protocol for WSNs is proposed and results show that by varying the initial energy and node heterogeneity parameters, the network lifetime of EEMHR is improved by 17% in comparison with SEP and MCR.
Abstract: Wireless Sensor Networks WSNs are being used in wide areas of applications for data collection and processing. Energy management is one of the crucial issues that need special attention in WSNs. But most of the existing solutions for energy management are restricted in defining the number of levels for node heterogeneity for efficient energy management. Due to this restriction, a performance degradation has been observed in most of the applications in WSNs. Hence, keeping in the view of the aforementioned issue, in this paper, we proposed a new energy-efficient multilevel heterogeneous routing EEMHR protocol for WSNs. Nodes are divided in to k levels of hierarchy in the proposed solution. A variable threshold defined by the ratio of number of alive nodes for current round to the total number of nodes is proposed for the selection of cluster heads. The performance of the proposed approach is evaluated by varying the various parameters of the network in comparison with other state-of-the-art protocols such as stable election protocol SEP and multihop communication routing MCR. Simulation results show that by varying the initial energy and node heterogeneity parameters, the network lifetime of EEMHR is improved by 17% in comparison with SEP and MCR. Moreover, EEMHR provides better stability and distribution of cluster heads in comparison with SEP and MCR. Copyright © 2014 John Wiley & Sons, Ltd.

TL;DR: The proposed LMI based PID control reduces the required control effort while assuring that pre-defined design conditions for dynamic response of system like settling time, overshoot and Integral square error are met.
Abstract: In this paper an approach for designing an optimum gain of Proportional integral derivative (PID) controller subject to Linear matrix inequality (LMI) constraints for load frequency regulation of single area and multi-area power system is presented. The LMI based PID control reduces the required control effort while assuring that pre-defined design conditions for dynamic response of system like settling time, overshoot and Integral square error. Further a subset of complex plane with respect to the design conditions is mapped onto a stability region in the coefficient space of the characteristic polynomial. Next, the stability region in the polynomial coefficient space defines LMI as a constraint, which is used to find the optimum gain of PID controllers. A series of simulations results are performed for efficacy of proposed design approach especially for dynamic response of single area and multi-area power system which is superior in comparison to other design method obtained from literature. The simulation results demonstrate that the designed controller can effectively restrain the impact of variation in system parameters and load disturbance.

TL;DR: A detailed security proof shows that the proposed protocol is provably secure under a random oracle model based on the difficulty of the ring learning with errors problem, and the informal security analysis and experimental implementation show that the protocol is practical for real-world mobile client–server environments.
Abstract: The rapid advances of wireless communication technologies along with the popularity of mobile devices are enabling users to access various web services anywhere and anytime. Due to the openness of wireless communications, security becomes a vital issue. To provide secure communication, many anonymous authentication protocols in mobile client–server environments based on classical mathematical hard assumptions (i.e., discrete logarithm problem or integer factorization problem) have been presented in last two decades. However, both of the two assumptions can be solved by postquantum computers in polynomial time, which means these protocols are never secure in the postquantum era. To mitigate such types of attacks, we propose an ideal lattice-based anonymous authentication protocol for mobile client–server environments. A detailed security proof shows that our proposed protocol is provably secure under a random oracle model based on the difficulty of the ring learning with errors problem. Furthermore, the informal security analysis and experimental implementation show that our proposed protocol is practical for real-world mobile client–server environments.
