In this paper, an adaptive fuzzy control algorithm based on genetic algorithm is proposed. The membership function of fuzzy controller and the optimization of fuzzy rules are carried out simultaneously.

Efficient Ring Signature Scheme Without Random Oracle from Lattices

Among post-quantum alternatives, latticebased cryptography is the most promising one, due to its simple operations, reduction from aver-age-case to worstcase hardness, and supporting of rich functionalities. Ring signature enables a user to sign anonymously on behalf of an adaptively chosen group, and has multiple applications in anonymous e-voting, anonymous authentication, whistle blowing etc. However, most lattice-based ring signature schemes were constructed in the random oracle model from lattice basis delegation and they suffer large verification key sizes as a common disadvantage. This work proposes an efficient ring signature scheme from lattice basis delegation without random oracle based on the extended split-SIS problem, whose security is approximately as hard as the worst-case SIVP problem. Our scheme is proved to be anonymous and existentially unforgeable under latticebased assumptions. Finally, the verification key size is significantly reduced to a small constant, instead of increasing linearly with the number of ring members.

Complex network services can be constructed by composing simpler service components in a well defined way. To benefit most from such an approach, service components should be reusable for different services. Furthermore the composition must be performed automatically and customized to the service execution platform. In this paper, we focus on node local aspects of service *** contribute design and implementation details of Chameleon, a system targeted at automatic service composition. Our system is based on (1) service descriptors containing meta-information about service components and (2) a service creation engine composing and installing services in a platform specific and automatic way. Target platforms are modeled as active nodes featuring Execution Environments (EEs) to serve as runtime environments for service components. To validate our concepts, we implemented an active node. It features two different EEs, an EE based on Click router technology, which is suitable for forwarding plane services, as well as a general purpose Java-based EE. A demonstration service, which performs traffic shaping, is briefly presented to illustrate the concepts and their applicability. © IFIP International Federation for Information Processing 2004.

Joint optimization of source and relay precoding in non-regenerative MIMO relay systems

We investigate the problem of precoding optimization in an amplify-and-forward multiple-input-multiple-output relay system. Most reported works on this problem focus chiefly on the design of relay precoder without simultaneously optimizing the direct link. In this paper, we propose a method for joint source/relay precoder design, taking both direct and relay links into account. Our design is based on maximizing the mutual information (MI) under limited transmission power constraints at the source and relay, respectively. We first formulate a constrained optimization problem before relaxing the original cost function for tractability and derive a MI lower bound. This elaborate bound can asymptotically approach the exact expression of MI in an iterative fashion. In contrast to previous strategies, we then prove that the optimal structure of the source and relay precoders jointly convert the multiple-input-multiple-output relay channel into a bank of single-input-single- output relay channels without having to assume a beamforming structure to simplify the derivation. Specifically, the linear precoding design problem degenerates into power loading among multiple single-input-single-output relay channels. Applying standard Lagrange technique results in a scalar convex optimization, and it can be readily solved by iterative water filling. Numerical examples demonstrate that the proposed scheme, either exploiting partial or full channel state information, significantly outperforms the existing methods.

3D Geometry-Based UAV-MIMO Channel Modeling and Simulation

A more general narrowband regular-shaped geometry-based statistical model(RS-GBSM) combined with the line of sight(LoS) and single bounce(SB) rays for unmanned aerial vehicle(UAV) multiple-input multiple-output(MIMO) channel is proposed in this paper. The channel characteristics, including space-time correlation function(STCF), Doppler power spectral density(DPSD), level crossing rate(LCR) and average fade duration(AFD), are derived based on the single sphere reference model for a non-isotropic environment. The corresponding sum-of-sinusoids(SoS) simulation models including both the deterministic model and statistical model with finite scatterers are also proposed for practicable implementation. The simulation results illustrate that the simulation models well reproduce the channel characteristics of the single sphere reference model with sufficient simulation scatterers. And the statistical model has a better approximation of the reference model in comparison with the deterministic one when the simulation trials of the stochastic model are sufficient. The effects of the parameters such as flight height, moving direction and Rice factor on the characteristics are also studied.

Area avoidance routing in distance-vector networks

Area avoidance routing in distance-vector networks

Network routing may be required, under certain applications, to avoid certain areas (or nodes). These areas can be of potential security threat, possess poor quality or have other undesired characteristics. Thus, protocols that can perform area avoidance routing can be beneficial for many objectives. Such routing is particularly challenging in distance-vector networks, where only the shortest-distance information is available to the nodes. We address this challenge by algorithms that retrieve distance-vector information from other nodes in the network, referred to as reference nodes, and exploit it for computing guaranteed area-avoiding paths. Having these paths, the source can direct the packets using loose source routing towards the destination. We lay out the model for area avoidance routing and study several algorithms for calculating area-avoiding paths. In addition, we address the problem of dynamically selecting reference nodes. We show, through analysis and extensive simulation, that in many cases a small number of reference nodes are sufficient for area avoidance routing1. © 2008 IEEE.

On the design and application of Thermal Isolation Servers

On the design and application of Thermal Isolation Servers

Recently, there has been an increasing trend towards executing real-time applications on multi-core platforms. However, this complicates the design problem, as applications running on different cores can interfere due to shared resources and mediums. In this paper, we focus on thermal interference, where a given task (τ1) heats the processor, resulting in reduced service (due to Dynamic Thermal Management (DTM)) to another task (τ2). In real-time domain, where tasks have deadline constraints, thermal interference is a substantial problem as it directly impacts the Worst Case Execution Time (WCET) of the effected application (τ2). The problem exacerbates as we move to mixed-criticality systems, where the criticality of τ2 may be greater than the criticality of τ1, complicating the certification process. In this paper, we propose a server based strategy (Thermal Isolation Server (TI Server)) which can be used to avoid thermal interference of applications. We also present a heuristic to design TI Servers to meet the timing constraints of all tasks and the thermal constraints of the system. TI Servers are time/space composable, and can be applied to a variety of task models. We also evaluate TI Servers on a hardware test-bed for validation purposes. © 2017 ACM.
