In the composite service which runs for a long time under the heterogeneous and loose-coupled circumstance, the failure of service tends to occur. The transaction and recovery mechanism is urgently needed in order to guarantee the end-to-end QoS of the workflow and satisfy the user requirement. In this paper we address the composite service recovery issue in the way of substitution with the consideration of QoS constraint, based on our previous research work of the transactional construction and processing rules and the global optimization service selection algorithm, TSSA. Firstly, the service execution graph (SEG) is introduced and a service execution solution selection algorithm is proposed to choose one from the solution set of TSSA which has the highest success rate of recovery. Then, the concepts of execution backup path and switch cost are introduced and a search algorithm is presented to search for the optimal backup path when current service failure occurs. Meanwhile, a local induction algorithm based on positive feedback is described which could rapidly construct an transactional execution path when no backup execution path can be found in SEG and also guarantees the transactional constraint of composite service. Finally, experimental results show the recovery algorithm proposed in this paper is efficient and has high reliability. © 2013 IEEE.

With the increasing use of field-programmable gate arrays （FPGAs） in embedded systems and many embedded applications, the failure to protect FPGA-based embedded systems from cloning attacks has brought serious losses to system developers. This paper proposes a novel combinational logic binding technique to specially protect FPGA-based embedded systems from cloning attacks and provides a pay-per-device licensing model for the FPGA market. Security analysis shows that the proposed binding scheme is robust against various types of malicious attacks. Experimental evaluations demonstrate the low overhead of the proposed technique.

Vehicular Edge Computing (VEC) emerges as a promising paradigm by deploying computation and storage resources on edge servers located in close proximity to vehicles, such as roadside units or base stations. This proximity enables VEC to provide abundant resources and low-latency services, catering to the computational needs of vehicles. However, the dynamic nature of traffic flow presents new challenges in terms of task offloading decisions and resource allocation within VEC environments. This paper addresses the task offloading problem in VEC systems, considering the impact of dynamic traffic flow. To address this problem, we formulate an integer programming model that captures the essence of the studied scenario. To devise an efficient solution, we propose a novel traffic flow prediction-based heuristic algorithm (TFPVTO). TFPVTO incorporates different rules and strategies to generate an optimal offloading task sequence, make informed offloading decisions, and allocate resources effectively. To assess the performance of the proposed algorithm, we utilize a real-world traffic flow dataset. In order to fine-tune and optimize the algorithm’s components, we employ a multi-factor analysis of variance (ANOVA) technique. The proposed TFPVTO algorithm is then rigorously compared against other state-of-the-art algorithms, namely TAVF, MONSA, and RANDOM. Through extensive experiments and statistical analysis, we demonstrate the effectiveness and efficiency of the proposed algorithm in terms of task offloading performance. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Microservice workflows are widely used in real-time mobile computing scenarios such as face recognition and speech recognition. The key challenge is to develop efficient, stable, and robust algorithms capable of handling uncertain and fuzzy workflow tasks. In this paper, we consider the real-time microservice workflow fuzzy scheduling problem under VM-Container two-tier resources. A novel model based on triangle fuzzy numbers is formulated. The model encompasses two metrics: cost and degree of satisfaction. In response, this paper proposes an ARIMA prediction-based workflow fuzzy scheduling method (PFSM), comprising five key components: prediction of workflow arrival number, predistribution of task sub-deadlines, ordering of the task pool, task scheduling strategy, and resource management. To assess the performance of the proposed algorithms, several comparison algorithms are selected for analysis, and their performance differences are evaluated using ANOVA. The experimental results demonstrate the significant superiority of the proposed algorithms over the other compared algorithms in terms of overall performance. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

OpenFlow provides a statistics collection scheme for per-flow and aggregate metrics at a user-specified frequency. However, periodic polling for flow statistics cannot well balance the tradeofi between measurement accuracy and limited control channel bandwidth. To further discuss the resource/accuracy tradeofi, this paper extends OpenFlow protocol to add sampling action for each monitoring flow entry, and systematically sample the matching packets to infer the flow-level statistics. Although traffic sampling can somehow be error-prone, it will provide near-real-Time measurements of flow dynamics and determine its accurate polling frequency, which the polling-based approach cannot achieve. In this paper, we propose a per-flow sampling solution to instruct the controller to adaptively adjust polling frequency, then evaluate it in the context of link utilization monitoring. © 2017 Association for Computing Machinery.

We show that an aggregated Interest in Named Data networking (NDN) may fail to retrieve desired data as the Interest sent upstream in advance is recognized as a duplicate one due to its multipath forwarding and dropped by an upstream node. Furthermore, we introduce NDRUDAF, a mechanism based on negative acknowledgement for the router that aggregates the Interests to detect such unanticipated data access failure and assist the requester whose Interest is aggregated fast recovering from the failure. We qualitatively analyze the performance of the NDN with our proposal NDRUDAF and compare its performance with that of the present NDN. NDRUDAF improves the system performance in case of the unanticipated data access failure in terms of data access delay and network resource utilization efficiency at routers. © Copyright 2016 ACM.

In order to minimize the damage caused by key exposure in aggregate signatures, a key-insulated aggregate signature scheme is proposed in this paper. We give the def- inition and the security model of the key-insulated aggregate signature. We also construct a concrete key-insulated aggre- gate signature scheme that meets our definition. Our scheme has the properties of efficient verification and short signature length. We prove the security of our scheme in the random oracle model under the computation Diffie-Hellman assump- tion.

The concentration of dark matter haloes is closely linked to their mass accretion history. We utilize the halo mass accretion histories from large cosmological N-body simulations as inputs for our neural networks, which we train to predict the concentration of individual haloes at a given redshift. The trained model performs effectively in other cosmological simulations, achieving the root mean square error between the actual and predicted concentrations that significantly lower than that of the model by Zhao et al. and Giocoli et al. at any redshift. This model serves as a valuable tool for rapidly predicting halo concentrations at specified redshifts in large cosmological simulations. Copyright © 2025, The Authors. All rights reserved.
