A secure destination-sequenced distance-vector routing protocol for ad hoc networks

Journal of Networks 2010年第8期5卷 942-948页

This paper presents a secure destination- sequenced distance-vector (SDSDV) routing protocol for mobile ad hoc wireless networks. The proposed protocol is based on the regular DSDV protocol. Within SDSDV, each node maintains two one-way hash chains about each node in the network. Two additional fields, which we call AL (alteration) field and AC (accumulation) field, are added to each entry of the update packets to carry the hash values. With proper use of the elements of the hash chains, the sequence number and the metric values on a route can be protected from being arbitrarily tampered. In comparison with the secure efficient ad hoc distance vector (SEAD) protocol previously proposed in the literature provides only a non-decreasing protection on the metrics, SDSDV can provide complete protection. © 2010 Academy Publisher.

Due to the development of internet rapidly, the secure transmission of information has become more and more importance. Until now, there are many scholars study in the topic of data hiding. Specially, the reversible data hiding scheme catch the researcher's attention. No matter how the researchers use the different technology to embed the secret information, they always try to increase the hide space within the permission quality of the cover image. However, the hiding positions are subject to the highest point by using the NSAS-scheme or HKC-scheme. To overcome this shortcoming, a reversible data hiding based on adaptive hiding location will be proposed in this paper. According to the experimental results, we can prove that our proposed scheme still not only keeps high embedding capacity and stego-image quality but also maintain the better security. © 2010 IEEE.

In this paper, we will propose the T-S fuzzy controller design for a class of networked control system (NCS) with the network transmission delay and the data packet dropout. In the NCS, the controlled plant is approximated to the Takagi-Sugeno fuzzy model (T-S fuzzy model). Then, we propose the fuzzy controller design based on the T-S fuzzy model, to inhibit the effect of the network transmission delay and the data packet dropout, and to guarantee the stability of the overall system. Next, we analyze the stability and the robustness of the overall system by the Lyapunov-Krasovskii function and the Lyapunov stability theorem, and obtain the Lyapunov stability criterion. After that, the Lyapunov stability criterion would be presented in the linear matrix inequality format to solve the control problem more efficiently by using the Schur complements. Finally, the computer simulations are given to demonstrate the validity and the performance of the proposed control strategy. © 2012 IEEE.

Jamming attacks can severely affect the performance of wireless networks due to the broadcast nature. The most reliable solution to reduce the impact of such attacks is to detect and localize the jammer. In this paper, we propose our research into participatory sensing based scheme, named as CrowdLoc, for the collection of measurements to collaboratively localize a jammer in wireless ubiquitous environments which are suffering from jamming attacks. CrowdLoc mainly contains three phases: 1) Crowds as Sensor. The sensor nodes at the boundary of jammer region are weakly impacted by the jamming attack, and conduct the sensing functions to record the information related to the jammer, such as received signal strength (RSS);2) Crowds as Network. These boundary nodes cooperate with each other to share the recorded measurements of the jammer;and 3) Crowds as Estimator. Based on the crowdsourcing measurements of the jammer, we propose a novel localization scheme to estimate the position of the jammer: Range-based Jammer Localization (RJL). As opposed to existing solutions, RJL is independent of the propagation parameters, which are difficult to obtain in hostile jamming circumstance. The experimental results indicate that the localization accuracy of RJL is close to the Cramer-Rao Bound (CRB) for the RSS-based Localization in most area. © 2011 ACM.

A computer vision system that employs an RGBD camera network to track multiple humans is presented. The acquired views are used to volumetrically and photometrically reconstruct and track the humans robustly and in real time. Given the frequent and accurate monitoring of humans in space and time, their locations and walk-through trajectory can be robustly tracked in real-time. Copyright 2014 ACM.

In a very less time from its advent, blockchain technology has entered into mainstream research all over the world. The Bitcoin cryptocurrency is the first open-source implementation of blockchain technology. The application of blockchain technology is not restricted to financial services only;several other sectors especially healthcare is increasingly focusing their attention to grab potential and unique features of blockchain technology like immutability, security, and trust. This paper aims to review the exploration of blockchain technology in the healthcare domain in recent years and study how these emerging technologies help healthcare to speed up treatment procedures and mitigate the effects of the COVID-19 pandemic. © 2021 IEEE.

Blockchain technology is one of the emerging technologies of the decade. Immutability, reliability, and distributed ledger are the main features of the blockchain, making this technology very popular in the short time from its advent. The use of blockchain technology is not only restricted to the financial sector, but the healthcare sector is also focusing its attention on a blockchain. Immunization Programs can be assisted by blockchain technology to achieve reliability, security, and traceability. In this paper, we describe the blockchain-based reliable approach for the Immunization Program using the Hyperledger Fabric platform to provide a practical solution to the challenges of the current system. The system will maintain a real-time view of the vaccination record and provide a single integrated view of localized and diverse records. This united form of the data help the doctors for better diagnosis in case of disease, and specialists to make better strategic plans for Immunization. © 2022 IEEE.

In order to overcome problems of DENCLUE and improve it for medical image segmentation, we propose HD-DENCLUE algorithm. It takes the optimization step length to find density attractor, designs a hill-down strategy to give different density thresholds for different clusters and stops at hill-down data i.e. the edge data of this cluster. Experiments show that HD-DENCLUE can decrease time overhead, have better clustering effects than DENCLUE and get the edges of each cluster. Copyright 2007 ACM.

Tourist: Self-adaptive structured overlay

Tourist: Self-adaptive structured overlay

Structured overlays provide a basic substrate for many peer-to-peer systems. Existing structured overlays can be classified into two categories, 0(logN)-hop ones and 0(1)-hop ones. The former are suitable for large and dynamic systems, while the latter are suitable for small or stable ones. However, for the lack of adaptivity, it is difficult for a peer-topeer system designer to choose from these two kinds of overlays because the eventual size and churn rate are not easy to predict in the design phase. To address this problem, we propose a self-adaptive structured overlay Tourist, which can adapt itself to the changing environment dynamically. Tourist nodes determine their routing table size autonomously: nodes with different capacities hold routing tables with different sizes. This makes Tourist sufficiently utilize all the nodes ' allowable bandwidth to achieve as high routing efficiency as possible. Tourist also allows each node to adjust its routing table size dynamically, which is the essential reason for the self-adaptivity. Simulation results show that in a common 1,000,000-node system, Tourist can route all the messages within two hops and each node only pays no more than 1% bandwidth for its routing table maintenance. © 2007 IEEE.

Sociodemographic bias in language models (LMs) has the potential for harm when deployed in real-world settings. This paper presents a comprehensive survey of the past decade of research on sociodemographic bias in LMs, organized into a typology that facilitates examining the different aims: types of bias, quantifying bias, and debiasing techniques. We track the evolution of the latter two questions, then identify current trends and their limitations, as well as emerging techniques. To guide future research towards more effective and reliable solutions, and to help authors situate their work within this broad landscape, we conclude with a checklist of open questions. ©2024 Association for Computational Linguistics.
