A hierarchical indexing strategy for optimizing Apache Spark with HDFS to efficiently query big geospatial raster data

open access: yesInternational Journal of Digital Earth, 2020
Earth observations and model simulations are generating big multidimensional array-based raster data. However, it is difficult to efficiently query these big raster data due to the inconsistency among the geospatial raster data model, distributed ...

Evaluating model and simulation analyzing for P2P Churn

open access: yesTongxin xuebao, 2007
Most P2P algorithms based on distributed Hash table(DHT) faced Churn,which was caused by the continuous process of node joining and failure.A Churn evaluating model was proposed and its formulized description,which could give some important instructions ...

A Distributed Learned Hash Table

open access: yes2025 IEEE 33rd International Conference on Network Protocols (ICNP)
Distributed Hash Tables (DHTs) are pivotal in numerous high-impact key-value applications built on distributed networked systems, offering a decentralized architecture that avoids single points of failure and improves data availability. Despite their widespread utility, DHTs face substantial challenges in handling range queries, which are crucial for ...

PyCAN: Open-source Python software of N-dimensional Content-Addressable Network

open access: yesSoftwareX
We propose PyCAN, the first open-source Python implementation of N-dimensional Content-Addressable Network (CAN) with full feature sets to maintain peer-to-peer structure. Existing CAN implementations supports limited functions of Distributed Hash Table (

Smart Chaining: Templing and Temple Search

open access: yesIEEE Access
Hash tables continue to be at the forefront of applications that require fast data lookup, but their usefulness in practice depends on effective collision resolution. Classical approaches like chaining (linked lists) and open addressing (linear/quadratic/

A Scalable Architecture for Secured Access to Distributed Services

open access: yesEAI Endorsed Transactions on Scalable Information Systems, 2017
Web services which are an implementation of Services Oriented Architecture (SOA), are emergent technologies and promising the development, the deployment and the integration of Internet applications. They are initially based on three main layers that are

Security-Enhanced Decentralized Content Sharing in Publish/Subscribe System

open access: yesIEEE Access
We consider a content dissemination model, where the contents disseminated from a content source on a regular or event-driven basis are shared among the group members, without directly contacting the content source.

Survey on Distributed Hash Tables

open access: yes, 2006
In this paper we review distributed hash tables (DHTs) that work as overlay networks on top of the IP network. We compare these DHTs under a number of key aspects that concern performance, scalability and self-configurability. Additionally, since these networks are not suitable for wireless ad hoc networks, we shortly review techniques that can be used
