Security and Privacy in Fog Computing: Challenges

TL;DR: This paper provides an overview of existing security and privacy concerns, particularly for the fog computing, and highlights ongoing research effort, open challenges, and research trends in privacy and security issues for fog computing.
Journal ArticleDOI

A Performance-to-Cost Analysis of IEEE 802.15.4 MAC With 802.15.4e MAC Modes

TL;DR: A performance-to-cost analysis of Deterministic and Synchronous Multi-channel Extension (DSME) and Time-slotted Channel Hopping (TSCH) MAC modes of IEEE 802.15.4 MAC protocol is carried out to analyze the trade-off of choosing a particular MAC mode over others and present the applicability of different MAC modes to different application scenarios.
Journal ArticleDOI

Beacon Synchronization and Duty-Cycling in IEEE 802.15.4 Cluster-Tree Networks: A Review

TL;DR: This paper analyzes various works carried out to address beacon synchronization and duty-cycling issue in IEEE 802.15.4 networks and establishes a co-relation between these two mechanisms and shows how the former effects the later and vice-versa.
Journal ArticleDOI

A Survey on the Noncooperative Environment in Smart Nodes-Based Ad Hoc Networks: Motivations and Solutions

TL;DR: In this article, the authors survey the main roots for motivating nodes to adapt selfish behavior and the solutions for handling such nodes in wireless ad hoc networks, including trust-, punishment-, and stimulation-based mechanisms.
Journal ArticleDOI

NCHR: A Nonthreshold-Based Cluster-Head Rotation Scheme for IEEE 802.15.4 Cluster-Tree Networks

TL;DR: The proposed nonthreshold CH rotation scheme (NCHR) supports topological changes, node heterogeneity, and can also handle CH failures, and is shown that the proposed scheme boosts network lifetime, incurs less rotation overhead, and needs fewer CH rotations compared to other related schemes.
