Edge Computing and Sensor-Cloud: Overview, Solutions, and Directions

Sensor-cloud originates from extensive recent applications of wireless sensor networks and cloud computing. To draw a roadmap of the current research activities of the sensor-cloud community, we first investigate the state-of-the-art sensor-cloud literature reviews published since the late 2010s and discovered that these surveys have primarily studied the sensor-cloud in specific aspects, security-enabled solutions, efficient management mechanisms, and architectural challenges. While the existing surveys have reviewed the sensor-cloud from various perspectives, they are inadequate for the three key issues that require urgent attention in the sensor-cloud: reliability, energy, and heterogeneity. To fill this gap, we perform a thorough survey by examining the origins of the sensor-cloud and providing an in-depth and comprehensive discussion of these three key challenges. We summarize initial designs of the new edge-based schemes to address these challenges and identify several open issues and promising future research directions.

Automated summary

Sensor-cloud, originating from wireless sensor networks and cloud computing, has been extensively studied in specific aspects such as security, management mechanisms, and architectural challenges. However, existing research lacks in addressing the urgent issues of reliability, energy, and heterogeneity in the sensor-cloud. To bridge this gap, this study conducts a thorough survey, providing an in-depth discussion on the origins and comprehensive analysis of these three key challenges.
