Cloudlet-based cyber foraging framework for distributed video surveillance provisioning

Abstract

Continuous monitoring activities in surveillance system generate massive amount of data to be transferred from Internet-of-Things (IoT) devices (i.e., cameras and sensors) to a centralized processing unit for analysis. However, several issues need to be addressed, including data migration over bandwidth limited and high latency communication networks, and the heterogeneous nature of data obtained from the surveillance system. The aim of this paper is to develop a scalable and lightweight intelligent distributed surveillance system that make use of an integrated framework of Internet-of-Things (IoT) and cloud computing. It leverages on the pervasiveness in IoT and ubiquitous property of cloud computing technology. This paper introduces the concept of bringing cloud closer to the IoT in order to address the resource poverty of IoT and the dependency for massive data transmission to distant cloud. For providing real-time on-site object detection, this paper instantiates a cloudlet on resource-rich nearby infrastructure which is connected to the IoT devices for distributed retrieval and processing of critical and sensitive data.
