Design and Implementation of a Video Surveillance System for Linear Wireless Multimedia Sensor Networks

Abstract

Wireless multimedia sensor networks (WMSNs) applications produce large amount of data, which require high transmission rates. An efficient and seamless delivery of multimedia services in WMSN s is still a challenging task. This article presents the design and implementation of a video surveillance system for linear wireless multimedia sensor networks. We adopt a procedure in which every node has unique IP address and can establish a route from itself to sink through multi-hop communication. We present a dynamic queue scheduler which filters the packets according to packet priority. The core component of this system is an open source hardware platform, which is based on Raspberry Pi sensor nodes. Our network is extensively evaluated on 7 Raspberry Pi sensor nodes. We present results of 7 -node real-world deployment in video surveillance application and show that it works well in long-term deployments.
