Panoptes: scalable low-power video sensor networking technologies

Abstract

Video-based sensor networks can provide important visual information in a number of applications including: environmental monitoring, health care, emergency response, and video security. This article describes the Panoptes video-based sensor networking architecture, including its design, implementation, and performance. We describe two video sensor platforms that can deliver high-quality video over 802.11 networks with a power requirement less than 5 watts. In addition, we describe the streaming and prioritization mechanisms that we have designed to allow it to survive long-periods of disconnected operation. Finally, we describe a sample application and bitmapping algorithm that we have implemented to show the usefulness of our platform. Our experiments include an in-depth analysis of the bottlenecks within the system as well as power measurements for the various components of the system.

Power Management in Sensing Subsystem of Wireless Multimedia Sensor Networks

“…The assumption of fixed lenses is based on the current WMSN platforms (Tavli et al, 2011). Almost all of them (SensEye, MicrelEye, CITRIC, Panoptes, Meerkats) (Kulkarni et al, 2005;Kerhat et al, 2007;Chen et al, 2008;Feng et al, 2005;Margi et al, 2006) have fixed lenses and only high powered PTZ cameras have movement capabilities. We consider a monitor area with N wireless multimedia sensors, represented by the set S = {S 1 ,S 2 ,...,S N } randomly deployed.…”

“…To evaluate the scheduling scheme in terms of power conservation, we compare the cooperative scheduled scheme with a single-tier network or a tier of a multi-tier architecture consisting of N nodes monitoring without coordination among them as (Rahimi et al, 2005;Kulkarni et al, 2005;Feng et al, 2005), in which, nodes are awakened with a time period of T. We note that the evaluation is over the sensing subsystem and that the radio subsystem (i.e. ; transmission and reception of packets) is not taken into account.…”

Power aware communication in wireless pervasive smart camera networks

“…Meerkates [3] and Panoptes [4] are early representatives of systems falling into the class of VSNs. They are based on Stargate motes, webcams and PCMCIA WiFi adapters.…”

Voronoi-Based Coverage Optimization for Directional Sensor Networks

“…However, sensors may have a limited angle of sensing range due to special applications, which are denoted as directional sensors. There are many kinds of directional sensors, such as video sensors [4,5], ultrasonic sensors [6] and infrared sensors [2]. The most familiar directional sensors are the video sensors widely used in wireless multimedia sensor networks (WMSNs).…”
