Title: Selecting redundant nodes when addressing availability in wireless visual sensor networks
Issue Date: 2014
Abstract: As Wireless Sensor Networks have been employedto support critical monitoring applications, network availabilityhas become a major design concern. In these networks, redundancy can be exploited to enhance the attainable availability level,where redundant sensors can replace faulty nodes. When cameraenabled sensors are deployed to retrieve visual information, theperception of redundancy changes considerably, since the redundancy of visual sensors depends on the monitoring requirementsof the applications. In such context, characteristics as deploymentdensity, viewing angle and sensing range are relevant whenplanning wireless sensor network applications, directly impactingin the number of redundant nodes. We propose an algorithmto select redundant nodes in Wireless Visual Sensor Networks,according to the application requirements. Moreover, we discusshow parameters of the deployed network can influence on thenumber of redundant nodes.
