Resource Management Policies for Wireless and Visual Sensor Networks Wendi Heinzelman

In this book, we explore application-aware techniques for managing the limited resources in wireless sensor networks, focusing on ways to maximize the network lifetime for clustered wireless sensor networks and for visual sensor networks. First, we explore energy efficient clustered network architectures, as well as cluster head selection policies that satisfy the application-specific QoS constraints. Next, as we believe that the real potential of wireless sensor networks lies in their integration with advanced sensing modalities, we explore the use of application-aware resource allocation specifically for visual sensor networks. Designing efficient visual sensor networks is challenging due to their high demand for network resources, their tight QoS requirements and the unique sensing capabilities of the imagers. We focus specifically on camera-node management policies, discussing methods for the selection and scheduling of camera-nodes in user-centric visual sensor networks. These management strategies provide an efficient means of managing the network's resources by reducing the redundant data while providing the user with the required quality of data.
