Sensor Network with Coordinated QoS:adaptive CPU/memory/network
resource provisioning and scheduling
• Sharp Zaurus SL-5600 with OpenZaurus embedded Linux implementation• Ad hoc network / peer to peer network using WiFi or Bluetooth• Sensor input: video/image using SD camera• Coordinated QoS requires predictive resource allocation and optimization algorithms• Suitable for distributed and collaborative signal and pattern processing tasks

SDA Networks
• Sensor-Decision-Actuator networks– distributed decision-making– sensor-decision-action fusion– greater local autonomy avoids long delay in sending sensor
data to command centre and waiting for commands
• Hierarchical cluster architecture– communication between (inter-) clusters and intra-clusters
• Implements Coordinated QoS

Network central• Devices still have a stand-alone function
– PDA, TV set• In addition, they serve as ‘platform’ for
networked applications– specific device capabilities available on the
network• display, internal hardware (e.g. codecs), internal
memory
– support for hosting (networked) applications• components that can be down- and re-loaded routinely
Apr 22, 2023 19
Fully networked• No stand-alone function
– dedicated, single function components• e.g. networked storage, internet radio
– cheap devices, elementary behavior• sensing, actuating, computing, communicating (sensor
networks)
• Applications arise from cooperation
