The Profile-based Data Processing Method Using Wireless Sensor-actuator Networks

摘要

Wireless sensor and actuator networks (WSANs) bring many gains to smart building systems. When a control system is unified by a WSAN, and particularly if the network size is wide, a distributed communication and a control method are necessary. But, multi-hop communication and packet sizes among sensors and actuators cause challenges in making such systems. This paper proposes and evaluates a new profile based data processing scheme for a smart building system with WSANs. Experimental results show that the proposed' method effectively achieves the reduction of packet numbers and sizes with self-controlled sensors and actuators. We also discuss how to dynamically extend the service of a WSAN with only profile distributions and updates.
