Abstract
Disclosed is a system and method for intelligent traffic control using wireless sensor and actuator networks. The system comprises a control center, M regional gateways, and N sensor and actuator nodes. The N sensor and actuator nodes and L cluster heads form L clusters. Each cluster includes a cluster head and at least a sensor and actuator node. The control center, the M regional gateways, and the N sensor and actuator nodes form a multi-layer structure. Each N sensor and actuator node may real-time detect traffic states, and exchange information with other nodes via a wireless communication having a self-recovery function. The system and method applies a distributed computing strategy to automatically adjust the traffic control on each traffic flow, thereby achieving an efficient traffic control.
