Abstract:

A task assignment method was proposed to address the task assignment issue of camera networks in the intelligent traffic systems. The workload of camera node and the tasks quality of service are both taken into consideration with the introduction of fields of task. A task transfer approach has been put forward on the basis of the relative value between the adjacent camera nodes to ensure tasks quality of service. The proposed method has been implemented in the embedded smart camera networks system. The experiment result demonstrate that the method could improve both the system average resource utilization of about 50% and the success ratio of the task assignment is about 40% when compared to conventional method.

Key words: task assignment, camera networks, task transfer, intelligent traffic
