Sensor tasks assignment is a important problem in sensor management.In order to improve the effectiveness of sensor tasks assignment

a new real-time dynamic assignment algorithm is presented based on the principles of most urgent first to pick a task

earliest completed first to select a sensor

least versatile first to select a sensor and at last select randomly to resolve ties among sensors.Simulation results show that the algorithm is very prompt and effective

it can guarantee the task with the highest priority be executed earliest

also can detect the failure of a task to meet a deadline

furthermore

can improve dynamic load balance among all sensors.
