主　　题：wireless sensor networks reliability servicedifferentiated location-based routing mechanism 

摘      要：Designing reliability differentiated services for missions with different reliability requirements has become a hot topic in wireless sensor *** with a location-based routing mechanism,a quantified model without full network topology is proposed to evaluate *** introducing a virtual reference point,the data transfer is limited in a specified *** reliability function of the area is given.A detailed analysis shows that the function increases quadratically with the distance between the source node and the reference node.A reliability differentiated service mechanism is then *** simulation results show the efficiency of the proposed mechanism.
