Abstract: In WSN, routing protocols play an important role in network performance. This paper mainly deals with quality of service which consists of two parameters namely low delay and data integrity. These parameters are difficult to achieve simultaneously but using IDDR these can be achieved simultaneously. By constructing a virtual hybrid potential field, IDDR separates packets of applications with different QoS requirements according to the weight assigned to each packet, and routes them towards the sink through different paths to improve the data fidelity for integrity-sensitive applications as well as reduce the end-to-end delay for delay-sensitive ones. Using the Lyapunov drift technique, we prove that IDDR is stable. Simulation results demonstrate that IDDR provides data integrity and delay differentiated services.
