Each application have different Qos (quality of service) in same platform on wireless sensor network. We are proposing coldspots technique and multi path relay algorithm using coldspots technique. It improve the data fidelity and end to end delay of the sensitive to overcome problems like delay minimization and high data integrity and data fidelity. By applying a virtual hybrid potential field IDDR separates packets based on their weight.And the packets are forwarded to the destination through different path applications.Data fidelity can be improve by collecting idle buffer space or under loaded paths to cache excessive packets.For prioritizing packets transmission we are using lyapunov drift technique. IDDR also provide good energy efficiency and scalability.
