Typically, wireless senor network (WSN) is widely used in the various fields for several applications. It is a promising technology due to its higher range of the network connectivity and the fast set up of the network. But there will also be a presence of the some of the eradicating issues which will decrease the network growth. In the WSNfield the prediction of link failure is regarded as the baffling one till now. The proposed technique offers a detailed idea on the failure of link. The proficient trusted Node ID dependent resource reservation protocol (PTN-RRP) is presented in this approach. In this, the shortest path is then recognized with the use of approach weighted based end-to-end delay. This technique identifies the shortest path from a specific preliminary position to the target and thus could enhance the detectionrate. By means of recognizing shortest path, the hop address and sequence numeral is being incorporated to the protocol. Once afterwards the shortest pathdetection, the failure of link is estimated. A link failure structure in the trusted etiquetteemployed has the developedcapabilityto predict and fix issues related to link failure. After that, to identify the attack cause intended for the failureof link, a method of posterior probability evaluation is carried out to find the kind of attack. Finally, the proposed method performance isassessedover simulation study. The simulation outcomeauthorizes that the projectedmethod is effective highly in the link breakage detectionand the implemented algorithm for shortest path recognition in this will decreases the detecting shortest path time period. The performance outcome is compared with existing techniques to prove the effectiveness of proposed methodology.
