As the nodes are self resourced in ad hoc networks, the denial of service as relay hop by any node is frequent. This is due to resource levels of that node are lower than the threshold, in another act the node may be irrational and selfish. In such cases the irrational or selfish nodes leads to attacks such as black-hole and grey-hole and also causes the poor routing performance under metrics such as throughput, Packet Delivery Ratio and Packet Delivery Fraction. In this paper, we device a node laurel verification and update strategy to avoid irrational and selfish nodes from network activities. The laurel verification is done in between periodic intervals and laurel update incorporates at routing completion state. We conducted experiments using simulations build by NS-2, which are promising and optimistic over models stated in recent literature.
