Trust Based Node Recovery and Checkpointing Techniques in Manets

Abstract

Checkpointing is a process of determining the vulnerability of node in case of any attack occurs in the network. It depends on the cluster change count value of the node. If the measure of the hop exchanges required to reach the destination node from the current node, is above the previously specified value, the node under consideration is unsafe and safe points must be implemented in between the path and different subnetworks within that network must have their own implemented safe points. The message must commits to the safe points as it reaches the respective sub networks. The message in the networks evolve over the certain subnetworks. The each subnetwork has the checkpoint node, that serves the purpose for communication between different subnetworks, or between the hops in different subnetworks. This phenomenon supports the system efficiency and preserves the robustness. The process retrieval methods, therefore, should be implemented with the use of the safe points to prevent system degradation. In this research paper, an efficient recovery protocol is designed for distributed transactions in MANETs so that failures can be minimised. Dynamic analysis has also been done and it is compared with other existing protocols to validate the attained result.
