Fault-tolerance is one of the major issues in ad hoc networks. Failure probability is greater because of limited energy level of mobile nodes and dynamic topology constraints. Whenever a node is dubious to be attacked, checkpointing of data is done on some reliable and trustworthy node. So, evaluation of trust factor of a node is an important aspect that largely influences the recovery process. This...
In this work, we propose a trust based secure checkpointing and recovery technique in Mobile Adhoc Network (MANET). In resource constrained MANET, ensuring secure checkpointing using cryptography increases overhead and consumption of resources. Hence additional overhead of secure checkpointing should be minimized. Here proposed trust model is combined with the technique of encryption for secure checkpointing...
