One of the key design issues in ad hoc networks is the development of rollback recovery model for providing fault-tolerance in MANET. Because the potential problem of MANET is limited energy, probability of fault occurrences is more. Hence, check pointing is done at trusted nodes when faults are encountered, for successful rollback to the last saved state. This paper makes trust a vital factor to be determined. The proposed algorithm aims to reduce the rollback recovery time by retrieving the checkpoint data through trusted nodes.
