A mobile ad hoc network is an infrastructure less network of mobile devices connected by wireless medium. Such a network has self configuring capabilities. Each device in a mobile ad hoc network is free to move independently in any direction and will therefore, change its links to other devices frequently. Delay Tolerant Networks (DTNs) are the network where the continuous network connectivity is lacking. R-CAR algorithm addresses the issue of routing in such networks. But the paper fails to address issues regarding newly arrived node in a network, prioritization of low hop count carrier node and sharing and dynamic updating of local reputation tables. This paper gives an improved version (IRCAR) that efficiently solves these issues.
