An Adaptive Forwarding Scheme for Message Delivery over Delay Tolerant Networks

In this paper, we propose an adaptive forwarding scheme for achieving efficient message delivery in the mobile sensor delay-tolerant network (DTN). By adaptively adjusting the probability of replicating a message based on the information about the number of existing message copies in the network, the proposed scheme can achieve nice balance between the delivery delay and the average message copy. In addition, by decreasing the number of message copies in the network, the proposed scheme can reduce the network resource consumption in terms of buffer occupation and power consumption.
