Ticket-Based Multiple Packet Broadcasting in Delay Tolerant Networks
In Delay Tolerant Networks (DTNs), broadcasting is an important routing function that supports the distribution of data to all users in the network. Efficient broadcasting in DTNs is a challenging problem due to the lack of continuous network connectivity. In this paper, the authors consider the limited bandwidth scenario for DTN broadcasting. Their scheme aims to provide a ticket-based multiple packet broadcasting protocol for a DTN that follows the human mobility patterns - Levy walks and community-based mobility. Their proposed protocol has two steps: packet selection and relay node selection. Packet selection takes place when two nodes come into contact with each other.
