Domain based routing algorithm for DTN (The single copy case)
In order to improve delivery ratio and reduce average delay and network cost in Delay and disruption Tolerant Network (DTN), This paper puts forward a domain based single copy routing algorithm (DBR) for BirdNet, which is a special DTN based on mobile sensor nodes installed on birds with GPS function enabled. In this algorithm, the GPS position information from the bird is used, to assign the mobile node to domains, to calculate delivery predictability, so that the invalid and duplicate data transmission will be less. By preceding measures, this algorithm can reduce the transmission delay as well as improve delivery ratio. Furthermore, the way of assign nodes to domain significantly reduces the routing protocol packets between nodes, which decreases the energy consumption, and extends the lifetime of nodes.
