ABSTRACT:
In a Delay Tolerant Network (DTN), routing protocols are developed to manage the disconnected mobile
nodes. We propose a routing protocol named HALF (Handoff-based And Limited Flooding) in DTN that
can work in both infra-structured and infra-structure less networking environment and hence it can
improve the performance of the network significantly. In this paper, it is shown that HALF gives
satisfactory delivery ratio and latency under almost all conditions and different network scenarios when
compared to the other existing DTN routing protocols. As the traffic intensity of the network grows from
low (.2) to high (.75) values, HALF shows about 5% decrease in the delivery ratio compare to much
larger values showed by the other routing protocols and on the average takes same time to deliver all the
messages to their destinations. As the radio range is increased over the range from 10m Bluetooth range
to 250m WLAN range, due to the increased connectivity, the delivery ratio and the latency are increased
by 4 times and decreased by 5 times respectively.
