Abstract EN
In delay tolerant network (DTN), an end-to-end path is not guaranteed and packets are delivered from a source node to a destination node via store-carry-forward based routing.
In DTN, a source node or an intermediate node stores packets in buffer and carries them while it moves around.
These packets are forwarded to other nodes based on predefined criteria and finally are delivered to a destination node via multiple hops.
In this paper, we improve the dissemination speed of PRoPHET (probability routing protocol using history of encounters and transitivity) protocol by employing epidemic protocol for disseminating message m , if forwarding counter and hop counter values are smaller than or equal to the threshold values.
The performance of the proposed protocol was analyzed from the aspect of delivery probability, average delay, and overhead ratio.
Numerical results show that the proposed protocol can improve the delivery probability, average delay, and overhead ratio of PRoPHET protocol by appropriately selecting the threshold forwarding counter and threshold hop counter values.
