Abstract :
Delay tolerant Networks (DTNs) is an approach to network architecture which will targets the heterogeneous network. Delay tolerant network may will deals with mobile nodes even the mobile nodes don’t have any end-to-end connection. From the above context, contacts between the two nodes are limited because of its low density of active network nodes. So make sure routing statics to permit the time delivery from source to destination with maximum probability. If the portability between nodes can’t known before which may cost of repeat the actual information, this process may consume lots of power and storage resources. In this paper we explain about packet pair property in First-In-First-Out queuing networks and shown you how it can measure through bottleneck link bandwidth.
The First-In-First-Out queuing network judges the difference in two packet landing times with equal sizes from same source to destination. We have described the protocols for optimality of proper delivery and mean delay. Here we may differentiate the two conditions, one is source may overwrite its packets in relay nodes and second is source may not.
