Abstract
A Delay Tolerant Network (DTN) is characterised as partitioned networks with absence of end to- end connectivity and therefore conventional routing techniques applicable to MANET cannot be applied. DTN have found to be useful in number of application areas where prioritization of messages is essential. We have worked with prioritization of messages considering minimum consumption of network resources such as Buffer size and TTL. Two routing algorithms, Prophet and DSG are used for the implementation of the algorithm. The results show that highest priority messages are delivered more when the buffer and TTL is minimum as compared to low priority messages.
