Intermittently connected mobile network (ICMN) is a delay-tolerant ad hoc network that is made up of mobile nodes. In real time scenarios like battlefield, wildlife tracking sensors nodes usually suffer from frequent network partitions. In these scenarios, there is no end to end path exists between source and destination due to frequent link breaks and high mobility of nodes. To address these challenges in these networks, several flooding schemes have been introduced but the resource consumption is high. Then many spraying methods also introduced. But the existing spraying methods will not spread the message faster to reduce the average delay. Hence, we propose a new spraying technique in which spraying is done by combining density aware spray and wait with multi-hop periodic spraying. So, there is a chance of spreading the messages faster. Hence, the delay will be decreased and delivery ratio will be increased while maintaining the limited number of replicas of message.
