TMHF: Transmit Max Hop First forwarding Strategy to Optimize the Performance of Epidemic Routing Protocol

Delay Tolerant Networks vary from conventional networks in that they have reserve constraints, unbalanced mixture traffic, data redundancy, network dynamics, and energy balance. Moreover due to node mobility DTN suffers from unpredictable connectivity and limited transmission duration. A mobile node in DTN routing may not be able to transmit all messages from its forwarding queue; therefore the order in which messages are transmitted becomes very important. In this paper, we propose forwarding queuing mechanisms named Transmit Max Hop Count first (TMHF) in which when the connection opportunity arises, the node will transmit the message with max hop count.
