A Survey: An Energy Efficient Routing Protocol in Delay Tolerant Networks (DTN)

چکیده
In a resource constrained network such as Delay Tolerant Networks (DTN), efficient utilization of resources such as energy is important for optimum network performance. However, due to nodes mobility, frequency of encounters and message transmission, most of node’s energy in this type of network is continuously depleted. A node’s energy in DTN plays an important role in the success of delivering messages. The lower the energy a node has, the lower its chance to deliver messages across the network. Thus, a proper energy-efficient routing protocol should be selected for message transmission for DTN applications. This issue leads us to investigate on the energy consumption of nodes in DTN. This paper presents a survey on energy efficient routing in DTN. Keyword: -Delay Tolerant Networks, Energy Efficiency, Epidemic Routing, n-Epidemic Routing etc....

Due to the increasing use of wireless communications, infrastructure-less networks such as Delay Tolerant Networks (DTNs) should be highly considered. DTN is most suitable where there is an intermittent connection between communicating nodes such as wireless mobile ad hoc network nodes. In general, a message sending node in DTN copies the message and transmits it to nodes which it encounters. A...
