Delay Tolerant Networking (DTN) is a network utilized to send and receive data using different protocols. It has the high potential to set up the simulation settings for infinite IoT, cloud, edge, and fog applications. Generally, it allows interoperation in the inter-device distance which is from the very short-range to the very long-range communication. Our PhD guidance in delay tolerant networks service is focused on the architectures, deployments, and recent advantages in DTN.
This page deals with the important functions and innovative research topics in DTN. Let us first start with the dynamic uses of DTN.
What is the use of DTN?
DTN helps to find the technical problems in heterogeneous networks and this process leads to the deficit in the flow of network connectivity and it is an approach to the network architecture. Now, let us discuss the notable working principles of DTN.
What is the use of DTN delay tolerant networks?
DTN helps to store and forward the message switches by covering a different layer protocol and that is called bundle layer. The bundle in DTN is known as the middle layer of the application and transport layer. It consists of bundle header, control information, and the application data unit which provide services such as,
- Custody Transfer Announcement
- Forwarding Bundle Announcement
This page paid more attention to the recent research ideas in the DTN field. So, the PhD research scholars who are attentive in the DTN field can make use of this spot to know and discuss more important updates about DTN. Now, let us have a glance over the novel research topics in DTN.

Thus, our research experts in DTN provide the appropriate results for any kind of research topic in DTN. Now, let us discuss in what way we compute delay in DTN.
How to compute routing delay in DTN?
- Propagation Time
- The definite time used to transmit the message from the source to the destination over the wireless channel is called propagation time.
- Send Time
- Complete-time required to prepare the packet at the application layer and send it to the network layer is called send time. The send time includes delays introduced by the operating system.
- Transmission and Reception Time
- Certain time is used for transmitting or receiving a message at the physical layer. It includes the delay time and it depends upon the size of the packet and the rate of the wireless channel.
- Access Time
- While the channel access process in MAC layer delay is introduced. According to the application-specific protocol it is highly variable and one of the main components in synchronization.
Here, we have enlisted some delay factors with the value and the nature of that delay factor.
- Byte Alignment
- Value – 0-400ms
- Nature – Deterministic and it can be calculated
- Encoding / Decoding
- Value – 100-200ms
- Nature – Deterministic and depends upon radio chipset
- Interrupt Handling
- Value – <5ms (in most cases)
- Nature – Depends on interrupts and non-deterministic
- Value – <1ms (up to 300 meters)
- Nature – Depends on distance and non-deterministic
- Transmission / Reception
- Value – 10-20 ms
- Nature – Depends on packet size and non-deterministic
- Value – 10-500 ms
- Nature – Depends on channel contention and non-deterministic
- Send / Receive
- Value – 0-100 ms
- Nature – Depends on processor capacity and non-deterministic
