How and exactly where transport layer comes into picture, especially when a sensor node sends data to other sensor node? (Also can you suggest some resources to study about data transfer in UWSNs)

I have gone through few research papers, but didn't get the clear understanding of role of transport layer while sending data among sensor nodes.

In the context of the OSI model, the transport layer provides end-to-end connection-oriented communication, reliability, flow control, and multiplexing, typically over a multi-hop network.

For UnetStack, the transport service provides a similar functionality, with end-to-end reliability and fragmentation/reassembly for large datagrams, potentially over a multi-hop network. It may also support connection-oriented services for data streaming.
