I've read such papers. They tend not to discuss the initial SYN/ACK handshake
and the timer related to that (probably because their simulation tools default
to not simulating SYN/ACK), or consider the implications of TCP slow start with
long propagation delays.

the sensor networks I'm familiar with use IP, but don't use TCP, for
many of the same underlying reasons.
