### Title: Rate Adaptation and Latency in Heterogeneous IoT Networks

This paper studies the effect of rate adaptation in time slotted Internet of
things (IoT) networks. For a given time slot duration and packets size, rate
adaptation necessitates packet fragmentation to fit the time slot duration.
Accounting for the quality and time resolution of the underlying traffic, this
paper characterizes the tradeoff between transmission rate and packet latency
in IoT networks. Using tools from stochastic geometry and queueing theory, a
novel mathematical framework is developed for static and dynamic rate
adaptation schemes. The results show that there is an optimal static rate that
minimizes latency, which depends on the network parameters. Furthermore, the
dynamic rate is shown to be resilient to different variations in the network
parameters without sacrificing packet latency.
