6LoWPAN has been developed to bring IPv6 to even the smallest resource-constrained devices, enabling the vision of an Internet of Things. To be compliant to IPv6's minimum MTU of 1280 Bytes, its fragmentation mechanism allows transmission of datagrams the size of up to 2048 Bytes. Within low power and lossy environments, fragmentation of datagrams can lead to an increase in end-to-end loss rates and to a waste of bandwidth by propagation of fragments of an already lost datagram. We present an extension to an existing analytical, bit-error-based model, which takes into account different route-over forwarding practices in the presence of fragmentation and use it to assess their influence on the end-to-end success rate and the expected number of bits sent. While being not precisely accurate due to the neglect of effects like (self-induced) collisions, the model provides insight into the effects to be expected when using 6LoWPAN's fragmentation mechanism.
