Query: Average power limitations in Sliding Window Contention Resolution
  Diversity Slotted Aloha   Recently a new Random Access technique based on Aloha and using Interference
Cancellation (IC) named Sliding Window Contention Resolution Diversity Slotted
Aloha (SW-CRDSA) has been introduced. Differently from classic CRDSA that
operates grouping slots in frames, this technique operates in an unframed
manner yielding to better throughput results and smaller average packet delay
with respect to frame-based CRDSA. However as classic CRDSA also SW-CRDSA
relies on multiple transmission of the same packet. While this can be
acceptable in systems where the only limit resides in the peak transmission
power, it could represent a problem when constraints on the average power (e.g.
at the transponder of a satellite system) are present. In this paper, a
comparison in terms of normalized efficiency is carried out between Slotted
Aloha and the two CRDSA techniques.
