✦ Synopsis

We consider the problem of random access communications over a time slotted channel with feedback of infinitely multiplicity at the beginning of each collision resolution interval (CRI), i.e., users know via instantaneous feedback the number of users involved in that collision. Once this is known, the resolution algorithm (CRA) operates with binary (successful / non successful, s/ns) feedback. The analysis of this simple hll feedback sensing window random access algorithm, named ideal window stabilized ALOHA, (IWSA). algorithm, provides a throughput of 0.5053 packetslslot. Its delay is also analyzed and compared with similar algorithms.
