Abstract:

In some spread spectrum environments, the low energy of the transmitted signals, in conjuction with the existence of channel noise, do not allow the distinction between collision and lack of transmissions. For such environments, and for the Poisson user model, the authors propose and analyze stable full feedback sensing and limited feedback sensing synchronous transmission algorithms. They assume binary SNS success versus nonsuccess feedback per slot, and the possibility of transmission of phony data by a central node. The highest throughput attained by both the full feedback sensing and the limited feedback sensing algorithms is 0.322, while the latter induces somewhat higher delays. This is compensated by the robustness of the limited feedback sensing algorithm in the presence of feedback errors in contrast to the full feedback sensing algorithm and its modest requirements on the sensed feedback history.
