| Abstract: | A cooperative random access protocol, namely alliances,
was recently proposed for resolving collisions in wireless networks.
In [1], we proposed an multichannel extension of alliances
that in addition to cooperation diversity can exploit
multipath diversity, and thus improve throughput at high traffic
load and reduce packet delays. In this paper, we propose an
improvement on [1] that makes more efficient use of available
bandwidth and thus can achieve high throughput at all traffic
loads. Furthermore, we present analytic performance characterization
that provides insight on the relationship between achievable
diversity and parameters like collision order, number of
relays, channel length and number of carriers per subchannel. |
