Abstract
Cooperative Automatic Retransmission Request (C-ARQ)
schemes allow those users which overhear a transmission to act as spontaneous
relays when a packet has been received with errors at destination.
When these users assist a source-destination pair in the retransmission
process, the area exposed to the original transmission increases in comparison
with non-cooperative ARQ schemes. In addition, the extension of
the transmission time, due to the retransmissions, increases the vulnerability
of a transmission to the hidden terminal problem. The paper provides
a performance analysis of the hidden and exposed terminal effects
in an 802.11-based wireless network where a C-ARQ scheme is executed
at the Medium Access Control (MAC) layer. The presented analysis is
supported by computer-based simulations.Peer Reviewe
