Abstract:
|
This paper provides details and performance evaluation
of the implementation of the Persistent Relay Carrier Sensing
Multiple Access (PRCSMA) protocol for Cooperative ARQ
(C-ARQ) scenarios using off-the-shelf wireless cards. The underlying
idea of PRCSMA is to modify the basic rules of the IEEE
802.11 MAC protocol to execute a distributed C-ARQ scheme in
wireless networks in order to enhance their performance and to
extend coverage.1
For the implementation, we modify the HostAP driver for offthe-
shelf air-interfaces. HostAP is a Linux based driver for
802.11b WLAN cards based on Intersil´s Prism 2.5. Performance
evaluation tests provide proof-of-concept of the efficiency, in
terms of mean delay, of the PRCSMA in realistic conditions |
