In this paper, we present FlexMAC, a wireless protocol development and evaluation platform based on commodity hardware. FlexMAC targets CSMA wireless protocols and allows customization of functions such as backoff, retransmission, and packet timing. We describe our implementation of FlexMAC and quantify FlexMAC's precision for 802.11b compared with commercial hardware implementations. The results show that FlexMAC's performance is very close to that of hardware implementations. We also present two case studies that illustrate FlexMAC's flexibility: the use of opportunistic relaying to boost throughput and an investigation of temporal and throughput fairness. We found that FlexMAC is a useful tool for conducting 802.11-style protocol research. | Source Title: | Proceedings of the Annual International Conference on Mobile Computing and Networking, MOBICOM | URI: | http://scholarbank.nus.edu.sg/handle/10635/146221 | ISBN: | 9781605581873 | DOI: | 10.1145/1410077.1410092 |
