Retransmission != repeat: simple retransmission permutation can resolve overlapping channel collisions |
Abstract | ||
|---|---|---|
Collisions in overlapping channels are becoming an increas- ingly important problem in the deployment of high-speed wireless networks. In this paper, we present Remap, a sim- ple, novel paradigm for handling collisions in overlapping OFDM channels. Remap introduces the novel concept of re- transmission permutation that permutes the bit-to-subcarrier assignment after each retransmission, departing from the tra- ditional, simply-repeat paradigm. Remap is simple to imple- ment and able to exploit collision-free subcarriers to decode packets despite successive collisions in overlapping chan- nels. We apply Remap to 802.11g to demonstrate that the diversity created by remapped packets can substantially im- prove decoding efficiency and improve wireless throughput. We implement our technique in software radio and demon- strate that it has potential to be deployed with simple soft- ware and firmware updates. |
