CSMA/CA protocol shows poor performance for multi-hop transmission due to intra-flow interference (IFI) caused by hidden terminal (HT) problem. We propose an IFI-cancelling (IFIC) multi-hop transmission scheme which can efficiently relay packets under high traffic load and fading environment by using a Known interference cancellation technique. It employs the least mean square (LMS) equalization process of signal reception. A packet frame format dedicated to the proposed IFIC is designed. A theoretical model simulator considering physical layer behavior is created for validation and performance evaluation. The results show that the throughput of the IFIC transmission under Rayleigh fading environment linearly increases with traffic load. When traffic load is high, it has 2.8 times higher throughput than the multi hop network with normal CSMA/CA. When 2-branch maximal-ratio combining (MRC) reception is added after IC, the throughput is further enhanced to 4.2 times higher, which is very close to the theoretical maximum. |
