In this paper, a novel wireless cooperation scheme with complex-field network coding (CFNC), CFNC-amplify-and-forward (CFNC-AF), is developed for multi-way relay (MWR) communications. In this scheme, orthogonal CFNC vectors and joint signal detection are employed to accomplish information exchange among N(N > 2) user nodes via a helping relay node, and a multi-phase transmission protocol is designed...
LDoS (low-rate denial of service) attack is periodic, stealthy, and with high efficiency, which has become a great threat to the network security. Previous researches about LDoS attack mainly focus on its impact on wired networks. However, our analysis shows that such attack could also be launched in ad-hoc network, and as a completely distinct MAC layer protocol is adopted in this environment, the...
