Instance Belated Diffusion, Indoor Jammers


Wireless communication is exposed to signal jamming attacks. Spread spectrum mitigates such problem by scattering narrowband signals over an much wider band frequencies and forcing jammers. In broadcast systems, jammers can easily find out the spread pattern by some receivers. In most wireless networks, nodes can only be limited local information about the state of the network. Wireless networks have the characteristics of broadcast, which brings the nuisance for illegal users to interfere the network or even attack the network. Therefore a series of network problems arise. The open nature of wireless network leaves it to malicious threats. We address the problem of jamming-resistant broadcast communications. For a jamming scene with one transmitter, one receiver and a jammer In the literatures of both eavesdropping and jammer, the threats are caused by the single malicious jammer. In a supplementary analysis, the transmitter and the malicious jammer relay can select the appropriate rate to send signals to increase or reduce the secrecy rate. Wireless networks enable a wealth of commercial, tactical and social applications ranging from single point to point voice communications, information retrieval, monetary transactions, environment monitoring, social networking, navigation and jamming. Many of these applications target users who access the numerous network services via their devices. We propose time-delayed broadcast scheme (TDBS) which makes the broadcast in an unicast communication series. Each node follows an unique pseudo-noise (PN) frequency hopping sequence. We map the problem of constructing PN sequences to the 1-factorization problem for complete graphs. We also accommodate dynamic broadcast groups by mapping the updating the assigned PN sequences.
