The most important aspect of cognitive radio (CR) networks is to search, scan, and access the control channel to advertise the free channel list (FCL) amongst the participating CR nodes. Subsequent communication could not take place until there is an access to a well-known and agreed upon control channel to dialogue the initial configuration. In this paper, a novel protocol for searching, scann...

Communication over a quantum multiple-access channel (MAC) with cribbing encoders is considered, whereby Transmitter 2 performs measurement on system that entangled 1. Based the no-cloning theorem, perfect impossible. This leads to introduction of MAC model noisy cribbing. In causal and non-causal scenarios, before input 1 sent through channel. Hence, 2's may inflict "state collapse" for Achiev...

The OR channel provides an unusual opportunity where single-user decoding permits operation at about 70% of the full multiple-access channel sum capacity. The interleaverdivision multiple access technique applied in this paper can approach that performance with turbo and LDPC solutions. The current paper focuses on very low latency codes with simple Viterbi decoding, intended for very high spee...

Wireless Networking is one of the fastest growing areas in the network industry today. Wireless Local Area Networks (WLANs) are gaining special interest as they provide flexibility of location along with low infrastructural and maintenance costs. The hidden terminal problem is unique to wireless networks that decrease the performance of the network. In this paper we propose a new MAC protocol t...
