Overview:

In recent years, full-duplex communication technologies have been greatly improved through advanced self-interference cancellation technologies. So far, full-duplex communications have become practical. For a link between a pair of nodes, full-duplex communications can nearly double the spectrum efficiency, and thus significantly improve the network performance. However, in multi-hop wireless networks such as mesh networks, mutual interference degrades performance of full-duplex communications, so high throughput gain cannot be always achieved unless full-duplex links can be efficiently established and managed. In this project, we mainly focus on exploiting concurrent communication opportunities in full-duplex wireless mesh networks: solve the exposed node and the hidden node issues, and allow a half-duplex link to be added to an on-going half-duplex link to form a full-duplex link (either S-link or A-link).
