While inherently a broadcast protocol, BRNs can support unicast transmission by superimposing a plurality of controlled barrage regions (CBRs) onto the network. ...
Using this accurate analytical framework, a line network is optimized, which identifies the code rate, the number of relays, and the length of a radio frame that maximizes the transport capacity. ...
The spatial extent of unicast and multicast transmissions can be contained in BRNs via controlled barrage regions (CBRs). ...
