Optimal power allocation in multi-hop cognitive radio networks
2011 IEEE 22nd International Symposium on Personal, Indoor and Mobile Radio Communications, 2011 Optimal power allocation in a multi-hop cognitive radio network is investigated. Information transmitted from the source passes through several wireless relay nodes before reaching the destination. At each hop, the received signal is decoded, re-encoded and retransmitted to the following node.
