Abstract :
We examine the secrecy outage of primary links in cognitive wireless sensor networks with interference from secondary users, offering original and highly accurate expressions for the aggregate interference with fading and shadowing. It is found that the presence of shadowing has a significant impact which can swiftly increase secrecy outage. The expressions derived can also be used to obtain other analytical results such as secrecy rate and secrecy transmission capacity.
