Abstract

We analyze and compare the performance of two adaptive relaying schemes based on the amplify-and-forward and the decode-and-forward protocols which are employed to improve the performance of collaborative spectrum sensing. As our results show, the proposed schemes allow us to improve the reliability of the communication part of the wireless sensor network. We expect that this in turn will improve the overall sensing performance and the reliability of the spectrum sensing.
