Abstract

With the development of the communication network, the cognitive radio becomes good enough to provide the reliable spectrum resources and reliable communications for the secondary users (SUs). This paper considers improving a computer network protocol and then utilizing this computer protocol for secondary users’ (SUs’) information exchanges in cognitive radio. Energy detection is used to find the idle spectrum resource of the primary user (PU). The threshold value can be found out to guarantee that the energy detector can run in the optimal performance. Thus, the physical layer can be built in a good condition. Then the computer network protocol, i.e. UPD, can be utilized for information exchanges between SUs for better spectrum sensing. Simulation results are provided to demonstrate our proposed method.
