Different Types

Security is a pending challenge in cooperative spectrum sensing (CSS) as it employs a common channel and a controller. Spectrum sensing data falsification (SSDF) attacks are challenging as different types of attackers use them. To address this issue, the sifting and evaluation trust management algorithm (SETM) is proposed. The necessity of computing the trust for all the secondary users (SUs) is eliminated based on the use of the first phase of the algorithm. The second phase is executed to differentiate the random attacker and the genuine SUs. This reduces the computation and overhead costs. Simulations and complexity analyses have been performed to prove the efficiency and appropriateness of the proposed algorithm for combating SSDF attacks.

Power Line Noise

Utilizing power line to transmit information speedily and safely is very important and significant. Whereas, the communication environment and construction of power grid are complex and hostile. The paper introduces the application, common modulation technology—OFDM and noise characteristics of PLC. The paper builds an OFDM input and output system and adds the power line noise into the channel, then compares and analyzes the difference between the OFDM output signals in common channel and PLC channel.
