Abstract

This paper presents a novel cooperative spectrum sensing for the performance analysis of the multihop system model. In this paper, the performance of cooperative spectrum sensing is investigated through intensive simulation analysis by means of energy detection over Rayleigh fading distribution in multihop scenario. The closed form expressions for end-to-end SNR PDF of multihop networks over Rayleigh fading channels with different hard fusion methods are analyzed. Based on the framework developed, we demonstrated that in multihop networks, the targeted detection probability achieved is varied with channel SNR values and number of cooperations used.Keywords: Cooperative spectrum sensing, fusion rules, multi-hop system, performance evaluation, Rayleigh fading, cascaded systemsCite this ArticleDeepti Kakkar, Arun Khosla, Moin Uddin.
