Dynamic Spectrum Sensing Method For Mobile Cognitive Radio Ad Hoc Networks

Cognitive radios are essential concept to transfer from legacy spectrum system to dynamic one. Cognitive radios are brilliant technology, capable to sense the radio environment and reconfigure the system parameters in dynamic network. Cognitive radio network includes multiple features of ad hoc network. These features includes distributed system with multihop framework, opportunistic spectrum system, alternative network topology. Cognitive radio features required to find accurate spectrum portion to successfully deploy cognitive radio ad hoc network. Several users of cognitive network in spectrum sensing cooperative environment detects the active or passive status of primary users. This technique helps to enhance the detection performance of users. Ad hoc network have no central system for data fusion it is crucial to distribute the spectrum sensing network fully cooperative in nature. This study is focus to create cooperative environment based spectrum sensing network for cognitive radio ad hoc networks. The analysis is depends on viewing of reliable sensing and less energy consumption. The contribution of this research is to design context aware framework for distributed system and mobile cognitive radio ad hoc network. This study contribute to avoid Insistent Spectrum Sensing Data Falsification (ISSDF) attacks.
