A Proposed Propagation-Based Methodology with Which to Address the Hidden Node Problem and Security/Reliability Issues in Cognitive Radio

A highly accurate, fast and robust integral equation-based propagation method is presented here. It is explained how this method, in conjunction with a radio environment mapping server can be used to address the dasiahidden node problempsila and salient security/reliability issues in cognitive radio (CR) by accurately quantifying the effects or CR transmissions in realtime thus allaying the legitimate concerns of primary users regarding the deployment of CR technology. A roadmap for the development of the propagation method is given such that sufficient accuracy and execution times can be achieved.
