The close conceptual relationship between research and the pharmaceutical industry has lead to physical cooperations between research institutions and industrial laboratories.
Instead of relying on the installation of multiple antennas on one wireless device, cooperative transmission achieves spatial diversity through physical layer cooperation.
Are there new ways to defend wireless networks through physical layer cooperation?
This is the advantage of physical layer cooperation from the security point of view.
Physical layer cooperation serves as an enabling technology for such a change.
It is clear that physical layer cooperation is largely uncharted territory, especially with regard to implementation in practical systems.
In this paper, we investigate the security issues related to cooperative transmission from three angles: vulnerabilities analysis of traditional cooperative transmission schemes; design of the trust-assisted cooperative transmission scheme that is robust against attacks; and illustration of the potential advantage of physical layer cooperation against wireless jamming attacks.
There is a significant amount of work devoted to analyzing the performance gain of cooperative transmission, to realistic implementation under practical constraints, to relay selection and power control, to integrating physical layer cooperation and routing protocols, and to game-theory-based distributed resource allocation in cooperative transmission.
Furthermore, the healthcare providers were trained in adopting self management action plans, including early recognition and treatment of exacerbations, encouragement of regular exercise and guideline based physical reactivation, cooperation with secondary care, and instructions in nutritional support.
