Interference-aware opportunistic relaying with reactive spectrum sensing

In this paper, we provide low-complexity interference-aware opportunistic relaying (IaOR), suitable for reduced-delay wireless access. In particular, we show that reactive, periodic and distributed spectrum sensing by a set of cooperative relays can offer improved reliability, even in both noise and interference-limited scenarios with low-complexity receivers. This work could potentially assist reduced-delay, high node-density wireless access, as in modern urban environments.
