ABSTRACT
Despite decades of research on interference-oriented channel access scheduling, most existing literature are either based on the physical interference model or the protocol interference model, neither of which is a good foundation for distributed interference control in the presence of uncertainties [2]. To address the issue, Che et al. [2] have identified the physical-ratio-K (PRK) interference model that integrates the protocol model's locality with the physical model's high-fidelity. Given a transmission from a node S to another node R, a concurrent transmitter C is regarded as not interfering with the reception at R in the PRK model if and only if P(C, R) < P(S,R)/KS,R,TS,R, where P(C, R) and P(S, R) is the strength of signals reaching R from C and S respectively, KS,R,TS,R is the minimum real number chosen such that, in the presence of interference from all concurrent transmitters, the probability for R to successfully receive packets from S is no less than the minimum link reliability TS,R required by applications (e.g., control algorithms).
