In shared wireless medium access, receiver initiated busy burst (BB) transmission mitigates the problem of co-channel interference. Receiver feedback allows potential transmitters to ascertain the amount of interference their transmission would cause to victim receivers in adjacent communication links. The BB concept mitigates excessive co-channel interference, by maintaining an exclusion region around any victim receiver: interferers within the region must refrain from accessing the shared wireless medium. In this paper, an analytical framework for interference modelling of the BB protocol is developed, via cumulant-based shifted log normal approximation of its probability density function (pdf). The interference pdf is then applied to derive the pdf of the signal-to-interference ratio (SIR).
