We present an analytical model for single-slave Bluetooth piconets when the coexistence of multiple interfering devices produces collisions. Closed-form expressions for the channel throughput and the mean packet delay are obtained, including the time spent waiting on the node's queue. The effect of propagation losses and asynchronous piconets are also discussed. The results of the analysis are validated through simulation.Ministerio de Ciencia y Tecnología TIC2001-1868-C03-02Ministerio de Ciencia y Tecnología TIC2000-0087-P4-0
