| Abstract(in English) | We study limits of stability in ad hoc wireless groups of nodes sending each other unicast streams of UDP packets using a CSMA/CA protocol. We show that even in small ad hoc groups where the packet generation rate is constant and below the level for saturation of throughput, there can be large fluctuations in packet arrival intervals due to the intrinsic dynamics of backoff and retransmissions which can occur when doing unicast with CSMA/CA. We show that the conditions for the onset of large fluctuations, and the limits of stable regimes of operation, can be theoretically estimated. Moreover, we discuss the significance of this type of fluctuation on real-time applications such as Voice over IP (VoIP) and network music performances using MIDI. |
