ABSTRACT:
An arrangement for avoiding the capture effect in a half-duplex shared network modifies an interpacket gap timer following collision mediation to ensure a station having transmitted a consecutive number of packets defers to another network station, regardless of the outcome of the collision mediation. If a network having transmitted consecutive packets encounters a collision, the network station selectively modifies the interpacket gap interval based on the selected number of slot times during collision mediation. If the networks station selects zero slot times according to the truncated binary exponential backoff (TBEB) algorithm, the network station increases the interpacket gap by two slot times. If the network station selects one slot time during TBEB collision mediation, the interpacket gap is increased from the minimum IPG by one slot time. Hence, a station having transmitted consecutive packets will always defer to another network station following a collision, regardless of the number of slot times selected during collision mediation.
