Abstract
A method that incorporates teachings of the subject disclosure may include, for example, obtaining data relating to a set of collision events on a shared channel on a wireless network according to a contention-based access protocol in which a plurality of terminals attempt to access the channel contemporaneously. A probability of collision in the channel is estimated and a probability distribution of time intervals between access attempts is generated based on the estimated probability of collision. Empirical and theoretical cumulative distribution functions for the time intervals are calculated, and compared to identify a malfunctioning terminal not operating in accordance with the protocol. Other embodiments are disclosed.
