Abstract
In a general aspect, a method for determining a location of motion detected by wireless communication devices in a wireless communication network includes obtaining a set of motion indicator values associated with a prior time frame. The method also includes generating a prior probability vector based on the set of motion indicator values and comprising values for wireless communication devices connected to the wireless communication network during the prior time frame. The method additionally includes selecting the prior probability vector or one of a plurality of initialization probability vectors based on the set of motion indicator values, a configuration of the wireless communication network, or both. The method further includes using the selected probability vector and a set of motion indicators associated a second, subsequent time frame to identify a location associated with motion that occurred during the subsequent time frame.
