802.15.4/ZigBee networks comprise several devices that communicate with each other over a wireless communications medium. Each network has a unique ID (PAN ID), and each station (device) has its own unique Device ID. Several networks may coexist in the same proximity, sharing the same RF channel or using different channels. For increased efficiency, a network coordinator station may transmit a repetitive beacon, allocating time slots for network members' transmissions. Such time-related events are difficult to analyze by going over a list of messages with the content (or even time stamp) of each message.
