Abstract:
1. A packet-based network analysis system for analyzing packet flow among devices in a ZigBee wireless network, comprising: a wireless network analysis processing device configured to: wherein: the packet flow data comprises packet flow records, and the wireless network analysis processing device is further configured to: create a new packet flow record and add packet flow data corresponding to a first hop of a packet in the network if the source MAC address matches the source network address in a corresponding correlated packet record; add packet flow data corresponding to a last hop of a packet in the network to a packet flow record if the destination MAC address matches the destination network address in a corresponding correlated packet record; and add packet flow data corresponding to an intermediate hop of a packet in the network to a packet flow record if the destination MAC address does not match the destination network address and the source MAC address does not match the source network address in a corresponding correlated packet record.
