In wireless mesh networks, to analyze and debug the current and new protocols, packet-level accurate information of protocol status is crucially needed. Thus, this demonstration introduces PaPMo (Packet accurate Protocol Monitor) system, an active monitoring tool that captures snapshots of the protocol status as packets pass through the different layers. We show that PaPMo is able to correlate MAC-layer events, such as packet loss due to queue overflow, with TCP congestion control behavior with high fidelity.
