There have been increasing demands for research into multi-channel-based wireless sensor network protocols and applications\nto support requirements such as increased throughput and real-time or reliable transmission. Researchers or developers of these\nprotocols and applications have to simultaneously analyze the exchanged packets for correctness of both their contents and message\nexchange timelines. However, if developers were to use multiple conventional single-channel packet sniffers for this purpose,\ndebugging during development and the verification process becomes extremely tedious and difficult because of the need to check\nthe correctness of the protocols over multiple channels individually. Therefore, we present a multi-channel packet-analysis system\n(MPAS) that helps in debugging and verification for multi-channel protocols or applications. Wireless packets are detected and\ntime stamped by each sniffer module in the MPAS for each channel, and packets are pre processed and transmitted to a GUI-based\nanalyzer, which then parses the received packets and shows them in order.We present the design and implementation results of the\nMPAS and evaluate its performance by comparing it against a widely used packet sniffer.
