Abstract: A packet analyzer is a tool for debugging sensor
network systems and is convenient for developers. In this paper, we
introduce a new packet analyzer based on an embedded system. The
proposed packet analyzer is compatible with IEEE 802.15.4, which is
suitable for the wireless communication standard for sensor networks,
and is available for remote control by adopting a server-client scheme
based on the Ethernet interface. To confirm the operations of the
packet analyzer, we have developed two types of sensor nodes based
on PIC4620 and ATmega128L microprocessors and tested the
functions of the proposed packet analyzer by obtaining the packets
from the sensor nodes.
