Abstract: A communication terminal of a wireless sensor network and a communication method thereof are provided to suppress an increase by geometric progression of size of a contention window, even though frequency of attempting to transmit collected packets is increased. When collected packets are transmitted, a contention window of size set in an active section is set(413-419). If channel usage is not possible in the set contention window, another contention window of size linearly or exponentially expanded than the set contention window is reset in the active section(423,431). The resetting process is repeated. When the additional setup process is repeated, the size of the set contention window is linearly expanded into set expansive frequency. If the set expansive frequency elapses, the process of exponentially expanding the size of the set contention window is repeated.

Abstract: A multicast packet processing system and a method thereof are provided to transmit flooding multicast packets after copying the packets within each output board, thereby reducing an amount of internal traffic and loads of reception boards. A VLAN(Virtual Local Area Network) setup unit(401) of a main board(400) sets an Ethernet switch port to one VLAN.

LAG information tables store link aggregation information of an overall system. Plural multicast packet processing/copying units(600-603) copy into plural packets based on the OIF lists.

Abstract: An apparatus and a method for controlling an optical output in an ONU(Optical Network Unit) are provided to operate an overall PON(Passive Optical Network) system stably by preventing an influence of malfunction of a laser diode on other normally operating ONUs. An optical transmission module(310) transmits an optical signal including data inserted into an allocated time slot to an OLT(Optical Line Termination)(100). An optical output control module(330) detects the transmitted optical signal. If the optical signal is detected for longer than a pre-set time, the optical output control module controls to prevent the optical signal transmitted to the OLT. An optical detecting unit(332) detects the optical signal transmitted from the optical transmission module to the OLT. If the detect time of the optical signal in the optical detecting unit is longer than the pre-set time, a controller(334) determines that the optical transmission module malfunctions and prevent an optical output of the optical transmission module.
