Abstract: A system and a method for beacon scheduling for preventing beacon collision are provided to select a beacon transmission time efficiently when the routers of a sensor network are activated and allow a sink node to manage the entire beacon collision of the routers, thereby constructing the sensor network environment of a beacon mode with stability, low energy consumption, and high performance. A method for beacon scheduling for preventing beacon collision comprises the following steps of: allowing all router nodes to transfer messages including received slot numbers and beacon scan completion times to a sink node(S420); allowing the sink node to check whether there is the same slot number in the messages transferred from the router nodes(S440); updating the scan time of a corresponding slot number entry of a table when there is no same slot number in the messages(S440); considering that two routers have a change of beacon collision if the two routers use the same slot and a scan time interval is less than or equal to N*beacon interval(N=1,2,3,4,...)(S460); and applying a reset command to a router which transfers a slot allocation message recently out of active routers(S470).

Abstract: A beacon scheduling method in a wireless sensor network is provided to support a more stable communication environment by avoiding beacon collision between neighbor routers, and enhance utilization of sensing data . An event generation node receives beacons from a PAN coordinator and neighbor nodes such as neighbor routers and recognizes super-frame slots used by the neighbor routers and parent routers of the neighbor routers(301). The event generation node determines its parent router by using beacon information obtained from received beacons(302). The event generation node obtains its routing depth information based on address information of its parent router and recognizes the number of available beacon slots in a super-frame duration(303). The event generation node checks whether beacons, starting the right beacon slot, are being used by other routers(304). If a beacon slot is not used, the event generation node determines the corresponding beacon slot as an optimum beacon slot(305). The event generation node transmits sensing data to the parent router in the super-frame duration of its parent router(306).

Abstract: PURPOSE: An operator interfacing method in HANbit ACE64 exchange to provide a compatibility with a heterogeneous operating system is provided to easily connect to various types of operating system or network management system by allowing the exchange to provide an interface that has high portability and utility. CONSTITUTION: A network management system makes a CORBA(Common Object Request Broker Architecture) client(S1), and then activates a corresponding command receiving server(S2). At this time, a CORBA server performs the activated and called CORBA operation(S3). The performed result is transferred to an input command generating part(S4), and an IMD(Input Command) is created(S5). The created IMD is transferred to a corresponding block in the exchange and performed(S6-S8). The performed result is transferred from the function block to OMP(Operation and Maintenance Processor)(S9) and transmitted to an output message interpreting part(S10). The output message interpreting part interprets an OMD(Output Command) and extracts parameters to be used in assembling CORBA IDL by a message transmitting CORBA client(S11). The extracted parameters are transferred to the message transmitting CORBA client(S12). The message transmitting CORBA client assembles the corresponding IDL(S13) and calls a corresponding CORBA server in the operating system(S14).
