  • Publication number: 20140380101
    Abstract: The apparatus for detecting concurrency errors of a parallel program for a multicore includes a source code matching module that adds a trace code and a dynamic thread manager class to an input source code based on interleaving information detected from the source code, splits a thread included in the source code to set an interleaving block and executes it, and when an error occurs in the executed interleaving block, the source code matching modules stores log information output from the trace code and information of interleaving block, and stores error information based on the information.

  • Publication number: 20140313967
    Abstract: A multicast routing apparatus in a wireless mesh network and a method thereof are disclosed. The multicast routing apparatus in the wireless mesh network includes: an information obtaining unit configured to obtain group identification (ID) information of neighboring mesh stations corresponding to the respective mesh stations; a selecting unit configured to select a multicast forwarding candidate corresponding to a candidate of the mesh stations capable of participating in forwarding multicast data packet using the group ID information; a tree generating unit configured to generate a tree corresponding to a transmission path of the multicast data packet; and a packet transmitting unit configured to transmit data packet from a transmitting mesh station to a receiving mesh station of the mesh stations using the tree.

  • Patent number: 8799749
    Abstract: Disclosed herein is an ad-hoc multimedia group communication terminal which is robust to packet loss and includes a multimedia transmitter. The media transmitter includes a reception status monitoring module, an error recovery level/traffic adjustment module, a bit stream division and error recovery data generation module, and a media data packet generation module. The reception status monitoring module recognizes packet reception status information relevant to the reception side terminals based on control packets from each of the reception side terminals. The error recovery level/traffic adjustment module adjusts the error recovery level and the amount of traffic of the media data packets. The bit stream division and error recovery data generation module generates error recovery data to be transmitted to the reception side terminals based on the error recovery level. The media data packet generation module generates the media data packets and error recovery data packets.

  • Publication number: 20140043430
    Abstract: The present invention relates to an apparatus and method for providing and controlling multimedia group communication service based on a mesh network. The apparatus for providing a group communication service includes a group communication management module, and an audio and video management module. The group communication management module controls and manages group communication between a plurality of user terminals connected to an internal network independent of an external network. The audio and video management module receives audio and video data for group communication from the microphone and camera of each of the user terminals and manages the audio and video data. The group communication management module includes a packet management unit configured to generate packets that are used to control the group communication, a terminal search unit, and a group communication control unit.

  • Patent number: 7930510
    Abstract: Provided is a method of dynamically reallocating a thread stack in a multi-threaded operating system, and more particularly, a method of dynamically allocating a thread stack of a multi-threaded operating system in an embedded system for wireless sensor nodes. The method includes the steps of: measuring sizes of data and non-data sections of a stack with respect to each thread; determining a new size of the non-data section of each stack based on the size of the data section of the stack measured with respect to each thread; and adjusting the size of the non-data section of each stack to the determined new size. According to the method, even without the source code analysis, an amount of memory spaces to be used can be reduced compared to that of a conventional static stack allocation method.
