Abstract:
A QoS performance improving method of MIL-STD-188-220 wireless network communication protocol and a data frame service node are disclosed. According to embodiments of the present invention, the QoS performance improving method applies a connection function to a plurality of data frames requesting responses in an Ad-Hoc wireless communication network and transmits the response by composing the response with one block response (Block Ack) frame in order to improve the whole performance of the wireless communication network because the wireless communication network treats the more data amount within the predetermined time or reduces the data transmission amount of the data frame requesting the response. [Reference numerals] (AA) Start;(BB) No;(CC) Yes;(DD) End;(S20) Connect multiple frames demanding a response and having the same receiving destination;(S21) Transmit those frames connected;(S22) Reception station ?;(S23) Organize a block response frame;(S24) Stay during a response delay time;(S25) Transmit the block response frame to the receiving destination;(S26) Dash until the block response frame to be completely transmitted;(S27) Operate the same network access scheduler
Abstract:
PURPOSE: A computer readable medium recording data structure thereon including an Hangul code linked with ASCII and an encoder and decoder using Hangul code linked with ASCII are provided to reduce communication load by converting or transceiving Hangul character into 14-bit code value. CONSTITUTION: A code converting module(110) changes an input text into a code value by 2-byte unified Hangul code. A 8-bit dissolving module(120) changes the code value into 8-bit unit bit stream. A 7-bit forming module(130) eliminates the MSB(Most Significant Bit) of the bit stream and converts into 7-bit unit bit stream. If the sum of output total bit number is not a multiplied number of 8, a 8-bit configuration module(140) add 0 to the 7-bit stream and outputs 8-bit unit bit stream.
Abstract:
The present invention relates to a wireless communication network technology, and more particularly, to a Quality of Service (QoS) implementation method for improving Link Quality features selectively offered in MIL-STD-188-220 standard and an ambiguous path quality measurement method by providing DTR (Delay, Throughput and Reliability) properties to select an optimal path which implements the QoS a service requires in a multipath.

Abstract:
PURPOSE: A variable format message processing device and a method are provided to generate an MD(Message Description) file and to automatically generate a software for a variable format message processing device from the MD file, thereby minimizing development manpower for the software. CONSTITUTION: A file generation unit(120) analyzes a table structure of an integrated database, and generates a file which includes a structure and limitation information for a variable format message. A code generation unit(130) stores a token information by parsing the structure and limitation information in a token unit. The code generation unit generates a code which processes the variable format message by processing the token information for each field. The structure information includes a number, a name, a description, a field, an index number, a field name, a field bit size, and a field effect value of the variable format message.
