Disclosed is a conference server included in a system for providing a conference service in RTCWeb, where the system includes a first terminal that operates as a moderator of the conference service and a second terminal that operates as a participant of the conference service. The conference server includes a focus that performs communication between the first terminal and the second terminal; the first terminal includes a conference control server/client that controls a generating of the conference, an adding/removing of the second terminal to/from the conference service, and a changing of a moderator, and manages information of the second terminal; and the second terminal includes a conference control client that acquires information of the conference service and controls a participation/departure in/from the conference service. The focus of the conference server communicates with the conference control server/client of the first terminal to resolve a request of the second terminal.
Abstract:
A method of building an ad-hoc network of a wireless relay node and an ad-hoc network system are disclosed. The method includes verifying state information representing a relative distance and angle to a neighboring node capable of receiving data when each of relay nodes transmits the data, determining an action representing a change over time of each relay node, determining, based on an amount of change in a network throughput determined according to the state information and an amount of energy consumption according to the action, a reward corresponding to the action, and building a network including a source node, a destination node, and a plurality of relay nodes by generating, based on a reward of each of the relay nodes, a policy that allows a cumulative reward to be maximized.
Abstract:
A code sequence based intelligent key code identification method includes extracting Smali code sequence by decompiling an application, vectorizing the extracted Smali code sequence to construct a training dataset, training a deep learning model with the vectorized Smali code sequence to generate a classifier, generating a category classification result using Smali code sequence of a target application as input of the classifier, and identifying and providing important Smali code sequence from which the classification result of the target application is derived. Accordingly, it is possible to objectively evaluate the application using Smali code sequence of the application being actually run.
