摘要:
Disclosed herein are a content-based network system and a method of controlling the transmission of content therein. The content-based network system includes a plurality of user terminals, a plurality of access points, a plurality of content origin servers, and a transmission control device. The plurality of access points is wirelessly connected to the plurality of user terminals. The plurality of content origin servers provides content to the access points. The transmission control device determines the priority of transmission of the content based on the characteristics of the content and allocates channels and sets interfaces based on the determined priority of transmission of the content.
摘要:
A wireless mesh network system generates at least one virtual node within a transmission area of a specific mesh node when no mesh nodes exist in two or three continuous quadrants within the transmission area with reference to the specific mesh node. Also, the system performs routing by combining uplink and downlink routing methods so as to support unicast between the mesh nodes in a domain. Further, a channel access order of the mesh nodes is determined based on the potential values allocated to the mesh nodes forming the wireless mesh network according to the field theory. In this instance, the channel access order can be established by a central control method by a central processor for controlling the wireless mesh network or a distributed control method using contention per mesh node.

A communication device operating as a node constituting a multi-hop network in which a plurality of different networks are mixed, a method for detecting a hub, and a method for transmitting a packet are provided. The communication device includes: a hub detection unit configured to determine whether or not the communication device operates as a hub; a pheromone calculation unit configured to calculate a pheromone value according to whether or not the communication device is a hub; a transmission unit configured to broadcast the pheromone value to neighbor nodes; a reception unit configured to receive the pheromone value from each of the neighbor nodes; and a forwarding node selecting unit configured to compare the pheromone values of the neighbor nodes and select a neighbor node having the greatest pheromone value as a forwarding node to which a packet is to be transmitted.

Disclosed herein are a data storage communication apparatus, and data transmission and management methods using the same. The data storage communication apparatus includes a data request signal reception unit, a main control unit, massive storage, and a data transmission unit. The data request signal reception unit receives a data request signal from one of a plurality of user terminals. The main control unit analyzes the data request signal received by the data request signal reception unit, and determines whether data is present in the apparatus itself by searching the apparatus. The massive storage stores and manages a variety of types of data found by the main control unit. The data transmission unit transmits the data to the user terminal. The data is found in the storage by the main control unit.
