摘要： Provided is a method of determining an operation mode of a node in an ad hoc network. The method includes: monitoring a measured amount of residual energy of the node and comparing the measured amount of residual energy of the node with an amount of residual energy theoretically calculated for the node; identifying an amount of information in a queue included in the node; calculating a relay probability of the node by reflecting the identified amount of information in the queue and the result of comparing the measured amount of residual energy of the node with the theoretically calculated amount of residual energy for the node; and determining the operation mode of the node to be one of a relay mode and a transmission mode, based on the calculated relay probability of the node.

摘要： In a resource allocation method in a multicarrier-based mobile communication system that includes base stations and supports multiple access of a plurality of terminals identified using codes, the service area of each base station is divided into at least two virtual cells having different radii about the base station, and resources are actively allocated to terminals located in the service area according to distribution of the terminals in the virtual cells. The service area is divided into two virtual cells based on the received signal strengths of the terminals for a specific subchannel, and the specific subchannel is allocated to one terminal or at most two terminals according to distribution of the terminals in the virtual cells.

A relay node included in the communication system may generate a relay packet by applying a network coding scheme to a hierarchically modulated source packet and to a destination packet received from a destination node. The relay packet is transmitted to a source node and a destination node, and the source node and the destination node may extract a desired packet from a relay packet. The communication system also may adaptively determine an optimal communication mode.
