RESOURCE ALLOCATION APPARATUS AND METHOD OPTIMIZING SESSION ALLOCATION FOR WIRELESS NETWORK

The present invention relates to an apparatus and a method for resource allocation in a multichannel multisession wireless network. The method comprises the following steps of: calculating a broadcast rate of each transmission node for each of multiple transmission sessions and multiple transmission channel; and allocating a channel to each node and allocating resources to each session. According to the present invention, network utilization can be improved by calculating a flow control coefficient of each transmission session, link costs of each link, and a congestion price of each node in a multichannel multisession wireless network environment, and preferentially allocating resources to an optimal unicast session based on the calculations.
