METHOD FOR ALLOCATING RESOURCES IN WIRELESS MULTI-HOP NETWORK

摘要

A method for allocating resources in a wireless multi-hop network is provided to combine the multi-hop technology with the D-TDD(Dynamic-Time Division Duplex) system for supporting the asymmetry data service, and to minimize performance deterioration of an uplink caused by CCI(Co-Channel Interference) in a dynamic resource allocating region. A method for allocating resources in a wireless multi-hop network comprises following steps of: receiving a resource allocation request from nodes ranked at a low level and a high level(301); constructing a frame which is divided into a downlink region, a uplink region, and a dynamic resource link region which comprises plural dynamic regions for the down link, the multi-hop and the uplink respectively(302); allocating the wireless resource into each of regions on the basis of the communication channel information(304); reallocating the wireless resource by monitoring the communication channel information between the nodes, so as to minimize the CCI(306).
