TDMA A TDMA based resource allocating method in the maritime surveillance networks

摘要

The present invention relates to a TDMA-based resource allocation method in a marine surveillance network for maritime communication, the method being a marine surveillance network system having a network structure between a UBSC and a plurality of UBS clusters, A resource is allocated to a plurality of underwater basestations (UBS) in the cluster in a time division multiple access manner, and a link capacity is ensured such that all the uplink data to the UBSC can be transmitted using one frequency, . According to the present invention, it is possible to prevent a frequency collision in an underwater network of a time division multiple access scheme in which time synchronization between underwater bases is important, and to prevent uplink traffic generated in an underwater base station from being transmitted Since the link resources are allocated, the transmission performance can be improved.
