This letter proposes a greedy-based dynamic channel assignment (GDCA) strategy in cellular mobile communication networks. Its main feature is that it dynamically allocates the channels based on the greedy method. Instead of the regular hexagon cell shape considered by previous strategies such as BCO, BDCL, various CP-DCA, the new strategy can be applied to any irregular cell shape. In addition, it reuses channels in terms of C/I ratio criteria. By system simulation, the proposed strategy outperforms the still used FCA on call blocking probability, and even has better performance compared to BDCL and CPDCA, etc.
