碩士 === 朝陽科技大學 === 資訊工程系碩士班 === 98 === In this dissertation, we propose a method of the Optimization for Distributed Dynamic Channel Assignment of Cellular Network. Simultaneously, we also propose a complete dynamic channel management, selection and reassignment with the consideration of three type of Electromagnetic Compatibility (EMC), 1.Co-Channel (CCC), 2.Adjacent Channel Constraint (ACC), 3.Co-Site Constraint (CSC), respectively. This dissertation consists of five parts, the first part is the introduction of cellular network, then we propose our motivation, related works and structure statement of the dissertation. The second part is to describe EMC, Hand-off process and channel reassignment. The Third part, we introduce channel state, channel state rule, channel state table, channel selection and reassignment. The fourth part, we’ll introduce the execute step of simulation environment, fitness function and Genetic Algorithms, and describe the method of GALC and GASC. Then, we compare GALC with GASC and discuss available channel based, channel selection and channel reassignment schemes, blocking rate of new call and hand-off call. Finally, in conclusion, we could know our method can improve the performance of cellular network effectively through the simulation result.
