认知无线电频谱切换的高效信道选择机制
Efficient channel selection mechanism for CR spectrum handoff
摘要
Abstract
In cognitive radio system, the efficiency of spectrum handoff is always a challenge. To conquer this difficulty, classification and matching scheme is adopted. The users are classified according to their type of services at first, and then a reliable channel evaluation is designed to match the classifications of the users. This spectrum handoff scheme based on classification and matching is efficient when the users’number is large. Simulation results show that the proposed algo-rithm is a viable method of prompting spectrum handoff efficiency, and reducing congestion probability, handoff number and handoff delay.关键词
