摘要

为了降低能量消耗，我们提出了一种基于认知蜂窝网络的合作机会频谱接入(OSA)方案，以减少频谱切换的次数。采用三维连续时间马尔可夫链(CTMC)对认知细胞网络中的OSA方案进行建模，并推导出服务等级(GoS)性能指标。通过仿真验证了理论分析的正确性，结果表明了所提出的协作OSA方案的GoS改进。

A cooperative opportunistic spectrum access scheme in cognitive cellular networks

In this paper, to decrease the energy consumption, we propose a cooperative opportunistic spectrum access (OSA) scheme in cognitive cellular networks to reduce the number of the spectrum handoff. A three dimension continuous-time Markov chain (CTMC) is employed to model the OSA schemes in the cognitive cellular networks, and the grade of service (GoS) performance metrics is derived. Simulations are conducted to verify the theoretical analysis, and the results show the GoS improvements of the proposed cooperative OSA scheme.
