异构网络管理的综合优化与宏小区的作用
Integrated optimization of heterogeneous-network management and the elusive role of macrocells
摘要：
我们认为异构无线网络的物理干扰模型，并介绍了一个新的配方的混合整数非线性规划问题，解决基站激活和多对多的关联，同时最大限度地降低功耗。我们还介绍了HetNetGA，一个遗传算法，可以解决这个问题，没有任何近似。虽然HetNetGA不适合实际部署，但它能够调查此类网络的真正可能性。涉及宏小区和微微小区的场景的结果通常与预期一致，但有时是意想不到的，并且本质上指出需要更好地理解宏小区在帮助提供容量同时保持能量优势方面的作用。
英文摘要：
We consider heterogeneous wireless networks in the physical interference model and introduce a new formulation of the mixed-integer nonlinear programming problem that addresses base-station activation and many-to-many associations while minimizing power consumption. We also introduce HetNetGA, a genetic algorithm that can tackle the problem without any approximations. Though unsuitable for practical deployment, HetNetGA enables the investigation of such networks' true possibilities. Results for scenarios involving both macrocells and picocells often align with what is expected, but sometimes are unexpected and essentially point to the need to better understand the role of macrocells in helping provide capacity while remaining energetically advantageous.
