【摘要】：新一代移动通信网络不断演进为高密集、无定型的异构网络,业务需求与资源供给的匹配问题,即负载均衡问题是异构网络(heterogeneous network,HetNet)资源管理的挑战问题之一。阐述了负载均衡的一般性问题,根据负载均衡算法的主要特征给出了综合分类,按照分类对近年来提出的主要负载均衡策略进行了细致和深入的对比分析;同时也对比分析了几种减少负载均衡过程中信令开销的方案。在总结现有研究成果的基础上,进一步分析负载均衡技术的最新发展趋势,为下一步的研究提出了新的问题和思路。
[Abstract]:The new generation of mobile communication networks have evolved into highly dense and amorphous heterogeneous networks. The problem of matching service demand and resource supply, that is, load balancing, is one of the challenges of heterogeneous network resource management in heterogeneous networks. This paper expounds the general problems of load balancing, gives a comprehensive classification according to the main characteristics of load balancing algorithm, and makes a detailed and in-depth comparative analysis of the main load balancing strategies put forward in recent years according to the classification. At the same time, several schemes to reduce signaling overhead in load balancing are compared and analyzed. On the basis of summarizing the existing research results, this paper further analyzes the latest development trend of load balancing technology, and puts forward new problems and ideas for the next research.
