【摘要】：新一代移動通信網(wǎng)絡(luò)不斷演進(jìn)為高密集、無定型的異構(gòu)網(wǎng)絡(luò),業(yè)務(wù)需求與資源供給的匹配問題,即負(fù)載均衡問題是異構(gòu)網(wǎng)絡(luò)(heterogeneous network,HetNet)資源管理的挑戰(zhàn)問題之一。闡述了負(fù)載均衡的一般性問題,根據(jù)負(fù)載均衡算法的主要特征給出了綜合分類,按照分類對近年來提出的主要負(fù)載均衡策略進(jìn)行了細(xì)致和深入的對比分析;同時也對比分析了幾種減少負(fù)載均衡過程中信令開銷的方案。在總結(jié)現(xiàn)有研究成果的基礎(chǔ)上,進(jìn)一步分析負(fù)載均衡技術(shù)的最新發(fā)展趨勢,為下一步的研究提出了新的問題和思路。
[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.
