A Study of Load Balancing in Distributed Wireless Communication System

提出了负载均衡在分布式无线通信系统信号处理资源管理中的应用方法,给出了负载均衡域的划分依据,即域内处理节点呼损概率的方差大于某一定值.指出了负载的评价、均衡的粒度及策略的选择方法.通过分布式时间驱动算法的仿真验证了负载均衡的效果及均衡域的划分依据.

Load balancing is proposed in the distributed processing network (DPN) layer of the distributed wireless communication system (DWCS) to manage the signal processing resources. The flat topology of the DPN is divided into hierarchically arranged load balancing domains (LBD). The rule that in one LBD the variance of the call loss probability is greater than a constant should be followed when dividing DPN into LBDs. The evaluation method of load, the granularity and the policy of load balancing are given. By the simulation of the distributed time-driven algorithm, the efficiency of load balancing and the division method are proved to be acceptable.
