| Abstract: | 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. |
