Load Balancing Apparatus And Method In Wireless Network Hotspots
First Claim
1. A load balancing apparatus for wireless network hotspot, said wireless network hotspot having a plurality of access points (APs) and a plurality of STAs, applicable when any said AP unable to admit a quality of service (QoS) request of any said STA, said apparatus comprising:
- a resources allocation module, for establishing a resources model and relation between said APs and said STAs, and finding a load balancing shift path (LBSP); and
a load balancer, for re-allocating network resources and dynamically adjusting the loads of said APs based on said LBSP.

Abstract
Disclosed is a load balancing apparatus and method in wireless network hotspots, which comprises a resource allocation module and a load balancer. The resources reallocation module establishes the resources module and the relationship between access points (APs) and STAs in the wireless network hotspots, and seeks possible load balance shift paths (LBSPs). From these possible LBSPs, an LBSP is selected. Based on the selected LBSP, the load balancer reallocates network resources and dynamically arranges the load among the APs in the wireless network hotspots. This invention can be applicable to a centralized or a decentralized wireless communication system.
