Load Balancing White Papers
A Dynamic Load Balancing in Wireless CDMA Cellular Networks
Overview With the increase of cellular users the traffic hot spots and unbalanced call distributions are common in wireless networks. The CDMA techniques enables a base tranciever station to connect microcells with optical fibers and to control the channels by sectorizing the microcells. Each sector which covers several microcells is assigned a soft channel capacity. To solve the load balancing among microcells, the microcells are needed to sectorize dynamically depending on the traffic required in each cell. The load balancing problem is formulated as an integer linear program which minimizes the unserved traffics and handoff calls in the network. Genetic algorithms are developed to solve the problem and computational results are discussed by comparing with other methods.
