Cell Breathing in CDMA Networks

The widespread deployment of wireless cellular technology affects the traditional concept of channel allocation and drives the necessity for novel load balancing techniques. Various load-balancing schemes have been proposed to assign channels to the cells such that the available channels are efficiently used and thus channel reuse, maximized. This is particularly important in networks where traffic distribution is non-uniform. Some of the well-known load-balancing schemes include the Directed Retry (DR), Channel Borrowing (CB), Channel Borrowing without Locking (CBWL), Load Balancing without selective borrowing (LBSB), Cell Breathing and a number of others. Each possesses both virtues and drawbacks. The objective of the paper is to provide an assessment of the capabilities of Cell Breathing in optimal CDMA network management. The paper studies the capabilities of cell breathing, its flaws and suggests possible solutions to the predicament.
