Abstract:

A new traffic transferring based multi-cell load balancing (MLB) scheme is proposed. By multi-cell cooperation, MLB carries out one or two hops traffic transfer among the busy cell and its neighbors and achieves load balancing effectively. A multi-dimensional Markov chain based model is also built for MLB to analyze the system call blocking probability. Simulation verifies that MLB decreases hot cell and system call blocking probabilities greatly comparing to available schemes.

Key words: cellular networks, multi-cell load balancing, call blocking probability, traffic transfer
