FAIRNESS IN WIRELESS MICROCELLULAR NETWORKS

In the design of cellular and microcellular telecommunication networks , it is common to consider service to subscribers in specific regions by more than a single base station. Although the service overlap provi des certain advantages, such as performance improvement achieved in dy namic channel assignment, it results in a large variance in the qualit y of service across the cells, In this paper, we introduce channel res triction to achieve fairness in the network quality of service. We dev elop analytical and simulation models for network performance and exam ine the advantages gained in increased system throughput and reduced p robability of handover failure. The numerical results indicate that re stricting the number of available channels to users in the overlap reg ion results in considerable improvement in the carried traffic and mea n probability of blocking, Finally, we discuss the possibility of subs tituting or scaling down the guard channels with channel restriction t o achieve the desired effect of reduced forced termination.
