A Cognitive Channel Allocation Model in Cellular Network using Genetic Algorithm

摘要

In cellular network, channels are scarce radio resources. These resources are to be utilized judiciously. Though efforts have been made in the past for maximum channel utilization, studies show that effective channel utilization is often not done because of various constraints. The cognitive radio concept suggests that opportunistic channel utilization is possible if the mobile services are classified into two classes. The usage of the channels are based on the cognition that the radio derives. This work proposes a new model that applies a meta-heuristic Genetic Algorithm and the concept of cognitive radio for better channel utilization. The concept of single channel and multi-channel lending is also introduced towards this. Priority is given to the handoff services in comparison to the new services. The performance study, of the model, suggest the effective channel utilization in terms of blocked and dropped services.
