AN INTELLIGENT CHANNEL ALLOCATION SCHEME FOR MOBILE NETWORKS: AN APPLICATION OF AGENT TECHNOLOGY

摘要

As the demand for mobile services grows, techniques for increasing the efficiency of channel usage in mobile networks become more important. Radio resource flexibility is needed to cope with the limited frequency spectrum available for network operators. The frequency channel allocation in mobile networks is a complex control problem with specific goals, i.e., to minimize the call blocking probability of the network and minimize the delay in channel assignment. This paper proposes a multi-agent system implementation to control frequency channel allocation in mobile networks. The internal agent architecture allows base stations to be more flexible and intelligent, negotiating and co-operating with others to improve the efficiency of the channel allocation scheme. The simulation results prove that the use of agent technology in controlling the allocation of channels is feasible and the agent negotiation is an important feature of the system in order to improve perceived quality of service and to improve the load balancing of the traffic.
