Title: A preliminary study on common radio resource management in heterogeneous wireless networks
Abstract: Users equipped with multiple wireless interfaces can get seamless services across heterogeneous wireless networks. If radio resources in heterogeneous wireless networks are managed in integrated fashion, we can handle scarce resources efficiently. In this paper, we present a preliminary study on common radio resource management in heterogeneous wireless networks. First, we propose an integrated network selection algorithm which chooses a target network for newly coming users. Second, an integrated vertical handover algorithm is proposed. When the capacity of a specific network becomes full, some users being serviced in the network are forced to move to another candidate network through our integrated vertical handover. The decision of two algorithms can be made based on the given objective functions which consider various factors such as signal strength, capacity, cost, and current load. The preliminary simulation result shows that the proposed algorithms reduce the blocking probability significantly.
