Satisfaction-based handover control algorithm for multimedia services in heterogeneous wireless networks

Abstract

In this paper, we propose satisfaction-based Handover Control algorithm to reduce handover blocking probability as well as increase the revenue of service providers over WLAN and WAAN (Wide Area Access Network). This algorithm utilizes dynamic resource allocation to decrease the blocking probability of vertical handover connections within the limited capacity of system. Based on this algorithm, we derive the handover blocking probability as new traffic load and handover traffic load increase. In order to evaluate the performance, we compare proposed algorithm against traditional non-bounded and fixed bound schemes. Numerical results show that the proposed scheme improves handover blocking probability and increase the revenue of service providers. © 2008 Springer Berlin Heidelberg.
