Performance evaluation of access selection algorithms for VoIP on wireless multi-access networks

The tendency of wireless communication systems beyond 3G is the wireless multi-access (MA) environment, which is characterized by the integration of different radio access networks (RANs). Parallel to the wireless network evolution, Voice over Internet Protocol (VoIP) is one of the fastest growing Internet real-time applications. Implementation of VoIP over a multi-access network requires the incorporation of efficient resource allocation strategies, namely, common radio resource management (CRRM), in order to meet the optimum combined network performance. In this paper, we propose access selection (AS) algorithms for MA networks and evaluate their performance for VoIP service. Conventional AS algorithms are taken as reference.
