Abstract


With the rapid growth of the Internet, new applications and services are continuously being proposed for the telecommunication systems. Voice over Internet Protocol (VoIP) is one of the most prominent models for enabling convenient, high-rate, and on-demand voice conversation services through any IP-based network. The increased use of VoIP as an accepted communication form has resulted in a growing volume of academic research dedicated to their assessment.
This study integrates the key-route main path analysis approach and edge-betweenness clustering technique to analyze the knowledge diffusion structures in VoIP domain. The former reveals a roadmap of VoIP including the overall development trajectory and the linkage among different research groups. The latter technique uncovers five major research groups in the VoIP-related literature: wireless network, quality of service, security, traffic and capacity, and VoIP services and architecture. The findings derived from this study highlight the significant development trajectories and contributors of VoIP-related studies.
