Adaptive Performance for WoIP Implementation in Cloud Computing Environment

摘要

In this paper we have implemented a real-time video/voice over IP (WoIP) applications on a Hadoop cloud computing system and it is denoted CLC-IHU. It really outperforms the previous WoIP using P2P connection (called SCTP-IHU) due to the easy-to-use and high-performance on video phone call. User does not need to know what is a real IP and web interface achieves interaction by adopt TCP instead of PR-SCTP so taht CLC-IHU scheme reduces computation load and power consumption dramatically at thin clients. We employed adaptive network-based fuzzy inference system (ANFIS) to tune key factors appropriately for adapting handoff and analyzing network traffic at any time. As a result it takes about 1.631 sec for the seamless handoff between base stations under mobile wireless network. In access control for preventing illegal intrusions from the outside of the cloud, the rapid facial recognition and fingerprint identification via cloud computing has been done successfully within 2.2 seconds to identify the subject exactly.
