Analysis of Secure Real Time Transport Protocol on VoIP over Wireless LAN in Campus Environment
Journal Title: International Journal on Computer Science and Engineering - Year 2010, Vol 2, Issue 3
Abstract
In this research, we propose to implement Secure Real Time Transport Protocol (SRTP) on VoIP services in campus nvironment. Today, the deployment of VoIP in campus environment over wireless local area network (WLAN) is not considered on security during ommunication between two arties. Therefore, this study is to analyzed SRTP performance on different VoIP codec selection over wired. We have implemented a real VoIP network in niversity of Kuala Lumpur (UniKL), Malaysia. We use oftphone as our medium ommunication between two parties in campus environment. The results show that implementation of SRTP is able to improve the VoIP quality between one-to-one conversation and multi conference call many-to-many). In our experiment, it shows that iLBC, SPEEX and GSM codec are able to improve significantly the multi conference (many-to-many) VoIP quality during conversation. In additional, implementation of SRTP on G.711 and G.726 codec will decrease the multi conference (many-to-many) VoIP quality.
