Preserving anonymity and quality of service for VoIP applications over hybrid networks
Zahraa Sabra, Hassan Ali Artail · 2014
In this work we seek to achieve VoIP end users' profile privacy without violating the QoS constraints on the throughput, end to end delay, and jitter, as these parameters are the most sensitive factors in multimedia applications. We propose an end-to-end user anonymity design that takes into consideration these constraints in a hybrid environment that involves ad-hoc and infrastructure networks. Using clusterheads for communication, and encryption of RTP payload, we prove using analysis and OPNET simulations, that our model can be easily integrated to present network infrastructures.
