Performance analysis of streamed video over mobile IP based networks

In mobile IPv6, packet transfer is interrupted due to the handoff of a mobile node, which results in burst packet loss. This transient behavior decreases the required quality of services for time-critical streaming media applications. This paper introduces an analytical model of streamed video over mobile IP networks considering the effects of handoff. The proposed model focuses on the effect of the frame error rates on the handoff latency of multimedia traffic. It is derived based on general distribution for the residence time to be applicable in all cases of user mobility. The impact of the behavior of wireless connection, cell residence time and the handoff time is investigated. Numerical results are obtained for video traffic presented by Gamma distribution for transmission behavior. It is shown that, a higher value of frame error rate increases the probability of erroneous packet transfer. A shorter video time leads to end this connection most likely in first foreign agents while a longer one leads to larger delivery time.
