Abstract

Handovers in mobile packet networks commonly produce packet loss, delay and jitter, thereby significantly degrading network performance. Mobile IPv6 handover performance is strongly topology dependent and results in inferior service quality in wide area scenarios. To approach seamless mobility in IPv6 networks predicitive, reactive and proxy schemes have been proposed for improvement. In this article we analyse and compare handover frequencies for the corresponding protocols, as they are an immediate measure on performance quality. Using analytical methods as well as stochastic simulations of walking users within a cell geometry, we calculate the expected number of handovers as functions of mobility and proxy ratios, as well as the mean correctness of predictions. In detail we treat the more delicate case of these rates in mobile multicast communication. It is obtained that hierarchical proxy environments – foremost in regions of high mobility – can significantly reduce the processing of inter–network changes, reliability of handover predictions is found on average at about 50 %.
