Abstract
Location/identity separation can be used to enhance mobility in satellite networks. However, given the high mobility of non-geostationary satellite networks, usage of conventional binding update schemes will inevitably result in a large number of binding updates. In this work, a novel virtual attachment point based indirect binding scheme is proposed to address this issue. Moreover, a multi-layer service area based vertical update scheme is further investigated to eliminate the ping-pong effect. A random walk model based analysis and a Monte carlo method based simulation are conducted to evaluate our schemes. And the evaluation results demonstrate the validity and efficiency of our schemes comparing to conventional scheme, i.e. mobile IP.
