Paging is a well established technique to reduce signaling cost in mobile devices. Different proposals in literature have shown the implementation and improvement of mobile IP with paging. Here, the authors propose P-SIGMA, an improved and signaling cost-effective version of SIGMA, an IP diversity based end-to-end mobility scheme. They show that with all the benefits of end-to-end mobility management scheme like SIGMA, P-SIGMA, as a mobility management scheme, is more efficient in terms of location management and is more cost effective in terms of signaling load.
