Extending Host Identity Protocol with Paging

Host identity protocol (HIP) is mainly designed to provide secure and continuous communication by decoupling the transport layer from the internetworking layer. Furthermore, HIP can provide for a degree of internetworking mobility and multi-homing at a low infrastructure cost. Currently, HIP does not support paging, which is widely used in wireless networks to reduce the signaling cost for location management and to save the power consumption of the mobile node. In this paper, we propose P-HIP, paging extensions for HIP, and discuss the architecture, protocol, algorithm, and the data handling of P-HIP. We develop an analytical model to study the performance of HIP and P-HIP, and discuss the performance results in terms of the signaling cost.
