For Web-based applications in Internet of Things (IoT) environment, the IETF CoRE Working Group developed the Constrained Application Protocol (CoAP). A limitation of CoAP is that it does not address a mobility management for CoAP sensor nodes, which may move between different IP domains of a wireless sensor network. In this paper, we propose the CoAP-based Mobility Management Protocol (CoMP), which...
Most of the current mobility management protocols such as the mobile IPv4 or mobile IPv6 and its variants standardized by the IETF do not support global seamless handover. This is because they require comprehensive changes in the existing network infrastructure. In this article, we propose a simple mobility management protocol (SMMP) which can support global seamless handover between homogeneous or...
This letter presents a fast IP mobility management scheme in vehicular networks where multiple wireless network interfaces are used to perform the fast handover without packet loss. In order to do that, the IETF standard HMIPv6 has been extended, where multiple simultaneous tunnels between the HMIPv6 MAP and the mobile gateway are dynamically constructed. The architecture for supporting multiple tunnels...
Recently, there appear diverse smart phones with dual wireless interfaces such as Wi-Fi and 3G. In this article, we present a novel IP mobility management scheme in which dual wireless network interfaces are assigned active IPv6 Care-of-Addresses and used simultaneously for achieving fast handover without packet loss. In order to do that, the IETF standard HMIPv6 has been extended such that while...
