The IPv6 over Low-Power Wireless Personal Area Networks (6LoWPANs) standard [3] enables heavily restricted IoT devices (such as wireless sensors) to connect to IPv6 networks. It is interesting to investigate how IPv6-based mobility management protocols, such as Mobile IPv6 and Proxy Mobile IPv6 are implemented on wireless sensors using the 6LoWPAN standard. In this paper, we will describe the n...

In this paper, we describe a transport layer mobility scheme termed Cellular SCTP, or cSCTP for short, based on the Stream Control Transmission Protocol (SCTP), for seamless soft handoff. We compare Mobile IPv6 and two of its variants (Mobile IPv6 with Fast-Handover and Hierarchical Mobile IPv6) with cSCTP on various aspects (especially the handoff process of micro-mobility). We also analyze th...

IPv6 is a new version of the Internet Protocol that was standardised by the Internet Engineering Task Force (IETF). Mobility support in IPv6 is presently being standardised by the IETF Mobile IP Working Group. IPv6 has been designed to overcome all the problems within IPv4 and to provide solutions for the next generation networks. Devices such as Personal Digital Assistants (PDAs) with IP suppo...

In the standard Mobile IPv6, route optimization or bidirectional tunnelling through the home agent show inefficiency in per-packet forwarding, especially when both communicating endpoints are mobile. To be scalable and compatible, mobile devices’ packets should be forwarded in a way with minimal changes to the network infrastructure. However, the current solutions do not provide any means for t...

This paper studies the problems related to mobile connectivity on a wireless environment with Mobile IPv6, specially the handover, which is the most critical part. The main goal of this paper is to develop a structured methodology for analyzing 802.11/IPv6/MIPv6 handovers and their impact on application’s level. This is accomplished by capturing traffic on a testbed and analyzing it with two ap...

In commercial and enterprise deployments, Mobile IPv6 can be a service offered by a Mobility Services Provider (MSP). In this case, all protocol operations may need to be explicitly authorized and traced, requiring the interaction between Mobile IPv6 and the AAA infrastructure. Integrating the Authentication, Authorization, and Accounting (AAA) infrastructure (e.g., Network Access Server and AA...

Proxy Mobile IPv6 is a network-based mobility management protocol. The access authentication security plays the primary role in maintaining network security of proxy mobile IPv6. In this paper, we constructed an authentication framework, which is suitable for proxy mobile IPv6 and has eliminated the interaction between the access network and the home network. We implemented a mutual authenticat...
