With emerging IPv6-based standards such as 6LowPAN and ISA100a, full IPv6 sensor networks are the next major step. With millions of deployed embedded IPv6 devices, interoperability is of major importance, both within the sensor networks and between the sensors and the Internet hosts. We present uIPv6, the first IPv6 stack for memory-constrained devices that passes all Phase-1 IPv6 Ready certification tests. This is an important step for end-to-end interoperability between IPv6 sensors and any IPv6 capable device. To allow widespread community adoption, we release uIPv6 under a permissive open source license that allows both commercial and non-commercial use.

Future Internet Protocol mobile communications systems will implement solutions for network-based mobility management to enable mobility for terminals, which do not support Mobile IP. The Internet Engineering Task Force is specifying a base protocol for network-based mobility, which supports registration, deregistration and handover. Support for optimization will be considered in a subsequent standardization step. This paper proposes a solution to enable support for route optimization, being under control of the mobility anchor of the network-based mobility domain. The route optimization protocol solution has been specified with the objective to cope with difficult scenarios, which can occur in a network-based mobility enabled system. The protocol has been implemented and evaluated based on a base protocol specification, taking future porting into the final standard base protocol into account. Important characteristics have been obtained from a hybrid test- bed, which comprises physical and virtual network entities. The results show, that the proposed protocol sets up and maintains optimized routes efficiently.

This paper details a novel architecture, MobiSplit [17], for managing mobility in future IP based networks. The architecture separates mobility management in two levels, local and global, that are managed in completely independent ways. We describe how such a mobility architecture can be used to support a new paradigm in mobility. By combining the user's identity with a multi physical virtual terminal we treat the movement of people rather than their physical manifestations in one device. We conclude by analyzing the concrete system, built from this new architecture and existing protocols, in terms of scalability, flexibility and security.
