Since mobile computing is getting more widespread, providing QoS guarantees and mobility support for Internet devices has become a hot research topic in the next generation Internet technologies. This paper proposed a scheme by extending RSVP to further improve wireless QoS guarantees in HMIPv6 based networks. The key features of the scheme include dynamic resource reservation, priority, pre-registration,...
The coupling of signaling protocols for mobility management and resource reservation plays an important role to achieve quality-of-service (QoS) in mobile environments. When performing a handover, request and allocation of resources have to be done in the shortest possible time to avoid disruptions for the user service. In this paper, we analyze the effects of node mobility on the interaction between...
Multi-protocol label switching (MPLS) is deployed in the Internet backbone to support service differentiation and traffic engineering. Mobile MPLS is a new scheme that integrates Mobile IP and MPLS protocols to support mobility to MPLS. However, it is not suitable for micro-mobility environments. In this paper we propose a micro-mobility architecture based on the integration of MPLS for wireless networks...
Traditional workflow management systems (WfMS) is hard to meet the requirements of the dynamic, flexible modern business process. In recent years, Web services technology has been developing. It not only makes the activity in workflow by Web services form, but also workflow itself is invoked by Web services, especially semantic Web services technology is developing, which makes it possible to compose...
The resource reservation protocol (RSVP) can provide QoS due to its bandwidth guaranteed capacity. However, RSVP faces many challenges in mobile IP networks. In this paper, we propose a set of extensions such as employment of the reservation message, utilization of teardown message and extension of the mobile IP message to optimize the operation of the RSVPv2 protocol in mobile IP networks. The suggested...
Internet engineering task force (IETF) has proposed hierarchical mobile IPv6 (HMIPv6) in order to reduce a frequent location registration of a mobile node in mobile IPv6 (MIPv6). HMIPv6 reduces the amount of signaling and improves the performance of MIPv6 in terms of handover latency. However, less comparative studies have been done to study the performance of the hierarchical Mobile IPv6 protocol...
