Mobile IPv6 was the IETF proposition to support host mobility in the Internet. However, MIPv6 only defines means of managing global (macro)-mobility but does not address micro-mobility separately. This involves long handover delay and signaling load. To solve this problem, the Hierarchical Mobile IPv6 (HMIPv6) protocol has been proposed by splitting the handover management into inter-domain mobility...
Structured peer-to-peer overlay networks provide a useful substrate for building distributed applications. They map object keys to overlay nodes and offer a primitive method to send a message to the node responsible for a key. Though they work well in homogeneous environment, there are still some challenging problems to be solved when adapting them to heterogeneous environment. This paper studies...
This paper analyzes the problem existed in the overlay and network layer of structured P2P system based on Distributed Hash Table, and considers the mobile characteristic of peers in the mobile environment, we find that the problem become more serious. This paper also describes the influence that the unmatchable problem has acted on the Mobile P2P system. To solve this problem, these methods are considered:...
HMIPv6 remedied the deficiency of mobile IPv6 protocol, reduced the delay and the amount of signaling during handover compared with the basic MIPv6. But duplicate address detection and the transmission time for the handover operation in HMIPv6 could cause high handover delay. So HMIPv6 still cannot reach the requirement for traffic that is delay sensitive, such as voice. Through the analysis of HMIPv6,...
