In VANETs(Vehicular Ad Hoc Networks), moving from one RSU's coverage region to another will bring reauthentication in the new security domain, which can be named security handover problem. In this paper, based on mobility predictability, we propose a novel anonymous communication scheme called SCPT to address the security handover problem. It uses hash chain for vehicle's anonymous authentication...
In delay tolerant networks (DTNs), message ferries exploit controlled mobility to forward messages following specific routes. One of the key challenges is how to design ferry routes to achieve desired connectivity properties and store-and-forward performance. There are some attempts at designing appropriate ferry routes, but the region topology, which denotes the adjacency relationships of ferry regions...
In Hierarchical Mobile IPv6 (HMIPv6) networks, the Mobility Anchor Point (MAP) handles both intra-domain handovers and tunneling traffic for Mobile Nodes (MNs), which is prone to be a single point of bottleneck. In order to increase reliability and flexibility, multiple MAPs are deployed in a management domain. In this case, load balance among MAPs should be carefully considered. Based on the fact...
Measuring the performance of an implementation is important for wide deployment of the fast handovers for MIPv6 (FMIPv6) protocol, which has been proposed to eliminate service interruptions for host mobility or network mobility. In this paper, we implement the FMIPv6 protocol in a real test-bed environment and study its performance in terms of handover latency and packet loss. Link layer triggers...
