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 hierarchical mobile IPv6 (HMIPv6), most of existing MAP selection schemes is mobile node (MN) based, which implements MAP selection on MN side and supposes all MNs use the same selection algorithm. But in practical environment, MNs usually adopt different MAP selection algorithms, which will disorder the MAP selection and make the performance of entire system hard to achieve as expected. Thus,...
The anticipation time has a significant impact on the performance of fast handover, especially predictive fast handover. Predictive fast handover which generally outperforms reactive fast handover requires a sufficient anticipation time to complete necessary operations before the current network is broken. However, the anticipation time may spur packets for the mobile node (MN) to be forwarded to...
