An Adaptive Network Mobility Support Protocol in Hierarchical Mobile IPv6 Networks

摘要: The network mobility (NEMO) basic support protocol provides collective for a group of nodes in vehicular area networks. Since the NEMO always performs same operations, regardless mobile network's characteristics, it cannot achieve optimal performance. We propose an adaptive based on hierarchical IPv6. proposed jointly optimizes binding update (BU) traffic and tunneling overhead by employing BU strategy, depending session-to-mobility ratio (SMR). Specifically, both router (MR) visiting (VMNs) configure two care-of-addresses: 1) on-link care-of-address (LCoA) 2) regional (RCoA). If SMR is lower than predefined threshold, MR VMNs perform RCoA LCoA procedures to their home agents (HAs), respectively. Otherwise, are conducted VMNs, Via analytical models, we evaluate performance against other protocols derive threshold. Numerical results demonstrate that valuable solution promising applications.
