Route Optimization Using Collective Binding Update and Mobile Network Prefix for Nested Mobile Networks

Network Mobility (NEMO) supports the movement of some part of network that a group of Mobile Nodes (MNs) or Mobile Routers (MRs) moves together. To support NEMO, the NEMO basic support protocol (NBSP) was proposed (1). In the nested mobile network, however, the NBSP exhibits pinball routing problem. The More nesting level, the problem becomes more serious. In this paper, we propose a new NEMO management scheme using Collective Binding Update (CBU) and Mobile Network Prefix (MNP). It can achieve route optimization and easy to implement. Performance analysis indicates that proposed scheme can reduce packet delay with low processing and signalling overheads. 1
