— In this paper a new protocol for IP mobility management is described, which follows a network-based approach and fulfils the requirements of optimized usage of radio spectrum and minimum involvement of the terminal. The performance of this solution has been analyzed using the OMNeT++ simulator and a comparison with other well known protocols, like Mobile IPv6 and Hierarchical MIPv6, has been carried out. Finally the results of the simulations are presented and discussed in terms of handoff latency, data transport overhead and signaling volume over the air interface. Keywords – IP mobility, network-based mobility management
