All the proposed IP mobility protocols assume that the mobile nodes always have a mobility-aware IP stack. On the other hand, efficient micro-mobility solutions entail specific topologies and mobile-aware routers, requiring major changes in the existing infra-structures. Major advantages are foreseen if mobility can be supported using the existing legacy(More)
In the field of mobility support, several mobility protocols resort to the use of triangulation mechanisms as a means of supporting fast handovers or basic connectivity. In order to reduce the maximum end-to-end delay of the packets, such triangulations can be later removed to enable direct routing of the data packets. However, using a simple update of this(More)
This paper describes a Terminal's Independent Mobility Architecture, TIMIP / sMIP, which supports IP mobility of legacy terminals, and presents a complete performance evaluation to compare the proposed architecture with alternative solutions, via simulation studies in complex scenarios featuring wired mesh topologies and wireless disjoint channels. The NS2(More)
This paper describes a local Route Optimization (RO) scheme applicable to IP micro-mobility protocols, which increases the protocols' efficiency and scalability while maintaining their fast-handovers capabilities. This is done by reducing and decentralizing the chain of agents that participate in the data forwarding to stationary mobile nodes. This generic(More)
