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)
All IP mobility protocols currently proposed by the IETF assume that the mobile nodes always have a mobility-aware IP stack, which is still a scenario that can seldom be found nowadays. Most terminals, including the laptops and PDAs which would most benefit of the mobility support, still use legacy IP stacks, limiting their use to layer 2 mobility within a(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)
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 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)
