Network layer indications are not readily available upon a link change; therefore, general dependence on the network layer may introduce unnecessary delays due to network layer signaling for a simple link layer handoff. If information could be gathered at link layer to determine the need for network layer signaling, then both the delay and signaling load could be really improved over current standards...
Increasingly the access networks will be heterogeneous, and the IP layer, which will be the integrating common layer across the networks, will need to deal with different access topologies. Since different access networks will offer varying bandwidth capabilities, the resulting traffic profiles will be varying as well. Adaptation of (and, to) handoff is one of the keys requirements stipulated by the...
Among the characteristics of the future wireless networks is the desire to support a wide range of wireless users and a diverse set of services from many different types of networks. A unifying technology for diverse wireless networking is mobile IP, a protocol established by the Internet Engineering Task Force (IETF) that allows mobile nodes (MN) to change their point of attachment to the Internet...
