An important and challenging issue in the next-generation
wireless systems (NGWS) is to support seamless handoff while
moving between different integrated networks. This paper
presents a location aided fast handoff protocol which is an
improvement over the pre-registration low latency handoff
proposed by the IETF. Pre-registration requires layer 2
information that might not be present in the access
technology being used. By processing geographical data
information acquired through GPS related to mobile node
movement and the coverage area of each foreign agent
intelligent handoff decisions can be made, allowing more
control over the actual handoff latency and buffering
requirements.
Key
words:
Mobile IP, seamless handoff, fast-handoff (low latency
handoff), location information, GPS. |
