MPSSF: a buffering & forwarding handover scheme reducing out-of-sequence packets

In order to minimize packets loss during handover, fast handover technique as well as packet buffering & forwarding techniques are adopted by micro-mobility protocols in All-IP wireless mobile network. There are mainly two kinds of buffering & forwarding schemes, multi-stream and single-stream. The multi-stream scheme is simple but can lead to the creation of out-of sequence packets. As an alternation without out-of-sequence packets, single-stream scheme consumes extra network resources. A new scheme called MPSSF (Multi-Path Single Stream Forwarding) is proposed in this article. It features less out-of-sequence as single-stream scheme, but extra consuming of network resources is reduced remarkably.
