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, that is, multiple stream and single stream The multiple stream scheme is simple but can lead to the creation of out of sequence packets As an alternation without out of sequence packets, the single stream scheme consumes extra network resources A new scheme called MPSSF (multiple path single stream forwarding) is proposed in this paper It features less out of sequence over the single stream scheme and remarkable reduction of extra consuming of network resources Simulation results show that fast retransmission triggered by out of sequence packets is avoided in MPSSF, and thus the TCP performance is better than that of the multiple stream scheme or single stream scheme

The method of adaptive hash mapping of weak hop integrity (AHMWHI) was proposed. The main idea is as follows: hash mapping is performed in the datagram during verifying cycle time, i.e. caching the big datagram, and verifying the integrity of other datagram; the state information of datagram sequence and verification information of the big datagram are sent to the next hop router for verifying when the hash table collision occurs; the length of hash table is adaptively adjusted by current network throughput...

The method of adaptive hash mapping of weak hop integrity (AHMWHI) was proposed. The main idea is as follows: hash mapping is performed in the datagram during verifying cycle time, i.e. caching the big datagram, and verifying the integrity of other datagram; the state information of datagram sequence and verification information of the big datagram are sent to the next hop router for verifying when the hash table collision occurs; the length of hash table is adaptively adjusted by current network throughput to make the delay of the big datagram within verifying cycle satisfying the expectation value. Theoretic analysis and experiments demonstrate that the problem that the big datagram packeted with X bytes verification can’t be sent is solved by AHMWHI; the data replay and lose testing functions in weak integrity verification are improved. In demonstrations, the average delay of most big datagram is less than 0.9 ms while the expectation value is set to 5 ms.
