Research and implementation of multi-frequency band 6LoWPAN accessing to IPv6 internet

This paper proposed a solution of Multi-frequency band 6LoWPAN accessing to IPv6 Internet based on the research of wireless sensor network, 6LoWPAN standard and IPv6 network. Furthermore, combining with the multiplexing technology and the TUN/TAP technology, this paper proposed a uplink and downlink packet scheduling mechanism oriented to the multi-packet concurrency problem and realized it in the embedded Linux gateway. At last this paper did the access test and the throughput test. The results of the tests showed that multi-frequency band 6LoWPAN can access to IPv6 Internet properly and the proposed packet scheduling mechanism makes the gateway have a high throughput.
