Mobile Node Discovery Auxiliary Communication of 6Lowpan

Based on mobility support of IPv6 and node discovery mechanism, this paper proposes a method using node discovery mechanism for mobile node auxiliary connection, in which we detect the real-time received signal strength indicator, by computing and analyzing the change of average value to predict variation trend. In addition, we drew up a new generation of Internet protocol implementation scheme in 6LoWPAN, which is the access of the combination of the mobile node and IoT gateway, etc. In the local IoT, things connect with IPv6, which satisfy the demand of mobility, the whole IoT architecture model of IPv6 connection will be implemented. The analysis and evaluation of network performance was completed in Cooja simulator based on Contiki system after the hardware test. Results show that this method is suitable for the stub network of Internet of things in the common dynamic scenes and more efficient and less packet loss probability when compare to the original 6LoWPAN.
