the Internet of Things is a rather new concept in IT field. The However, the research of routing protocols of Internet of Things is still a blank, while route designing is an important part in the research of Internet of Things. In this method, we designed a routing method that can take function as routing destination not just nodes. The improvement is more suitable for the use in internet of things, which most unique character is connecting to the internet. Compared with AOMDV in the internet of things, simulation results show that AOMDV-IOT achieves better performance in average end-to-end delay, packet loss and discovery frequency.
