Abstract: The Internet of Things (IoT) is envisioned to adapt massive of devices accessing or exiting and frequent network changes, which brings lot of pressure to nodes management. Structured P2P network can effectively relieve this pressure. But most P2P networks simply support to search node with node ID. This paper improves Distributed Hash Table (DHT) and realizes searching and managing with node properties and range of properties. Based on improved DHT, this paper realizes a new kind of IoT resource discovery system. This system could organize all kinds of resource in IoT and form a distributed and loosely coupled system for IoT system. Experiment showes the search system could realize effective nodes search in distributed IoT.

Key words: Internet of Things, structured P2P, things discovery, distributed hash table
