Abstract: Under a deeply analysis on the resource features in the IOT, a conclusion is drawn that the
architecture and information discovery service based ONS proposed by EPCGlobal do not apply to the
IOT (Internet of Things). In recent years, many research results show that structured P2P technology
10 has a prominent advantage on information discovery service. In this paper, we come up with a new
model of resource discovery based on P2P, and described in detail in the following aspects: new
identification of things, network architecture, and resource dynamic discovery algorithm based on the
new architecture. We believe this model is helpful for the development of IOT, and finally simulation
results show that the algorithm has high efficiency.
