The design of mechanism is used to calculate node reliability of incredible P2P network. The mechanism through matrix shows the trust relationship between nodes in the network, through matrix operation realizes the trust transfer process fast, and through a trusted server provides calculation service of trust degree for nodes in P2P network.

Agricultural IOT (Internet of things) is the integration of modern information and communication technology in agriculture. Based on 6LoWPAN wireless sensor networks, this paper puts forward a real-time monitoring system to agricultural environment, in order to improve the function of modern agricultural greenhouse control system. This system uses the 6LoWPAN as backbone to reach the goal of point-to-point communication between NGI (next generation Internet) and wireless sensor networks signed with IPv6. It is no specific gateway to protocol transition and carrying which makes it possible to realize real-time monitoring and controlling of agricultural environment, reduce energy consumption, shorten the delay time.
