Abstract: Mine Internet of Things can be divided into 3 layers: sensing layer, network layer, application layer. Multi-functional gateway of Mine Internet of Things works at the edge of the network layer, and it both has access and transmission functions. It can make use of various communication media like optical fiber, cable and radio waves. It also adapts to a variety of protocol interfaces like industrial ethernet, WiFi, ZigBee、CAN, RS485, RS232 and so on. It can convert information of sensing layer into ethernet data which can be transmitted by Gigabit fiber ring network.

Abstract: In the campus WLAN wireless networks, transfer speed of network data is attracted great attention of users. How to solve conflict problem occurred in the network data transmission process has become the main goal of the campus WLAN network optimization. This paper presents campus WLAN wireless networks conflict resolution based channel mapping anti-collision algorithm. According to the amount of data to be transmitted in the network, the data length is estimated to provide conflict resolution with support data. On the basis of the channel mapping anti-collision algorithm related theory, conflict resolution model is established. Experimental results show that the proposed algorithm used in resolving conflict in campus WLAN wireless network can reduce the probability of data conflict happened in channel, so as to improve the performance of campus WLAN wireless network.

Abstract: With the development of Internet, various Internet-based large-scale data are facing increasing competition. With the hope of satisfying the need of data query, it is necessary to use data mining and distributed processing. As a consequence, this paper proposes a large-scale data mining and distributed processing method based on decision tree algorithm.

Abstract: In order to popularize the intelligent monitoring in households, this thesis is aimed to conduct researches on“Household Monitoring System based on the Internet of Things (IOT)”and starts with the design of this system. General technology concerning household video monitoring and home appliance controlling in computers, mobile phones, etc. is explored in this thesis and a household monitoring system based on IOT is set up. According to experiments, the household monitoring system has various functions such as operating once plugged, ad hoc network, various and interactive controlling methods and friendly serial ports.

Abstract: Routing information release is a kind of promise from the router for network reachability. Illegal routing information may have disastrous effects on the normal work of the network. Open Shortest Path First (OSPF) protocol provides authentication methods to protect the authenticity and integrity of the routing traffic. This paper describes two authentication types of OSPFv2, analyzes the realization mechanism and packet header format of each authentication respectively. Based on GNS3, a typical network topology was designed, and with the aid of it functional verification and security analysis are carried out. The simulation can provide a reference for building an OSPF network. Experimental results show that the configuration of OSPFv2 routing authentication can effectively prevent the router from receiving unauthorized or malicious routing updates, thereby improving network safety.

Abstract: We use hierarchical data mining to compress the mobile communication data, which improves data transmission rate of 3G mobile internet. Based on this, combining the advantages of VC and MATLAB, we design the digital library architecture of 3G mobile internet model. This model has the functions of inquiry, backstage management, and mobile data optimization and so on. In order to verify the effectiveness and reliability of the model, we use network testing of small digital library as an example to test the library query function with mobile phone. By using the Android test terminal we get the library query process curve and the data flow transmission characteristics. It provides technical support for 3G on mobile internet technology and innovative design of library.

Abstract: Mobile computing environment is relatively complex, and the structure dynamic degree is high, and the heterogeneous is changeable. Therefore, the development of mobile network based on web techniques must be adapted to the complex environment. In order to get a better network structure supporting mobile computing, based on the context aware consciousness theory, combined with the VC programming software, we design the algorithm of mobile computing network node, obtain the spatial statistical node model of mobile network, and use GPRS/3G base station to establish mobile network model based on the core of multimedia services. In order to verify the effectiveness and reliability of mobile computing algorithm, we calculate the network performance using VC programming software, obtain the network data transmission and delay results, and use mobile algorithm to develop multimedia licensing scheme. It provides a new algorithm for researching on mobile computing.
