In order to reduce business latency and packet loss rate, to improve the throughput of integration of heterogeneous wireless network, to achieve load diversification and to improve end quality of service, while there are many problems on the dropout rate of the traditional load balancing algorithm in processing throughput, delay and business, therefore, gateway load balancing algorithm is proposed in this paper. All terminals in the access network can reflect the effectiveness of the average network load level of the network, this algorithm will gain weight of the load in the network of small business terminal to switch to the network load which is light. First, it defines the heterogeneous networks and network terminal payoff function utility function, which are used to characterize the experience and network QOS terminal load situation, and then presents the specific processes of the gateway load balancing algorithm. Finally, switching decisional load balancing algorithm, proposed by Yan X, etc. is compared with simulation experiments and it shows that: the proposed gateway load balancing algorithm has strong robustness to achieve network load balancing and to achieve a balanced use of network resource. © 2015 SERSC.

Intelligent generating test paper can be thought of as a typical fuzzy mathematical logic problem. First, the paper analyzes the quantitative evaluation criteria of the traditional test paper generation questions and shows the existing problems in practical application of it. Then the paper introduces two different fuzzy constraints principal disjunctive normal form concept and proposes an evaluation system combining quantitative with qualitative. Viewing at the particularity of constraint satisfaction problems of intelligent generating test paper, the paper uses heuristic knowledge and applies constraint satisfaction method combining generation test with membership correction constraint satisfaction methods to realize intelligent generating test paper. The experiment shows that this method obtains good results.

The current encryption algorithm has some problems that key length is long, which is difficult to be memorized and kept so that a potential threat is caused to information security. The encryption key extracted from the biological feature is used for the encryption method, which has become a hotspot of the research. The Haar wavelet decomposition is carried out to the iris image, to extract the third-layer high frequency coefficient as the iris feature code. The random mapping function is used to generate a 128 - bit key. chi-square (χ2) test is used to analyze the key safety extracted. The results show that the key extracted from iris feature can meet requirements of the randomness and security of the encryption algorithm. © 2015 SERSC.

Aiming to overcome the shortcomings of Grid resource discovery, this paper presents a Grid resource discovery model with different layers, which adopts P2P (Peer-to-Peer) technology in Grid resource discovery mechanism. The model includes three layers based on three different peers: the Super peer-Agent, Super Peer and Ordinary peer. According to the model, this paper produces a novel Grid resource discovery algorithm, which adopts Keywords Mach algorithm based on Hash Table, employees TF-IDF to product resource keywords, locates and search s resource based on Consistent Hashing Chord, access lower latency and higher credibility peer by ant colony algorithm based on adaptively adjusting pheromone. It is testified by simulation implement that the algorithm can find the most suitable resources and improve resource discovery efficiency. © 2010 IEEE.
