An efficient and reliable network alignment serves to find the mapping with maximum similarity between different networks, which is a way to improve our understanding of biology system and biological process. To build such network alignment is a foremost challenging task in computational biology because it involves the bipartite graph matching problem, which is an NP-hard problem. In this work, we...
In this paper, two methods were considered to estimate the distance, which aims to study the influence of external environmental factors on localization accuracy. The first method is log-normal shadowing model (LNSM), which estimates the distance through the received signal strength indicator (RSSI). The second method is improved algorithm based on RBF neural network (RBFNN). Two different experimental...
Aiming at the problem of reliability redundancy design algorithm, this paper presents an adaptive particle swarm optimization algorithm with foraging behavior. In this method, the bacterial foraging process is introduced into the adaptive particle swarm optimization algorithm, which can give the function of particle movement and turning, improve the ability of local search and avoid premature behavior...
Cryptographic Hash function is perhaps the most versatile cryptographic algorithm, it is widely used in a variety of security applications and network protocols. It has been widely used mainly in the digital signature, authentication and other fields. MD5 algorithm is one of the Hash function algorithm. MD5 algorithm is a typical representative of the MD structure and is a typical representative of...
In this paper, the feasibility of using probabilistic causal-effect model is studied and we apply it in particle swarm optimization algorithm (PSO) to classify the faults of mine hoist. In order to enhance the PSO performance, we propose the probability function to nonlinearly map the data into a feature space in probabilistic causal-effect model, and with it, fault diagnosis is simplified into optimization...
Cognitive radio technology is proposed to solve the problem of the scarce radio spectrum resources. In view of the spectrum allocation in cognitive radio technology, this paper first analyses the three allocation rules based on graph coloring theory which include the sum reward rules, the max-min reward rules and the proportional-fair reward rules. The simulations of the three algorithms adopt the...
