The quality features of wireless communications have led to tremendous growth in the demand for wireless networks and has led to development of novel technologies that raise the need for broadband wireless communications. Optical wireless systems offer high transmission rates that can accommodate these broadband needs. However, optical wireless links can be prone to atmospheric changes that can result in performance degradation. Therefore, optical wireless networks should have flexible links and must be adaptive. In this paper, we focus on the adaptability of optical wireless networks and propose new heuristics for the optimization of communication delay in a flexible link regime for networks with bounded and unbounded degree transceivers. Extensive simulations are conducted to evaluate the performance of the proposed heuristics to validate the improvement in network functionality as compared to the inadaptable environment. Simulation results show that networks adopting proposed heuristics achieve a 50% reduction in average packet delay as compared to inadaptable networks.","PeriodicalId":360193,"journal":{"name":"J.

However, Jung et al.’s authentication protocol cannot provide unlinkage and mutual authentication during the communications between the vehicles and the road-side infrastructure units. In this paper, we propose an improved privacy-preserving mutual authentication protocol for vehicle ad hoc networks by using secure identity-based group blind signature, the private encryption system and the public encryption system. The proposed privacy-preserving mutual authentication protocol for vehicle ad-hoc networks satisfies mutual authentication, anonymity and unlinkability under Random Oracle Model and the Decisional Bilinear Diffie–Hellman (DBDH) assumption. In addition, the trusted center can trace malicious on-board units or road-Side infrastructure units in our protocol.","PeriodicalId":360193,"journal":{"name":"J. Convergence Inf.

However, present wall pressure computation methods are mostly based on small diameter silos. There is little system research on large diameter silos. To solve this problem, systematical research by three-dimensional finite element method on large diameter silos was carried out in this paper. Static wall pressure and wall pressure at the end of filling were analyzed. And the influence of mechanical parameters of bulk materials to wall pressure was studied. Two lamination ways to simulate filling process was studied. The result shows that scale of silo take important effect to wall pressure. Wall pressures at the end of filling of large diameter silos are much larger than static wall pressures near silos bottom. Wall pressure of filling should be considered in design of large diameter silos. Study in this paper has heavy theoretical significance and provide an important basis for the large diameter silo design.","PeriodicalId":360193,"journal":{"name":"J. Convergence Inf.

Extension rule is a method which could be used to count models. But it’s not appropriate when clause length is short or clause number is huge. After studying extension rule, we found that the satisfiability problem could be solved by hitting set algorithms. And the models could be counted with extension rule after calculating hitting sets of a clause set. Therefore, we proposed an algorithm MCBE in this paper. With Boolean algebra, MCBE could easily calculate hitting sets of a clause set. Then, it gives the number of models with extension rule. The test results show that when clause length is short and clause number is big enough, the algorithm is more efficiency than the algorithm CDP and CER.","PeriodicalId":360193,"journal":{"name":"J.

In order to obtain accurate RBF neural networks efficiently, a hybrid learning algorithm is proposed to train the neural networks, in which centers of neural networks are optimized by genetic algorithm, and widths and centers of neural networks are calculated by linear algebra methods. The proposed algorithm is applied to the modelling of the ADCES, and the results clearly indicate that the obtained RBF neural network can emulate the complex dynamic characteristics of the ADCES satisfactorily. The comparison results also show that the proposed algorithm performs better than the traditional clustering-based method.","PeriodicalId":360193,"journal":{"name":"J. Convergence Inf.

But in tall building urban area or indoor, relatively weak GPS signal makes the positioning unstable and inaccurate. TDOA(Time Difference of Arrival) is one of the most widely used positioning methods in cellular mobile communication systems, but its accuracy is not high enough to meet the growing demand. In urban where there are more base stations to support big communication capacity than in rural, the mobile terminal positioning accuracy and stability is relatively better. In order to make up for these inherent deficiency of GPS or TDOA separate positioning, this paper deduces a GPS/TDOA hybrid positioning algorithm based on federated kalman filter by giving error model, state equation and measurement equation of each local kalman filters. Simulation results show that the algorithm effectively improves the data fusion reliability and positioning accuracy.","PeriodicalId":360193,"journal":{"name":"J. Convergence Inf.

A set of agents with core capabilities can be quickly assembled to help with the gathering of relevant information and knowledge, to cooperate with each other and with other legacy systems and human managers and analysts to arrive at timely decisions in dealing with various logistics scenarios. The proposed multi-agent system (MAS), including its theoretical foundation, architecture, and implementation are presented.
