In order to get the weight vector of the attribute, we establish an optimization model based on the basic ideal of traditional grey relational analysis (GRA) method, by which the attribute weights can be determined. Then, based on the traditional GRA method, calculation steps for solving intuitionistic fuzzy multiple attribute decision-making problems with completely known weight information are given. The degree of grey relation between every alternative and positive ideal solution is calculated. Then, a relative relational degree is defined to determine the ranking order of all alternatives by calculating the degree of grey relation to both the positive-ideal solution (PIS). Finally, an illustrative example is given to verify the developed approach and to demonstrate its practicality and effectiveness.","PeriodicalId":360193,"journal":{"name":"J. Convergence Inf.

Since there is no central node in the network, it is necessary to use a decentralized algorithm for synchronizing the local time slot reference. In this paper, the convergence performance of the decentralized slot synchronization algorithm for wireless Ad Hoc networks is analyzed for the first time. By introducing a virtual benchmark, we proved that the algorithm is equivalent to a distributed average problem. A mathematic model of the decentralized slot synchronization algorithm is then established for multi-hop network. Moreover, the convergence of the algorithm is proved in mathematic method and studied via simulation experiment.","PeriodicalId":360193,"journal":{"name":"J. Convergence Inf.

In this paper, Cayley graph model is suggested for wireless Mesh Networks (WMN) with MIMO channels for efficient routing and fair scheduling. The model is based on the multiple interfaces, directional antennas, single channel mesh model. And the link edges or active edges can be viewed as connections between node pairs. A node can have as many links as its interface permits, but links are limited not conflicting with the interference model in wireless network. By placing edges into different channel plane virtually, the Cayley graph model allows a node to use maximum active edges under orthogonal channels. The model is helpful for WMN routing and scheduling schemes with the symmetry coding character in WMN. Consequently, layered active edge group scheduling algorithm and destination oriented routing schemes are proposed for maximum capacity and throughput. Furthermore, efficient transformations are used to take advantage of previous maximum active edge group scheduling for fairness.","PeriodicalId":360193,"journal":{"name":"J. Convergence Inf.
