摘要:

In the environment of heterogeneous wireless networks, it is vital to select a currently optimal network for applications and subscribers. The use of multiple attribute decision making (MADM) for heterogeneous network selection can provide subscribers with satisfactory service quality. Converting heterogeneous network selection into a MADM problem, the authors present an improved algorithm for MADM based on group decision theory. The algorithm combines weight vectors of multiple attribute decision making to obtain a combinational weight vector. Then the results’ compatibility will be assessed. If they do not meet the requirements of compatibility, the judgment matrix will be modified until a comprehensive vector that satisfies compatibility requirements is produced. The vector is combined with simple weighting method (SAW) for network selection. Simulation shows that the algorithm can provide users with satisfactory quality of service (QoS).

Abstract:

In the environment of heterogeneous wireless networks, it is vital to select a currently optimal network for every subscriber for each application. The use of multiple attribute decision making (MADM) for heterogeneous network selection can provide subscribers with satisfactory service quality. Consequently, converting heterogeneous network selection into a multiple attribute decision making (MADM) problem, we present an improved multiple attribute decision making (MADM) algorithm based on group decision theory in this paper. At first, the algorithm combines weight vectors of multiple attribute decision making to obtain a combinational weight vector. Then the results' compatibility will be assessed. If they do not meet the requirements of compatibility, the judgment matrix will be modified until a comprehensive vector that satisfies compatibility requirements is produced. Then the vector will be combined with SAW method for network selection. The simulation results show that the algorithm can provide users with satisfactory quality of service (QoS).
