In this paper, a hybrid fuzzy DEMATEL-TOPSIS model for multi criteria decision making is presented. The criteria weights are determined based on separate cause-effect assessment of a group of professionals using a modified fuzzy DEMATEL approach. The resulting criteria weights are applied to the decision analysis where an improved fuzzy TOPSIS model is presented to aid in the decision making process...
In this paper, an optimization approach to flow control in data networks is proposed. The model objective is to maximize the aggregate utilities of the data sources over soft bounds and delay constraints. The network links and data sources are considered as processors of a distributed computation system with a global objective function. The presented model works with different shapes of utility curves...

In this paper, we present a model for wireless losses in packet transmission data networks. The model provides information about the wireless channel status that can be used in congestion control schemes. A Finite State Markov Channel (FSMC) approach is implemented to model the wireless slow fading for different modulation schemes. The arrival process statistics of the packet traces determine the...
