Network utility maximization is a well-accepted theoretical framework that describes how congestion controls cooperate to achieve an ideal sending rate allocation, for given functions of senders and constraints the network. These network are expressed as “cost” in framework. In practice, most control mechanisms obtain feedback different from framework's “cost.” This article focuses on explicit ...

A shortest path problem is a practical issue in networks for real-world situations. This paper addresses the fuzzy shortest path (FSP) problem to obtain the best fuzzy path among fuzzy paths sets. For this purpose, a new efficient algorithm is introduced based on a new definition of ideal fuzzy sets (IFSs) in order to determine the fuzzy shortest path. Moreover, this algorithm is developed for ...
