Multi-Controller Placement Towards SDN Based on Louvain Heuristic Algorithm

Robust PID controller tuning based on the heuristic Kalman algorithm

This paper presents a simple but effective tuning strategy for robust PID controllers satisfying multiple H∞ performance criteria. Finding such a controller is known to be computationally intractable via the conventional techniques. This is mainly due to the non-convexity of the resulting control problem which is of the fixed order/structure type. To solve this kind of control problem easily an...

Loose Management for Multi-controller in SDN

Tools for a Multi-Controller SDN Architecture

Software Define Network (SDN) is a recent paradigm based on the separation between the data plane and the control plane, allowing to handle the traffic network by means of software. The SDN ecosystem is fragmented due to the multitude of different controller platforms. This creates a danger of a controller lock-in for SDN application developers and for SDN network operator. In order to tackle t...

A Hybrid Meta-Heuristic Algorithm based on Imperialist Competition Algorithm

The human has always been to find the best in all things. This Perfectionism has led to the creation of optimization methods. The goal of optimization is to determine the variables and find the best acceptable answer Due to the limitations of the problem, So that the objective function is minimum or maximum. One of the ways inaccurate optimization is meta-heuristics so that Inspired by nature, ...

New clustering proposals for Twitter based on the Louvain algorithm

Document clustering is a problem that has been successfully solved in contexts where the size of the documents is big. When the size of the documents has a limit of 140 characters as in Twitter, then this problem becomes more challenging. In this work we will address this problem, which is one component of a larger task of reputation monitoring of an entity using real time data from Twitter. We...
