Congestion detection and avoidance using fuzzy systems
(2012) Mustafa, Mohammed N.
In this thesis, A congestion problem is studied, The study is talking about how to detect the congestion and how to avoid it. Service providers are interested in optimizing their networks performance because of the high cost of network assets and commercials, and competitive nature of Internet service provisioning, This leads them to reduce congestion hotspots and to improve resources utilization across the network, which, in turn, results in an increased revenue collection. One of the ways to achieve such goals is through applying the controller scheme and by early detect it, we use Fuzzy Systems to detect congestion and avoid it, Because it improve that purpose. In this Thesis an algorithms to detect and control congestion problem based on Fuzzy Systems is presented, this algorithms are called Fuzzy Logic Congestion Detection (FLGD) and Fuzzy Logic Controller (FLC). This information about these algorithms are simulated, using MATLAB Simulation program. The proposed algorithms showed good performance and good result in reduce delay and raise throughput.
