Performance Analysis and Evaluation of an Ontology-Based Heterogeneous Multi-tier Network Management System
Many of todays networks are Heterogeneous Multi-tier Networks, consisting of wired, Ad-hoc, and wireless sensor nodes. Each node type requires a management system and method to retrieve management data from the nodes. Management of the Heterogeneous Multi-tier Network can be daunting, requiring multiple management systems and manual data aggregation and analysis. A network management system to properly manage such a network was developed to automate some of the data aggregation and analysis. Ontology was utilized as the foundation of the Heterogeneous Multi-tier Network Management System to provide automation of management tasks. Analysis of the developed management system is presented to evaluate its response time and scalability. The analytical model was also utilized to perform bottleneck analysis. Results from the Network Management System deployed in a test environment supported the theoretical results.
