This paper presents a number of performance assessment studies of the capacity planning operations on existing networks using OPNET Modeler. We have combined a novel custom-made planning tool and OPNET Modeler to redesign and evaluate an existing network through various redesign techniques, which involve relocating the existing nodes and consolidating clusters (sub-networks). The proposed tool is...
In the past decade, many enterprise information systems (EIS) have been developed with enormous resources, such as a dedicated server per application (http, email, DNS, File, SMS, backup, etc). Thus, the overall utilization of EIS is low in compared with its resources, especially the servers. In this paper, we present a practical way to increase the utilization of EIS by consolidating many of the...
This paper presents a simple but an effective approach to restore the coverage within a wireless sensor network (WSN) when sensors fail without adding new sensors. We have considered a sensor node failure due to electrical faults or malfunctions during the initial deployment. Each sensor has a limited energy supply, and the failure of a sensor results in extra overhead during restoration of the uncovered...
Although distributed computing over a network of computers has become a reality; its success mainly depends on the performance of the underlying topology. The number of users may grow way beyond the number for which the physical topology was originally designed for, resulting in performance degradation. In such situation, the redesign of network topology is an essential scheme to improve the performance...
Many researchers view the value of the enterprise network through its utilization. If the network utilization is low, then its economical value and benefit are diminished. Also, the rapidly changes in network technologies, customers' demands and economical factors increase the opportunity for viewing the network as a dynamic infrastructure, so that its values can be adapted accordingly. Based on these...
