Wireless ad hoc network management - Essay Example Until the completion of implementation, the ICT director informed me that the questions I was posing were irrelevant. They were irrelevant because they were related to operational automatic network management systems, currently not in place in our organization.Accordingly, the information collected from the ICT director, and which determined the direction of this report, centered around the management of wireless ad hoc networks and policy-based management frameworks.In designing and deciding upon a wireless ad hoc network management system, it is important to keep an eye on the desirable operational features sought in a management system for deployment in a wireless ad hoc network environment. These features, as elucidated by the ICT director and supported in the literature on the topic, are discussed below.According to Tian and Cox (2004), any network management system involves a certain amount of additional control traffic to regulate the various operational characteristics of the network. In bandwidth-constrained wireless networks, it is extremely important to minimize this signaling overhead, ensuring that the links are not congested with management traffic. Thus, as Cardei, Cardei and Du (2005) emphasize, the constrained bandwidth in wireless ad hoc networks greatly influences the choice of the mechanisms or protocols used for the various managerial tasks.Ad hoc networks generally have nodes with limited battery life, and may have limited storage and/or processing capabilities (Zhang, Hu and Fujisu, 2006). Hence, as emphasized by the ICT director, the organization needs a management system that does not burden the resource-limited network nodes with undue storage and processing requirements. Efficient signaling and minimal computation requirements will substantially alleviate the demand on the limited battery power. 2.3 Automated, Intelligent and Self-Organizing The ability for self-organization is one of the key aspects in the successful deployment of any application in an ad hoc network environment. Indeed, as our ICT Director stressed, given the dynamic nature of most ad hoc networks, an adaptive management framework that automatically reacts to changes in network conditions is required. In order to accomplish this, the management system should be able to automatically learn about the diverse capabilities of the nodes involved, and use this information as one of the criteria to assign appropriate roles to the different types of nodes. The implication here is that, as Zhang, Hu, and Fujisu (2006) stress, dynamic policies need to be supported for automated network control based on dynamic re-evaluation of communication capabilities and assets of an ad hoc network. 2.4 Secure and Robust Finally, an ad hoc network management system should be secure and robust. It should allow secure exchange of management data among authorized users, and enhance the overall survivability of the network (ICT Director). This may require the means to authenticate and authorize users, and support encryption capabilities. In addition, the system should allow reliable transmission of management data with means to detect failure and provide fault-tolerance (ICT Director). 3.0 Policy-Based Network Management In designing and deciding upon our network management architecture, our ICT Department was guided by the concerns outlined in the preceding section. Using these concerns as a roadmap for the determination of the format of our organization's ideal network management system, the ICT department identified policy-based network systems as the optimal option. The reason lies in that

History of Design - Essay Example Countries like Russia, USA and France, attended the exhibit. The palace was regarded as the first theme park offering education and entertainment. Ruskin questioned the paying of an artist on the basis of hours worked. Artistic work takes basis on very many perspectives. He stated that an artist should be paid in relation to their economically immeasurable quality of work. Artists have no power to determine their financial value but rather this depends primarily on the buyer. He postulated close monitoring of the worker through close supervision for better results. Charlie was born in Glasgow Scotland in the year 1868. He later joined Glasgow school of art in the year 1884. Having completed his studies in the year 1889, he became an architectural assistant. In the year 1890, Charlie won a scholarship in Italy which acted as a gateway to his success in the field of art. Charlie is highly regarded as a leading factor for the development of various designs. An excellent example is the textile designs and interior designs. He also brought the idea of modernism. Charlie was greatly influenced by the Japanese style due to its simplicity, style and use of natural materials. Some of these designs are’ Argyle Chair, High black chair, Hill House chair and Ingram chair. In conclusion, Charlie undertook great projects in Europe like; Hill house, Windy Hill, Former Daily Record Offices Glasgow, and Lighthouse Glasgow. Queens Cross church project was rated as one his
