| Abstract | In this research paper we undertook the problem of Location Determination of Mobile nodes in a Wireless Local area network, as finding out the location in a wireless environment is to-date not very easy, cheap and accurate using 802.11b technology. We used the classical method of Triangulation with a little alteration which is later on described in the paper. Another method we used is the methods of calibration by research to produce more accurate results and also to cross verify the results of the method of Triangulation. The work in this paper attempts to illustrate the different aspects of the problem of location determination in WiFi networks. We started with an investigation of the influence that network characteristics have on the ability of middleware location determination protocols to accurately estimate position of mobile nodes. We presented an implementation based study that demonstrated the strong relationship between the two of the location determination methods and their performance. The main objective of this paper is to provide method in which no dedication hardware is required. Only Wireless Lan card is required and can be placed in any suitable location. The significance of this result lies in allowing a network designer to make a suitable tradeoff between QoS of location determination and other application protocols while choosing a network topology. The combination of two methods reduced the error rate of locating a mobile node to a great extent. The results were being plotted on a given map using both the algorithms. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
