| Abstract | The recent improvement of wireless communication networks has made possible the use of such networks at the lowest levels of factory automation systems, which typically imposes severe requirements in terms of both real-time performance and dependability. However, Industrial plants represent a hostile environment, for communication systems, due to the presence of different kind of noises. The presence of these noises can easily inflict damages on the wireless information signals and creates erroneous interruptions on the data transmitted. In most wireless industrial systems, such errors and interferences are modelled by AWGN and Gilbert-Elliot models. In this paper, we have attempted to assess the performance of the wireless fieldbus network on the aforementioned channels in order to evaluate the potential performance of AWGN and its comparison with the Gilbert-Elliot channel. Furthermore, the handling of asynchronous alarm packets is done by considering two methods of Late and Immediate technique. The NS2 simulation results have proved the superior performance of AWGN model in comparison with Gilbert — Elliot model. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
