ABSTRACT:
Design of reliable wireless sensor network (WSN) needs to address the
failure of single or multiple network components and implementation of the
techniques to tolerate the faults occurred at various levels. The issues and
requirements of reliability improvement mechanism depend on the available
resources and application for which the WSN is deployed. This paper discusses
the different modeling approaches to evaluate the reliability and
classification of the approaches to improve it. Also the paper analyzes reliability enhancement by existing fault tolerant methods in WSN and compares the
performance of these techniques with the technique we developed. From the results
of the analysis we highlight the challenges and the characteristics of the
sensor network affects the reliability and give some scope of future research
directions in order to enhance reliability.
