AB  - The wireless communication is creating revolution in the present day life. A WSN is a system of
wirelessly communicating nodes where each node is equipped with multiple components. Wireless sensor
networks plays a major role in providing support for observing, processing and making decisions depending
on the observations. WSN is a self-organized network that consists of large number of low cost and low
powered sensor devices called sensor nodes. These networks are most widely used in industries, military,
surveillance, environmental monitoring, etc. WSNs are prone to be affected by different failures such as power
depletion, environmental impact, interference, communication link failure, dislocation of sensor node and
collision. If those faults are not handled properly they will not meet their desired goals. So, a sensor network
should be fault resistant. Fault tolerance is the property that enables asystem to continue operating properly
in the event of failure of some of its components. Fault-tolerance mechanisms such as fault-detection
and fault-recovery are needed to protect these networks from various faults. In this study, a butterfly network
based WSN is presented that enhance the reliability and fault tolerance capability of the WSN.
