A SURVEY ON VARIOUS FAULT TOLERANCE DEPLOYMENT MECHANISMS IN WIRELESS SENSOR NETWORKS

Wireless Sensor Networks (WSN) is different from other wireless networks due to power consumption, size, cost and their trade offs. One of the major issues in design and performance of WSNs is fault tolerance deployment of sensor nodes and base stations in WSN to achieve increase network lifetime, energy consumption, data reliability, accuracy and reduce failure of components. Deployment strategy poses different research challenges. This paper presents an analysis of fault tolerance deployment mechanisms in WSN to identify the strengths and weaknesses of each one of these mechanisms. This paper presents the scope of research directions in order to help researchers who are working in this field.
