A Survey on Communication Link Fault Tolerance For Wireless Sensor Networks

John Divakaran

This paper describes how the path fragments are rectifying during the transmission time and how the energy are handled in wireless sensor networks are explored. Wireless sensor networks are used to monitoring the application like chemical sensing, fire detection, weather condition. In this homogenous application some problems may occur during the data transmission time. There are various techniques that are available to rectifying path fragments problem and reduce the energy consumption during data transmission as well as continuous monitoring. The various algorithms mainly focused to solve the path fragments with lowest possible energy and end to end transmitting delay. The fault tolerances are classified based on the different kinds of fault which occur in WSN that are discussed in detail. In this paper present a survey on fault during the data transmitting time and how that are detect and recovery from that fault in WSNs in theoretical point of view research.
