Comparative study on Fault tolerant routing Protocols in Mobile Ad hoc Networks

Abstract Designing of a stabilized routing protocol in MANET is challenging because of the open medium and frequent restructuring of paths. The faults in the transmission failures create malfunctioning nodes in the network. These faults can diminish the performance of the routing protocols. Identification and elimination of faulty nodes during data transmission is very crucial because of unavailability of path information. One of the research challenges for MANET is the design of efficient fault tolerant routing protocol to achieve highest packet delivery ratio. In this article the recent implementations on fault tolerant routing protocols is presented. The fault tolerant routing protocols based on numerical estimation is discussed.
