Abstract
Wireless mobile ad-hoc networks are characterized as networks without any physical connections. Multipath routing is a new extension to many traditional routing protocols in MANETs. Using multipath routing in MANETs can save energy, reduce frequent routing update, enhance data transmission rates, and increase wireless network bandwidth. There are numerous Multi-paths on-demand routing algorithms exist to discover several paths instead of one, once the routing is performed. In this paper a new Robust Fault Tolerant AOMDV (RFTA) algorithm is proposed to improve the fault tolerance and efficient routing in mobile adhoc network (MANET). The algorithm is compared with various multi path routing protocols like SMR, SMS and MDSR. The efficiency of the protocol has been evaluated on different scenarios using performance metrics such as packet delivery ratio and end-to-end delay.KeywordsAODMVend-to-end delayfault tolerancepacket delivery ratioSMRSMS
