The latest technology MANETs is being studied widely and attracting a large variety of applications. Due to varying network topology, The most common challenging factor in MANET is routing [1][2]. Future applications of MANETs are expected to be based on all-IP architecture and be capable of carrying multitude real-time multimedia applications such as voice and video as well as data. It is very necessary for MANETs to have an efficient routing and quality of service (QoS) mechanism to support diverse applications. In this research paper, we study the various unipath routing protocols such as DSDV, WRP,GSR,FSR,AODV,DSR,CBRP and various Multipath routing protocols such as AOMDV,SMR,AODVM,MSR.
