A survey on on-demand multipath routing protocol in MANETs

A mobile ad hoc networks (MANETs) consist of a collection of wireless mobile nodes which dynamically exchange data among themselves without a reliance on a fixed base station or a wired backbone network. Because of these characteristics, path connecting source nodes with destination may be very unstable and go down at any time, making communication over ad hoc networks difficult. In most cases, the ability of creating multiple routes from source to destination is used to provide a backup route. When a primary route fails to deliver the packets in some wa, the backup is used. This provides a better fault tolerance in the sense of faster and efficient recovery from route failures. This paper will address the previous study on multipath routing protocols in MANETs, benefits and applications.
