MANET is a self organized and self configurable network without existing infrastructure. Due to limited resources in MANETs, to design an efficient and reliable routing strategy is still a challenge. A number of protocols have been proposed for efficient routing in MANET. It is quite difficult to determine which protocol is suitable for different network conditions. In this paper concentrate wide range of existing routing protocols and provide comparison between them. Here also discuss Opportunistic data forwarding. One of the reasons why opportunistic data forwarding has not been widely utilized in mobile ad hoc networks (MANETs) is the lack of an efficient, light-weight proactive routing scheme with strong source routing capability. A new routing protocol named PSR for ODF in mobile ad-hoc networks.
