A group of fixed or mobile communication devices that does not have a stable infrastructure to communicate with each other is known as mobile ad-hoc network. In MANET there is very important role of nodes. All nodes can communicate with each other by directly or indirectly method. Routing is a most important part in MANET. There are three types of protocols the authors use for routing i.e. Proactive, reactive and hybrid. In this paper, they study the AODV (Ad-hoc On-demand Distance Vector), DSR (Dynamic Source Routing), OLSR (Optimized Link State Routing protocol) routing protocols for DB (DataBase) and HTTP (Hyper Text Transfer Protocol) traffic types.
