Research on Implementation and Comparison of Routing Protocols in MANET using NS2

A Mobile Ad hoc Network (MANET) is a type of temporary computer-to-computer connection. In Ad hoc mode, you can set up a wireless connection directly to another computer without having to connect a wireless access point or router. Ad hoc networks are useful when you need to share files or other data directly with another computer but don't have access to a wireless network. Mobile Ad-hoc wireless networks holds the promise of the future, with the capability establish networks at anytime, anywhere. The Efficient routing protocols can provide significant benefits to Mobile Ad hoc Networks, in terms of both performance and reliability. Many routing protocols for such networks have been proposed so far. Among the most popular ones are Ad hoc On-demand Distance Vector (AODV), Dynamic Source Routing Protocol (DSR) and Destination-Sequenced Distance-Vector Routing protocol (DSDV). This paper presents a research on implementation and comparison of wireless routing protocols AODV, DSR and DSDV based on metrics such as throughput, packet delivery ratio and average end-to-end delay by using the NS-2 simulator.
