Mobile Ad-hoc Network (MANET) Routing Protocol Comparison between Temporary Ordered Routing Algorithm (TORA) and Dynamic Source Routing (DSR) – A Review

The apparition of mobile ad-hoc networking is to support robust and efficient operation in mobile wireless networks by incorporating routing functionality into mobile nodes. Such networks are envisioned to have dynamic, sometimes rapidly-changing, multihop topologies which most of the time are composed of relatively bandwidth-constrained wireless links. The mobile nodes are put together to form an ad-hoc network without the use of any centralised structure. It functions like a router in order to maintain connectivity in the network since there is no centralized infrastructure to establish communication. Meanwhile, collections of these mobile nodes are frequently broken due to lack of maintained infrastructure. Hence, the need for Routing Protocols that works at a low data rate and can dynamically adapt to the changing topologies. This paper presents a review of performance comparison between Temporary Ordered Routing Algorithm (TORA) and Dynamic Source Routing (DSR) protocols to suggest a promising protocol that will overcome the limitations associated with MANETs. NS2 network simulator is used in the experiment over a LAN.
