Performance metrics and comparative analysis of AODV and DSDV routing protocols for varying sources in Mobile Ad hoc Networks

Mobile Ad hoc networks are a system of communicating nodes that do not have any specific infrastructure. Absence of central administration, unlike traditional networks, makes them an easy to implement access system.? It provides for handy creation in emergency situations. Nodes are able to communicate with a hotspot (data service source) either directly or through indirect relaying system. A node can act as client or a relaying node. Also, a node has to make hops in order to reach the source node. These hops are predefined rather random and at the same time they are subject to variation due to mobility and quality of service. This means that hops are not aimless or random, rather they are authenticated and maintained within a node for routing. Routing becomes more complex when mobility is the chief characteristic of an Ad hoc system. Nodes appear and disappear and their information is updated by other nodes from time to time. Updation of routing information is also a complex phenomenon. It requires a number of important resource to maintain reliable and resilient routing procedure and process. To this effect, different routing protocols have been deviced to address the above stated problems. Security, authenticity, reliability and seemless communication are the bedrock of such design. This paper discussed ?two of the most important distance vector (DV) routing protocols namely (Destination Sequenced) DSDV and (Ad hoc On Demand) AODV. Rationale for the choice of these protocols is that their core concept segregates them into table driven/ proactive (DSDV) and On Demand/ Reactive (AODV) types of MANET Routing Protocols. In introduction their modus operandi shall be discusses. In next section their design and issues related to them will be discussed. Further there is a section that discusses their chief characteristics and performance metrics in order to comprehend their usability is a given setting. Finally in the last two sections a comparative analysis based on simulation results is conducted and concluded.
