Working Paper on Scalability Comparison of AODV and DSDV Routing Protocols in MANETs
Richa Singla,  Amit Chaudhary
Ad-hoc networks form instantaneously without the need of any infrastructure or centralized controller. This type of peer-to-peer system results that each node, or user, in the network can act as a data endpoint or intermediate repeater. Thus, all users work simultaneously to improve the reliability of network communications. These networks are also popularly called as "mesh networks" because the topology of network communications resembles a mesh. The redundant and the unnecessary communication paths provided by ad hoc mesh networks significantly improve the fault tolerance for the network. Also, the ability of the data packets to "hop" from one user to other effectively extends the network coverage area and provides a solution to defeat non-line of sight (LOS) issues.As mobile networking continues to experience increasing popularity; the need to connect large numbers of wireless devices will become more prevalent. Many recent proposals for ad hoc routing have certain characteristics which may limit their scalability to large networks. Mobile Ad Hoc Networks (MANETs) is a collection of wireless mobile nodes connected by wireless links forming a temporary network without the aid of any infrastructure or any centralized administration. Nodes within each other’s radio range communicate directly via wireless links, while those that are far apart use other nodes as relays in a multi-hop routing fashion. These protocols typically suffer from a number of shortcomings, such as high routing overhead and limited scalability. The scalability of current on-demand and table driven routing protocols is evaluated through the selection of a representative from the class of protocols. The performance of the un-modified on-demand protocol and table driven routing protocol is compared with each of the scalability modifications. Based on the observations, conclusions can be drawn as to the expected scalability improvement which can be achieved by each modification. Our objective is to thoroughly capture and analyze the impact of scalability on MANET performance using reactive (AODV) routing protocol and proactive (DSDV) by varying number of source nodes in the MANET. For this, there is a plan to use Performance Metrics i.e. Throughput, Packet delivery Ratio and end to end delay to analyze the impact of scalability on Reactive and Proactive Routing Protocol category in MANET.
