| Summary: | Mobile Ad-hoc NETwork is a collection of two or more mobile nodes
that has no infrastructure support, and every mobile node can work as a router. In
MANET mobile nodes can move arbitrarily, consequently the system topology changes
in random manner. Practically, in order to allow mobile nodes to communicate with
each other, a routing protocol is desired to discover routes between nodes, and
determines how information is transmitted from a source node to a destination node.
Basically, MANET routing protocols are classified into two categories: On-demand and
Table-driven. On-demand protocols are utilized whenever a communication is needed.
The most widely researched on-demand MANET protocols: DSR (Dynamic Source
Routing protocol) and AODV (Ad hoc On-demand Distance Vector protocol).
Objective: The main aim of this paper is to simulation based analysis of DSR and
AODV protocols on the basis of different performance metrics which are packet
delivery fraction (PDF), routing overheads (RO), and end-to-end delay. The simulation
is performed through the simulation tool Global Mobile Simulator due to its open
source simplicity and free availability. Results: in considered mobility scenarios,
AODV gives better PDF than DSR, while DSR gives better RO and End-to-End delay
in most mobility scenarios. Conclusion: In this article, an effort has been made to
concentrate on the comparative study of well known on-demand protocols (AODV and
DSR). Consequently, a single MANET routing protocol cannot accomplish best in all
circumstances. Therefore, the preference of MANET routing protocol should be done
carefully according to the conditions of the definite application. |
