Performance Analysis of Non-Realistic Routing Protocol using Random Waypoint Model in MANET

Abstract

A mobile ad hoc network (MANET) is a collection
of wireless nodes connected via wireless networks and has no set
structure. MANETs feature a self-organized routing topology in
which mobile nodes are free to move, making it difficult and
crucial to construct a stable and reliable network. Thus, failure of
the route is also regarded as a prime factor affecting the
efficiency of any MANET routing protocol. The breaking of the
connection between two routes or more nodes will cause the
failure of the route specifically in the non-realistic routing
protocol. In a network of mobile nodes, the link break is mainly
based on the mobility of individual nodes. Therefore, the
objective of this research is to investigate the performance of
proactive DSDV and reactive AODV routing protocol using the
Random Waypoint(RWP) mobility model in MANET. NS-2
network simulator is used to simulate the MANET environment
and BonnMotion is to create a movement of mobile nodes that
integrate with the routing protocol. The network performance
metrics used are throughput, packet delivery ratio, and average
end-to-end delay. In addition, three simulation scenarios have
been conducted to compare AODV and DSDV routing protocols
with varying numbers of nodes, a comparison of AODV and
DSDV routing protocols with varying pause time, and a
comparison of AODV and DSDV routing protocols with varying
mobility speed. The result from the three scenarios analysed and
concluded that the RWP mobility model with AODV gives a
better performance of throughput with 869.69 kbps and Packet
Delivery Ratio (PDR) with 83.00% meanwhile, RWP with DSDV
is better for the average end-to-end delay(EED) with 212.970 bps.
